Gwas Revealed Effect Of Genotype × Environment Interactions For Grain Yield Of Nebraska Winter Wheat, Shamseldeen Eltaher, P Stephen Baenziger, Vikas Belamkar, Hamdy A. Emara, Ahmed A. Nower, Khaled F.M. Salem, Ahmad M. Alqudah, Ahmed Sallam

Department of Agronomy and Horticulture: Faculty Publications

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 F_3:6 wheat genotypes in the …

Improving Breeding Program Efficiency And Genetic Gain Through The Implementation Of Genomic Selection In Diverse Wheat Germplasm, Dylan Larkin

Graduate Theses and Dissertations

Genomic selection (GS) is an important tool for increasing genetic gain for economically important traits in breeding programs. Genomic selection uses molecular markers across the entire genome in order to predict the performance of breeding lines for a trait of interest prior to phenotyping. A training population (TP) of elite germplasm, representative of the University of Arkansas wheat breeding program, was developed in order to predict important agronomic and Fusarium head blight (FHB) resistance traits within the University of Arkansas wheat breeding program through cross-validation and forward prediction.

A genome-wide association study (GWAS) was performed on the TP to identify …

Integrated Management Of Aphis Craccivora In Cowpea Using Intercropping And Entomopathogenic Fungi Under Field Conditions, Allan Mweke, Komivi Senyo Akutse, Christian Ulrichs, Komi Kouma Mokpokpo Fiaboe, Nguya Kalemba Maniania, Sunday Ekesi

All Peer-Reviewed Publications

Cowpea aphid, Aphis craccivora, is a major cowpea pest. Cowpea–cereal intercrop alone does not effectively manage the pest. Use of pesticides in intercrop leads to health and environmental risks. Fungal-based biopesticides offer a better option because they are environment-and consumer-friendly. This study assessed the combined effect of Metarhizium anisopliae ICIPE 62 and cowpea–maize intercrop against A. craccivora under six treatments: (1) untreated cowpea monocrop, (2) untreated cowpea–maize intercrop, (3) cowpea monocrop + ICIPE 62, (4) cowpea–maize intercrop + ICIPE 62, (5) cowpea monocrop + Duduthrin insecticide, and (6) cowpea–maize intercrop + Duduthrin during three seasons (long rainy/cold and dry/short rainy). …

Farmers’ Knowledge, Attitudes And Practices (Kap) On Production Of African Indigenous Vegetables In Kenya, Donatien Ntawuruhunga, Hippolyte D. Affognon, Komi K.M. Fiaboe, Mary O. Abukutsa-Onyango, Losenge Turoop, Beatrice W. Muriithi

All Peer-Reviewed Publications

Local knowledge, attitudes, and practices (KAP) regarding African Indigenous Vegetables (AIVs) among local growers are required to design effective vegetable productivity-enhancing interventions. However, limited studies have been conducted in Kenya to assess the knowledge, attitudes, and practices on production performance of AIVs. A survey was conducted among 600 AIV growers in Busia, Nyamira and Machakos Counties of Kenya to assess the knowledge, attitudes and practices regarding AIVs and their contribution on output/yield. Primary data were collected using a semi-structured questionnaire supplemented with key informant interviews. Results showed significant knowledge and positive attitude of farmers regarding AIVs, but insignificant use of …

Selection Of Suitable Varieties Of Grasses For Myanmar, Nang Khan Hline, Khin San Mu, Moe Thida Htun, Lwin Naing Oo, Soe Min Thien, Dezin Soe Lwin, Jue Jue, Aung Aung, Jenny Hanks, Werner Stür, Ganda Nakamanee

IGC Proceedings (1977-2023)

The basal feed resources for ruminants available in most developing countries in the tropics are crop residues, pasture from infertile land, for example communal land, or agro-industrial by-products. These are low in protein and of low digestibility. A major problem facing livestock producers in tropical areas is proper nutrition for their animals during the dry season when pastures, cereal residues and maize stover are limiting in nutritional quality. The researchers in Myanmar have tried to improve the nutritive value of fibrous agricultural residues. Aung Aung et al. (2006) supplemented the sesame and chickpea husk to bulls fed on urea-treated …

Light Dependent Morpho-Physiological Changes And Yield Response Of Hybrid Napier Cultivars Under Rainfed System, Savitha Antony, C. George Thomas

IGC Proceedings (1977-2023)

For small dairy farmers in the tropics, open land for fodder cultivation is often limited because of the predominance of tree crops and paddies. Probably because of this limitation, to offset fodder supply for the livestock, growing fodder crops under tree crops such as coconut is a widely prevalent practice in the tropics. However, successful establishment and growth of most fodder crops especially high yielding types such as hybrid napier under shade depends on the amount of light available and the consequent morpho-physiological responses of the crops.

Biomass Of Grasses And Other Herbaceous Plants For Bioenergy Use, Žydrė Kadžiulienė, Lina Šarūnaitė, Vita Tilvikienė, Jonas Šlepetys, Zenonas Dabkevičius

IGC Proceedings (1977-2023)

Biomass supply for different uses, especially for bioenergy production, is becoming increasingly important. Independently of the purposes of biomass use, high yields per unit area and best possible quality need to be achieved. As a result, the selection of appropriate plant species is an important aspect. Cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and reed canary grass (Phalaris arundinacea L.) were investigated on a light loam (Cambisol) with a view to assessing the impact of nitrogen (N) and harvest time on biomass yield used for biogas. The biomass yield was influenced by cutting …

Effect Of Plant Spacing On Yield And Quality Of Leucaena Leucocephala Subsp., Wattanawan Srisomporn, Kharuthai Jantipbadee, Ganda Nakamanee, Sukanya Kampayae

IGC Proceedings (1977-2023)

Leucaena leucocephala (Lam.) de Wit commonly known as leucaena, is one of the most productive tree legumes available to tropical agriculture. Leucaena leucocephala subsp. glabrata 34/92 was introduced to Thailand from Oxford Forestry Institute in the year 1996 with another 16 lines and evaluated in Thailand. It was chosen as a potential psyllid resistance and high forage edible yield (Phaikaew et al., 2005). Seed lot 34/92 is derived from K636 through selfing (Hughes, 1993). This report is a part of ‘research and development of Leucaena leucocephala subsp. glabrata production as protein source in commercial feed project’ which contain a …

The Effect Of Tree Densities On The Biomass Of Leucaena Leucocephala And Chloris Gayana Using A Nelder Fan Design, Anibal Nahuel Alejandro Pachas, H. Max Shelton, Christopher J. Lambrides, Scott A. Dalzell, G. John Murtagh

IGC Proceedings (1977-2023)

Leucaena leucocephala-grass pastures are widely used for ruminant feeding in tropical and subtropical regions. In Australia, over 200,000 ha of leucaena grass pasture have been planted with more plantings expected as it is recognized as the most productive, profitable and sustainable feeding system (Shelton and Dalzell, 2007). Planting densities and planting configurations for the leucaena component vary, ranging from single or double leucaena hedgerows 3 to 12 m apart (Radrizzani et al., 2010). There is little information about how tree/grass planting configurations and resulting inter- and intraspecific competition affect above and below-ground interactions. We hypothesise that individual leucaena …
