Abstract: Malt barley (Hordeum vulgare L.) is one of the most important industrial crop and highly demanded due to the expansion of brewery factories in the country and the unique nature of the grain for malt. However, its production and productivity is very low compared to other countries due to limited numbers of high yielding malt barley varieties, partial use of agro-nomic and production and low genetic base in north eastern Ethiopia. The objectives of this study were to assess the genet...
Abstract: The cultivated sesame (Sesamum indicum L) is an annual plant of the Pedaliaceae family and is considered as one of the oldest crops cultivated by man, having been grown in the Near East and Africa for over 5,000 years for cooking and medicinal needs. Among the major oil crops grown in Ethiopia, sesame seed has a unique position mainly due to its adaptation to arid and semi-arid low land environments. Yet, the insufficient genetic information of Ethiopian sesame populations hinder t...
Abstract: Wheat is one of the major cereal crops produced in Amhara Regional State. However, productivity of wheat in the region, particularly in Wollo is low due to various production constraints. Several improved bread wheat varieties were developed and released from federal and regional research centers. Information on genotype by environment (GE) interaction and yield stability of recently released bread wheat varieties under the conditions of Wollo were scanty. Hence, this experiment wa...
Abstract: Micronutrient malnutrition has becomes the most serious challenge of humanity and most commonly lacking in human diets are Fe and Zn. Biofortification sustainably can reduce deficiencies by increasing Fe and Zn in staple foods. Genotype × Environment interaction (GEI) indicates differential reaction of genotypes to changes in environmental conditions; it becomes more important as the differences in production environment become diverse. Thus, this study was conducted to analyze GE...
Abstract: Sorghum is one of the major staple food crops grown in the poorest and most food insecure regions of Ethiopia. It is typically produced under adverse conditions, such as low input use and marginal lands. Its production is mainly constrained by the prevalence of drought; that is, the soil water deficit during grain filling stage of sorghum is considered among the major causes of grain yield loss for sorghum production in the dryland of Ethiopia. Factorial combination of treatments (...
Abstract: Chickpea (Cicer arietinum L.) is among the major pulse crops in Ethiopia. Despite of its importance the national productivity is low as compared to the potential of chickpea. As first step for the improvement of the crop, this study was conducted to assess the genetic variability and to estimate the association of traits, and determine the direct and indirect effects of yield related traits on yield of kabuli chickpea genotypes. Twenty five chickpea genotypes were evaluated in 5 x ...
Abstract: The highlands of Bale is known with potato production, but the productivity of the crop is low due to the growing of low yielding genotypes susceptible to late blight. This needs to develop varieties with high yield and resistant to late blight. Therefore, this study was conducted to evaluate 24 potato genotypes with the objective of assessing the nature and magnitude of variability for tuber yield, yield related and late blight resistance traits, and association of tuber yield wit...
Abstract: In plant breeding programs knowledge of nature and magnitude of variation existing in available plant breeding materials, interrelationships between quantitatively inherited plant traits and their direct and indirect effects on grain yield is of great importance. To generate such objectives, a field experiment was conducted in 2014 cropping season at Ofla district, Northern Ethiopia. 26 bread wheat genotypes were used in Randomized Complete Block Design with three replications for ...
Abstract: Cowpea [Vigna unguiculata (L.) Walp] is the world’s most important protein source where it is grown for forage, green pods, and grains. Stability performance of cowpea genotypes across contrasting environments is essential for the successful selection of stable and high yielding genotypes. Genotype by environment interaction is one of the leading factors that disturb the stability of genotypes. Therefore, this study was conducted to estimate the effects of genotype, environment, ...
Abstract: This study was conducted to assess the genetic variation of 100 durum wheat genotypes under water logging condition, determine associations among agro morphology and quality traits of durum wheat, and also to assess the degree of genetic diversity among the genotypes. The experiment was laid out in 10 x 10 simple lattice design during 2017cropping season at Debre Zeit and Chefe Donsa research sites. The analysis of variance showed that mean squares due to genotype and location by g...
Abstract: Durum wheat is one of the most important cereal crops in Ethiopia. The national average productivity and quality of durum wheat is low due to lack of improved varieties and dif erent biotic and abiotic constraints prevailing in the country these calls for development of improved durum wheat varieties. Knowledge on extent of genetic variability and identification of important characters and their interrelationship is a prerequisite for the development of high yielding and quality du...
Abstract: Information on combining ability and heterosis of maize (Zea mays L.) inbred lines is essential to maximize their use for variety development. This study was conducted to estimate general and specific combining ability effects of maize inbred lines and estimate the amount of standard heterosis of the hybrids for yield and yield-related traits. Eight maize inbred lines were mated through a half diallel mating design (Griffing’s Method IV, Model I). The resulting twenty-eight F1 hy...
Abstract: Breeding efforts to convert elite mid-altitude normal maize inbred lines to quality protein maize (QPM) has a recent history in Ethiopia. For a successful QPM hybrid and synthetic variety development, generation of information on heterosis, and combining abilities of newly developed QPM inbred lines is necessary. Accordingly, this study was conducted to estimate the combining ability of QPM inbred lines for grain yield and yield related traits, to estimate the magnitudes of heteros...
Abstract: Ethiopian potato (Plectranthus edulis) is an indigenous, underutilized tuber crop which has received very little attention in research, development, conservation, production and utiliza-tion. Considering the immense potential of biotechnological methods for conservation and im-provement of Ethiopian potato, the present study was designed to develop in vitro protocols for plant regeneration and somatic embryogenesis as well as to assess its genetic diversity. The study was conducted...
Abstract: Sesame is an annual oilseed plant, and indigenous, as evidenced with the presence of wild relatives, to Ethiopia. Despite immense economic importance and genetic resource, the report related to agronomical important traits is limited to very few populations. Thus, the current study was conducted to assess the genetic variability and association in yield, yield related traits and oil content of 36 Ethiopian sesame genotypes. The study was conducted at Babile and Dire Dawa, eastern E...
