Agronomic Characteristics Of Novi Sad Winter Vetch Cultivars, V. Mihailović, A. Mikić, B. Ćupina, S. Vasiljević, D. Milić

IGC Proceedings (1977-2023)

Genus Vicia. contains important annual food and forage species such as field bean, V. faba., narbon vetch, V. narbonensis, and common vetch, V. sativa (Maxted, 1995), while Hungarian V. pannonica Crantz and hairy vetch V. villosa also play an important role in the Balkans. Winter vetches are excellent forage catch crops useful for sustainable agriculture and organic farming (Ċupina et al., 2004). Our study was aimed at determining the agronomic characteristics of the winter vetch cultivars developed in Novi Sad, assessing thus their ability for successful growing in the prevailing conditions of Serbia and Montenegro.

New Pigeon Pea (Cajanus Cajan) Hybrids With Desirable Forage Traits, P. B. Alcantara, J. A. Usberti Jr., C. A. Colombo, V. B. G. Alcantara, R. Usberti, M. A. C. Lucena, M. Harris

IGC Proceedings (1977-2023)

Pigeon pea is a tropical forage legume usually sown in mixed pastures with tropical forage grasses. Most of the available cultivars shows erect and tall plants with poor tillering potential, breakable thick stems, low leaf/stem ratios (fresh/dry matter) and low persistence under animal grazing. It shows a high dry matter production, due to low leaf/stem ratios (Barnes & Addo, 1997). Pigeon pea shows good crude protein levels/dry matter (ranging from 14-23%) and regular in vitro digestibility indexes (52-58%) (Karachi & Matata, 1996); animal consumption is affected by high tannin levels of young leaves. Being a self-pollinated species, the variability for …

Development Of High-Yielding And Early-Maturing Korean Hairy Vetch, C. N. Shin, K. H. Ko

IGC Proceedings (1977-2023)

There are a number of forage cultivars recommended by the government, but only a few winter-spring legumes are available for the farmers in Korea. Hairy vetch has superior winter hardiness and produces high dry matter (DM) yield compared with crimson clover, Persian clover, rose clover, common vetch and Chinese milk vetch in Korea. However, under a double cropping forage production system an early maturing vetch cultivar was more productive than a late maturing one (Shin et al., 2000). The objective of this research was to develop a high yielding and early flowering new hairy vetch cultivar derived from an …

Seasonal Variation Of Tannin Content On Pigeon Pea (Cajanus Cajan (L.) Millsp) Plants, Rodolfo Godoy, P. M. Santos, L. A. R. Batista

IGC Proceedings (1977-2023)

Tannins reduce forage digestibility and palatability by reacting with proteins (Makkar, 1989) and due to that, tannin content is considered to be an important characteristic of leguminous crops and it has been used as a selection criterion on pigeon-pea improvement programs (Godoy et al., 1994). In Southeastern Brazil, pigeon pea is less consumed by bovines in the rainy season (October through March) than in the dry season (from April on), when flowering occurs. Alencar et al. (1991) found very little consumption by Canchim cows during the rainy season, and Lourenço et al. (1984) recommend pigeon-pea for feeding bovines in …

Travel Across The "Narrow Neck Of Land", Matthew Roper

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

In recent years a number of Book of Mormon scholars have associated the "narrow neck of land" mentioned by Mormon with the Mexican Isthmus of Tehuantepec. Mormon states that it was approximately "a day and a half's journey for a Nephite, on the line Bountiful and the land Desolation, from the east to the west sea" (Alma 22:32). This was the speed "for a Nephite," and presumably a group of people or even a non-Nephite might take longer. Moreover, since Mormon was speaking of a fortified line of defense along which communication would be desirable, the phrase "for a Nephite" …

Breeding Lotus Australis Andrews For Low Cyanide Content, D. Real, G. A. Sandral, J. Warden, L. Nutt, R. Bennett, D. Kidd

IGC Proceedings (1977-2023)

Lotus australis Andrews is a native perennial tetraploid legume (2n=4x=28) widely distributed throughout Australia (Figure 1). It is highly variable with 14 botanical varieties reported in the Australian Plant Name Index (http://www.anbg.gov.au). Despite broad adaptation within L. australis no cultivars have been developed for cultivation. One of the main barriers to cultivation is the reported cyanogenic nature of the species (Foulds, 1982), which makes it potentially toxic when plant cyanogenic glycosides are fully hydrolysed to form hydrogen cyanide (HCN). Foulds (1982) also reported that the cyanophoric trait was polymorphic at seedling and adult stages with 12% of plants acyanogenic in …

