Abstract: Thirty six bread wheat genotypes were tested to assess the genetic variability and genetic diversity among genotypes using triple lattice design at Bena-Tsemay district Weyito Nasa Agricultural Farm in 2020 under irrigation condition. The analysis of variance revealed highly significant variation among the genotypes for days to heading, grain filling period, days to maturity, plant height, spike length, number of spikes, number of kernels, 1000 seed weight, and grain yield. Wide ra...
Abstract: Chickpea is an important pulse crop in Ethiopia; however, the production of the crop is not at its potential due to many constraints of which limited availability of high yielding varieties. Thus the main objectives of this study were to estimate genetic variability and assess associations of yield and yield related traits of chickpea genotypes. Forty nine kabuli chickpea genotypes were evaluated for 13 traits in 2019/20 at Arsi Robe using 7x 7 simple lattice designs with two repli...
Abstract: Finger millet is adaptability to adverse agro-ecological conditions with low input, tolerant to moisture stress and plays a significant role both as food grain and animal feed in areas where production of other cereals are reduced by marginal environments. The national and regional research centers recommended considerable numbers of varieties to varied agro- ecologies to increase the productivity of finger millet. Hence, it is necessary further evaluation of varieties for stabilit...

Abstract: Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methods and/or selection of genotypes for further evaluation to meet the diversified goals. Therefore, this field experiment was conducted to assess genetic variability for agronomic and grain quality traits and estimate the association among the traits, and to determine the direct and indirect effects of traits on grain yield of bread wheat genotypes. T...

Abstract: production. Therefore, the present study was conducted at Melkasa Agricultural Research Center, Meiso substation in 2018 main cropping season using 20 common bean accessions to estimate genetic variability and associations among yield and yield related traits. The experiment was laid out as randomized complete block design with three replications. Data were collected for 13 quantitative traits including plant height, number of primary branches, number of pods per plant, pod length,...
Abstract: Potato (Solanum tuberosum L.) is a highly heterozygous and has complex tetrasomic inheritance that make difficult to understand the inheritance of traits and implement in hybridization program. However, the genetic variation created in F1 generation could be exploited through asexual propagation. Research efforts carried out in Ethiopia related to improving potato through crossing were limited in scope of breeding works. Thus, this study was conducted at Adet in 2018 to assess the ...
Abstract: In Ethiopia, rice variety development program was started recently but many rice varieties were recommended for production. But recommendation of varieties and introduction of new genotypes alone might not be enough to increase rice yield. This required conducting a multi-location evaluation of varieties and identified wide to specific adaptable variety is critical steps in breeding. Therefore, this research was conducted to determine the effect of genotype (G), environment (E) and...
Abstract: The field experiment was conducted to assess the extent of genetic variability and traits associations in soybean genotypes for yield and its related traits and thereby generate information as well as identify superior genotypes for further improvement program. A total of thirty-six soybean genotypes were evaluated using simple lattice design at Fedis eastern Ethiopia during the 2018 cropping season. Data were recorded for major qualitative and quantitative traits and analyzed usin...
Abstract: Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methos.Keeping this in view, the present study was conducted to assess the genetic variability and character associations among yield and yield related traits in Ethiopian linseed genotypes.Fortiy nine linseed genotypess including four released varieties were evaluated in 7x7simple lattice design at Debre Berhan,North Shewa in 2018 main cropping season.T...
Abstract: Sorghum is one of the major staple food crops in eastern Ethiopia where the area is known with an uncertainty of rainfall. Therefore, this study was conducted to assess genetic variability among sorghum genotypes, and to estimate associations among yield and yield-related traits of sorghum genotypes. Thirty-four sorghum genotypes and two improved varities in 6x6 simple lattice designs at Fedis Agricultural Research Center in 2018 cropping season. Results of analysis of variance rev...
Abstract: Quality protein maize (QPM) is a type of maize whose nutritional value has been enhanced through conventional breeding. The production of hybrid QPM is started very recently in Ethiopia that requires extensive research to exploit heterosis to increase the productivity of the crop. Exploitation of heterosis through the production of hybrids is proven breeding method to improve the yield of maize. Accordingly, the objectives of this study were to estimate the magnitude of heterosis a...
Abstract: Genotype by environment interaction and yield stability analysis are important in measuring varietal stability and suitability for cultivation across seasons and different ecological zones. The genetic potential contained within the crop, the environmental effects and their interaction play a great role in determining the yield performance and stability of the crop to a given environment. Such kind of study was lucking at the study areas and the current study was conducted with the...
Abstract: The study was conducted at Haro Sabu Agricultural Research Centre (HSARC) during the 2015 main cropping season. The objectives of the study were to estimate combining ability and to identify direction and magnitude of standard heterosis in mid-altitude maize test crosses for grain yield and yield related traits. Eighteen inbred lines and four single cross testers were crossed in line x tester mating design during the 2014 main cropping season at Bako National Maize Research Center ...
