Drought Tolerance Of Interspecific Hybrids Between Trifolium Repens And Trifolium Ambiguum, A. H. Marshall, M. T. Abberton, T. P. T. Michaelson-Yeates, I. Rhodes, A. Williams
IGC Proceedings (1977-2023)
Hybrids between the stolonifeous white clover (Trifolium repens L., 2n=4x=32) and rhizomatous Caucasian clover (T. ambiguum M.Bieb, 2n=4x=32) have been produced. A backcross 2 (BC2) generation with white clover as the recurrent parent combines the growth habit of both parent species with the objective of increasing the persistency of large leaved T. repens varieties under grazing. T. ambiguum is more drought tolerant than T. repens. The drought tolerance of the hybrids in comparison with the parental species was compared in deep soil bins over a four week drought cycle. Soil moisture content, leaf relative water content …

The objectives of this study were to evaluate the leucaena (Leucaena leucocephala) performance and to select the best genotypes, based on yield,.stability parameters, and quality parameters. Annual leucaena yields were obtained by cuts over the rainy and dry seasons. A combined analysis of variance for yield, and quality parameters was performed. Also stability parameters and coeficients of determination were estimated. The combined ANOVA for edible dry matter yield and for acid detergent fiber, and digestibility revealed a significant difference for genotypes, environments, genotypes x environments, row spacings, cutting frequencies, and cutting heights, Six genotypes of leucaena were selected …

Forage Quality, Yield And Palatability Of Quackgrass (Elytrigia Repens (L.) Nevski), T. Yagi, R. Meguro, E. Fukuda
IGC Proceedings (1977-2023)
Quackgrass (Elytrigia repens (L.) Nevski) is a competitive perennial invader of pastures and hay meadows which is frequently harvested as forage in mixtures with desired forage species. Field experiments were conducted to compare quackgrass with cool-season perennial grasses grown under the same soil and climatic conditions, in terms of forage quality, productivity, and palatability. The forage quality of the hays was influenced by the grass species. Quackgrass showed forage crude protein (CP) concentration that was equal to those of perennial ryegrass (Lolium perenne), reed canarygrass (Phalaris arundinacea) and Kentucky bluegrass (Poa pratensis), and …

IGC Proceedings (1977-2023)
Amaranth (Amaranthus spp.) may have potential as a forage for summer grazing in the southeastern United States (US). Six accessions of amaranth were harvested at bud stage in two successive growing seasons to evaluate growth characteristics, yield, and forage quality parameters. The accessions, three genotypes of A. tricolor (Hinchoy VL, RRC-701, RRC-1186) and one each of A. hybridus (RRC-843), A. cruentus (RRC-1034), and A. dubius (RRC-1186) were evaluated in 1994 and 1995 on a Dothan sandy loam (fine loamy, siliceous, thermic, Plinthic Paleudult) soil at the Fort Valley State University Research Station, Fort Valley, Georgia. The plots were planted …

IGC Proceedings (1977-2023)
From 1995 until 1999 a trial was done in the fields of the Universidad Nacional de Córdoba with four C4 forage grasses. These fields lie in the subtropical and semiarid region of Argentina. This research aimed to identify forage species that could be used as deferred forage for the drier and cooler winter season. Four species of C4 grasses were used: Rhodesgrass (Chloris gayana Kunth), Gatton (Panicum maximum), coloratum (Panicum coloratum) and digitgrass (Digitaria eriantha), respectively. Two growing periods were used: full season growth (FS) and half season regrowth (HS), in both cases …
Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
IGC Proceedings (1977-2023)
Winter forage availability in Sudan is constrained by lack of a suitable annual winter forage crop. The main forage crop grown is Abu70 (Sorghum bicolor) which is a summer crop that yields 7.6-8.4 t/ha in summer but much less in winter. There is, therefore, need for a winter high yielding forage crop that exceeds Abu70 in productivity and quality. This study was aimed to evaluate four forage maize cultivars as potential winter crops in central Sudan in terms of productivity and quality. An experiment was conducted using four maize forage cultivars. The experiment lasted for two consecutive seasons …

Since 1982 Embrapa Beef Catle in Campo Grande, MS, Brazil, develops a Panicum maximum Jacq. breeding program, based on the germplasm collected and assembled by IRD (Institut de Recherche pour le Developpment) and received through a cooperation-agreement with IRD. The germplasm was evaluated and four cultivars were released directly from the germplasm: cultivars Tanzania, Mombaça, Massai and BRS Zuri. Breeding began in 1990 and involved crosses between sexual plants and selected apomictic accessions. The program consists of evaluation followed by selection of hybrids in plots with replications, evaluation of the selected hybrids in national network experiments in diverse regions and …

Resistance To Drought In Shore Elurope (Aeluropus Litoralis) And Weeping Alkaligrass (Puccinellia Distans), Mohammad Jafari, A. G. Firouzabadi
IGC Proceedings (1977-2023)
Two rangeland grass species, Shore Elurope (Aeluropus litoralis) and Weeping Alkaligrass (Puccinellia distans) were studied. The research was done under a split plot experiment and completely randomized design. Plants were grown under two irrigation treatments (seven and fourteen day periods of irrigation treatments). Morphological response included determination of wilting percentage, leaf water potential, production of yield, root dry weight, weight ratio of root/stem and finally total dry weight of species. Anatomical studies included leaf descriptive structure such as comparison of stomata and their density in area unit, study of vascular structure, mesophyl tissues and epiderm. Results …

Phenotypic Plasticity Of Diverse Sorghum Varieties In Response To Nitrogen Deficit Stress, Mackenzie Zwiener
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The movement of nutrients from old vegetative tissue to young leaves and reproductive organs is known as senescence. Senescence can be influenced by the environment of a plant, such as, drought, heat, and nutrient stress. These environmental stressors can also influence canopy architecture. Crop canopy consists of several traits including: leaf number, angle, length and width. Past research in crops like maize and rice have shown significant influences of more erect leaves, including, the ability for increased planting density, which optimizes light interception and increases yield. In a field trial of a sorghum association panel including 345 different sorghum varieties …

Background: Improving grain yield in cereals especially in wheat is a main objective for plant breeders. One of the main constrains for improving this trait is the G × E interaction (GEI) which affects the performance of wheat genotypes in different environments. Selecting high yielding genotypes that can be used for a target set of environments is needed. Phenotypic selection can be misleading due to the environmental conditions. Incorporating information from phenotypic and genomic analyses can be useful in selecting the higher yielding genotypes for a group of environments. Results: A set of 270 F3:6 wheat genotypes in the …