Analysis Of Genetic Diversity In White Clover (Trifolium Repens) Breeding Populations Using Agro-Morphological And Rapd Markers, T. R. Sharma, S. Singh, R. Rathour, S. K. Sharma

IGC Proceedings (1977-2023)

White clover is an important forage legume for temperate regions, but very little is known about the genetic organisation of its breeding populations. The low amount of variability in the Indian collections of white clover for genetic improvement warrants the introduction of new germplasm and collecting local ecotypes for characterisation, utilisation and conservation. Several molecular techniques have been used for germplasm characterisation, variety identification, marker development and identification, molecular diagnostics, phylogenetic studies and diversity analysis. Because of its simplicity, rapidity and reliability, the RAPD technique has been used extensively for diversity analysis. The present study aims at characterising white clover …

Concurrent Selection For Low Coumarin And Multi-Stemmed Crowns In Annual Sweetclover, Gerald R. Smith, G. W. Evers

IGC Proceedings (1977-2023)

Annual sweetclover (Melilotus alba Desr) is a reseeding, drought tolerant forage legume that is well adapted to the alkaline and neutral soils of the US Southern Great Plains. Coumarin is a phytochemical found in sweetclover that is a precursor to dicoumarol, which causes a toxic bleeding disease in cattle. The inheritance of low coumarin in sweetclover is determined by a single gene (Goplen et al., 1957), but current low coumarin cultivars are all biennial, northern types. The ability of annual sweetclover to develop a multi-stemmed crown, similar to alfalfa (Medicago sativa L.), is also under genetic control …

Improving The Utilisation Of Germplasm Of Trifolium Spumosum L. By The Development Of A Core Collection Using Ecogeographical And Molecular Techniques, K. Ghamkhar, R. Snowball, S. J. Bennett

IGC Proceedings (1977-2023)

A core collection is a sub-set encompassing more than 70% of the variability of all accessions held in a collection (Brown 1995), the development of one for Trifolium spumosum (bladder clover) could assist in future development of the cultivar within southern Australia. The aim of this work is to develop a core collection of Trifolium spumosum as a model for other pasture legume species using molecular and ecogeographical data.

Evaluation Of White Clover Breeding Lines In The Australasian Region, Mohamed Z. Z. Jahufer, D. R. Woodfield, J. L. Ford, K. H. Widdup, J. F. Ayres, L. A. Lane

IGC Proceedings (1977-2023)

The accuracy of predicting breeding line performance across target environments is a significant criterion in the development of cultivars with broad or specific adaptation. This paper characterises the type and magnitude of genotype-by-environment (GE) interactions estimated from a multi-site white clover (Trifolium repens L.) breeding line evaluation trial conducted across sites in New Zealand and Australia.

Quantitative Trait Locus Analysis Of Morphogenetic And Developmental Traits In An Ssr And Aflp-Based Genetic Map Of White Clover (Trifolium Repens L.), M. T. Abberton, N. O. I. Cogan, K. F. Smith, G. Kearney, A. H. Marshall, A. Williams, T. P. T. Michaelson-Yeates, C. Bowen, E. S. Jones, A. C. Vecchies, J. W. Forster

IGC Proceedings (1977-2023)

Molecular marker-assisted plant breeding is a key target for the temperate legume pasture crop white clover (Trifolium repens L.). The first genetic linkage map of white clover has been constructed using self-fertile mutants to derive an intercross based fourth and fifth generation inbred parental genotypes (F₂[I.4R x I.5J]). The framework map was constructed using simple sequence repeat (TRSSR) and amplified fragment length polymorphism (AFLP) markers. Eighteen linkage groups (LG) corresponding to the anticipated 16 chromosomes of white clover (2n = 4x = 32), with a total map length of 825 cM were derived from a total of …

Quantifying The Variation In Protein Content In White Clover (Trifolium Repens L.), A. H. Marshall, E. Sizer, A. Kingston-Smith, A. Williams, M. T. Abberton

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) is the main legume in temperate pastures. It has relatively low levels of water-soluble carbohydrate but produces forage of high quality with a high crude protein (CP) content and dry-matter digestibility (Beever, 1993). Some studies have suggested that the forage quality of white clover can be problematic because its high CP content may contribute to inefficient use of nitrogen in the rumen and exacerbate diffuse pollution via excreta (Waghorn & Caradus, 1994). The development of white clover germplasm with lower CP content would potentially benefit forage production and grassland management. A study was carried …

New Approaches To Clover Breeding, M. T. Abberton, T. A. Williams, T. P. T. Michaelson-Yeates, A. H. Marshall, C. Jones, E. Sizer-Coverdale, R. P. Collins

