Soybean (Glycine max (L.) Merr.) is a leguminous and oil crop with rapidly growing importance demand in Africa following the increasing for livestock poultry feed sub-Saharan Africa. However, soybean productivity low most countries of Africa, especially West where below one ton per ha. Hence, concerted varietal development testing efforts have been underway by International Institute Tropical Agriculture (IITA), collaborating various African US-based breeding programs. Integrating new...
Understanding the genetic structure and diversity of crops facilitates progress in plant breeding. A collection 270 bambara groundnut ( Vigna subterrenea L) landraces sourced from different geographical regions (Nigeria/Cameroon, West, Central, Southern East Africa) unknown origin (sourced United Kingdom) was used to assess diversity, relationship population using DArT SNP markers. The major allele frequency ranged 0.57 for 0.91 West Africa region. total gene (0.482) Shannon index (0.787)...
Soybean is a leguminous crop known for its multiple utilizations both as food and feed humans livestock. The objectives of the study were to identify high dry matter yielder stable genotypes across environments in southwestern Ethiopia. effect genotype environment (G x E) interaction on yield soybean evaluated two cropping seasons (2019-2020) under rain fed condition. Eight pre tested with checks used treatment randomized complete block design three replications. Collected data recorded...
Understanding the extent of genetic diversity is a pre-requisite in cassava breeding program due to its available broad base crop and have great opportunity for improvement. This study was designed assess 184 germplasm sourced from International Institute Tropical Agriculture (IITA) previous collection Jimma Agricultural Research Center (JARC) by using DArTSNPs markers. The data were subjected imputation filtering minor allele frequency 0.01, 0.95 major TASSEL Beagle. resultants 9,310...
Abstract Background Genome-wide association studies (GWAS) are important for the acceleration of crop improvement through knowledge marker-trait (MTA). This report used DArT SNP markers to successfully perform GWAS on agro-morphological traits using 270 bambara groundnut [ Vigna subterranea (L.) Verdc.] landraces sourced from diverse origins. The study aimed identify marker nine agronomic and their candidate genes. experiment was conducted at two different locations laid out in alpha lattice...
Ethiopia is one of the centers genetic diversity sesame (Sesamum indicum L.). The resources present in country should be explored for local, regional, and international improvement programs to design high-performing market-preferred varieties. This study’s objective was determine extent variation among 100 diverse cultivated germplasm collections using phenotypic traits simple sequence repeat (SSR) markers select distinct complementary genotypes breeding. One hundred entries were field...
Sesame (Sesamum indicum L.) is an important oilseed crop with well-developed value chains. It Ethiopia’s most valuable export commodity after coffee (Coffea arabica L.), contributing to socioeconomic development. The productivity of the low and stagnant in Ethiopia other major sesame growing regions sub-Saharan Africa (<0.6 t/ha) due a multitude production constraints. objective this study was document opportunities constraints, as well farmer- market-preferred varieties traits, eastern...
Abstract For grain yield stability analysis, genotype by environment interactions are crucial in properly identifying and discriminating between varieties locations. Hence, this experiment was conducted with the objectives to evaluate of soybean using additive main effects multiplicative interaction (AMMI), multi‐trait index (MTSI), weighted average absolute scores biplot (WAASB), Eberhart Russell regression model, plus (GGE) analysis for genotypes identified stable different agroecologies...
Background and Objective: Understanding the extent of genetic diversity among genotypes organizing individuals into groups whose members are similar in some ways have an immense importance plant breeding program.The objective this study was to estimate 36 upland rice based on quantitative morphological traits.Materials Methods: The field experiment conducted using 6×6 simple lattice design two locations southwestern Ethiopia (viz., Gojeb Guraferda) during 2016 main cropping season.Cluster...
Abstract Formal public sector soybean breeding in Africa spans over four decades, and it was initiated by the International Institute of Tropical Agricultural (IITA). As demand continues to outstrip production, strategic projects such Legume (TL) were initiated, which main goal enhance productivity farmers’ fields Sub‐Saharan Africa. One strategies is through developing deploying improved varieties target countries. Through TL I II projects, a number released countries, Kenya, Nigeria,...
Abstract African yam bean, AYB ( Sphenostylis stenocarpa ), is an underutilized legume of tropical Africa. can boost food and nutritional security in sub-Saharan Africa through its nutrient-rich seeds tubers. However, inadequate information on germplasm with desirable agro-morphological traits, including insufficient data at the genomic level, has prevented full exploitation breeding potentials. Notably, assessing genetic diversity population structure a species prerequisite for improvement...
Abstract Understanding the phenotypic variation and designing a mini‐core collection is an efficient method to accelerate genetic gain of bambara groundnut. A 300 groundnut landraces from 25 different countries origin sourced gene banks were used analyze variability among develop for future breeding. The evaluated in alpha lattice design with two replications 2 years (2019 2020). results showed highly significant differences ( p < 0.001) all studied traits implying selection better...

Soil acidity with associated low nutrient availability is one of the major constraints to soybean production in southwestern Ethiopia. Integrated use lime and acid-tolerant crops believed reduce soil improve crop production. The experiment was conducted field condition Mettu, Ethiopia during 2017/18 main cropping season. comprised fifteen genotypes two amendment (lime unlimed) treatments arranged a split-plot design three replications. For each treatment, four rows were planted per plot;...