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) and red clover (T. pratense) are the major forage legumes of temperate pastures. Breeding efforts have focused on overcoming the constraints to productivity and reliability in this species and thereby optimising their contribution to mixed swards. In recent years there has been an increased emphasis on livestock production and the efficient utilisation of forage material in the rumen. In this paper we report on a shift in the aims of forage legume breeding at IGER, building on a strong agronomic platform but giving greater consideration to the environmental footprint of our varieties …

Forage Quality Of White Clover (Trifolium Repens L.) X Ball Clover (T.Nigrescens Viv.) Hybrids Over Three Harvest Years, T. P. T. Michaelson-Yeates, M. T. Abberton, A. H. Marshall, T. A. Williams, H. G. Powell, P. Olyott

IGC Proceedings (1977-2023)

Introgression of reproductive traits from the annual, profusely flowering species ball clover into white clover is one route to improve seed yields in T.repens. The interspecific cross produced F₁, backcross 1 (BC₁), backcross 2 (BC₂) and backcross 3 (BC₃) plants with white clover as recurrent parent (Marshall et al., 2002). These hybrids were found to be comparable with white clover for yield and persistency but produced 30% more flowers and their forage quality, relative to white clover was investigated.

Forage Quality Of White Clover (Trifolium Repens L.) X Caucasian Clover (T.Ambiguum Bieb.) Hybrids Over Three Harvest Years, T. P. T. Michaelson-Yeates, A. H. Marshall, M. T. Abberton, T. A. Williams, P. Olyott, H. G. Powell

IGC Proceedings (1977-2023)

Interspecific hybrids have been produced from crosses of white clover, a stoloniferous species with Caucasian clover, a rhizomatous species. Using white clover as the recurrent parent first and second generation backcross (BC₁ and BC₂) plants have been produced that have both rhizomes and stolons and are more drought tolerant than white clover (Marshall et al., 2001). Forage quality of these interspecific hybrids was investigated to determine whether introgression of the rhizomatous trait has any impact on forage quality.

Breeding White Clover With Improved Tolerance Of Nitrogen Fertiliser, T. A. Williams, M. T. Abberton, P. Olyott

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) is often considered a forage legume with a primary use in 'low input/ low output' systems. One facet of this is the perception that the persistency of this species is poor when Nitrogen (N) fertiliser is applied. However, new varieties of white clover are able to play a significant role in highly productive systems (Williams et al., 2000) and show consistent yields over ten years at a range of applied N levels (Williams et al., 2003). Germplasm improvement for nitrogen tolerance has been carried out with the aim of not only allowing white …

Evaluation Of A White Clover Variety With Increased Resistance To Stem Nematode (Ditylenchus Dipsaci) Under Sheep Grazing And Cutting, T. A. Williams, M. T. Abberton, K. A. Mizen, P. Olyott, R. Cook

IGC Proceedings (1977-2023)

Stem nematode (Ditylenchus dipsaci (Kühn) Filipjev) is a major pest of white clover (Trifolium repens L.) in UK pastures (Cook et al., 1992a) and in other parts of the world. In a previous trial, resistant and susceptible selections yielded the same in three years in the absence of the nematode but, on infested plots, the susceptible yielded the same as the resistant selection in year 1 but only 68 and 58% in years 2 and 3, as the nematode infestation increased (Cook et al., 1992b). We have now developed varieties with enhanced resistance to this pest …

Relationships Between Nitrogenase Activity, Dry Forage And Water Soluble Carbohydrates Content Of Selected Red Clover Genotypes, T. Simon, H. Jakesova

IGC Proceedings (1977-2023)

Improving N₂ fixation of perennial forage legumes through selection and breeding reduce reliance on soil N and N fertiliser, whilst enhancing residual benefits to subsequent crops and increasing legume forage dry matter (DM) yield. Simultaneously with the selection for enhanced N fixation, new legume genotypes should be evaluated on forage quality, especially nutrient concentration and dry matter digestibility.

Evaluation Of Lucerne Cultivars For Dry Matter And Seed Production In Latvia, S. Rancane, M. Sparnina

IGC Proceedings (1977-2023)

Lucerne is highly productivity and has a high quality. Nevertheless, lucerne growing in Latvia is limited, because of a large area of acid soils (pH_KCl<5.8) as well as low and unstable seed yields (Berzins, 2002). In recent years lucerne has taken a more important place in forage production in Latvia, because it is a fast growing crop and in good years gives 3-4 harvests per season. It is important to determine which cultivars of lucerne are more productive and give good seed yields every year in Latvia (Luksa, 2002).
