Abstract: Common bean (Phaseolus vulgaris L.) is one of the most important legume crops in the tropics of Latin America, Asia, and Africa including Ethiopia as a cheap source of protein. Information on the genetic variability and the interrelationship between yield and yield related traits are important for developing high-yielding crop varieties with valuable yield attributes. The current study was carried out with two sets of experiments, i.e un-inoculated and inoculated with one rhizobial...
Abstract: Finger millet is an important cereal crop with high genetic potential in Ethiopia. However, its production was challenged due to limited genetic information and availability of high- yielding and adaptable varieties. The main objectives of this study were to assess the genetic variability, heritability, genetic advance, and associations among yield and yield related traits including the direct and indirect effects of yield-related traits on grain yield. Sixty four finger millet acc...
Abstract: Sorghum is one of the most important cereal crops grown in the world for human consumption, animal feed and bio-energy. Biotic and abiotic stresses are the most dominant constraints for the production and productivity of the crop. The study was conducted with the objectives of estimating water use efficiency, drought tolerance and grain yield of sorghum genotypes under stress condition. The trials were conducted using 64 sorghum genotypes using Latin square design with two replicat...
Abstract: In West Hararghe, wheat is produced on thousands of hectares, but the productivity is much lower than the average of national and regional states due to moisture stress resulting from xv erratic rainfall. Developing varieties in the area is one of the measures to improve the production and productivity of wheat. This pre-breeding research was conducted to assess the genetic variability in bread wheat genotypes and determine the association among traits. Sixty-four genotypes includi...
Abstract: Sorghum is an important cereal crop grown primarily in arid and semi-arid climates with a wide range of adaptability to various agro-ecological conditions of Ethiopia. However, the limited availability of improved varieties and the low production potential of landraces have constrained sorghum production in Ethiopia and a little information is available on combining ability, heterosis, and gene action for locally adapted sorghum landraces. Therefore, the research was undertaken to ...
Abstract: Sorghum is an important food crop that is consumed by millions of people as a staple food source in arid and semi-arid areas of the developing world, especially Africa. It withstands hot and dry conditions better than most cultivated crops in Ethiopia. Sorghum is the most important crop for food security in Ethiopia's harsh conditions, where other food crops are difficult to grow. The experiment was conducted at Fedis Agricultural Research Center on station in 2022/23 main cropping...
Abstract: Potato is one of the important crops in Ethiopia and there is a favourable condition to produce than other African countries. but the production is low because of long dormancy periods which leads to delayed planting, poor crop emergence and vigour and limited availability of planting materials. Thus, this research was conducted to estimate the effect of tuber sizes, GA3 concentration and soaking time on dormancy breaking and sprouting characteristics. Additionally, the effect of B...
Abstract: Chickpea is one of most important pulse crops in Ethiopia. Despite its significance, the national average chickpea yield is low due to many constraints of which the unavailability of improved varieties for each growing and potential area. This research was conducted to evaluate genetic variability, association of traits, and determine the direct and indirect effects of traits on yield of chickpea genotypes. It was conducted at Bule Hora during 2022/23 cropping season that 36 Desi t...
Abstract: Common bean has a wide range of genetic diversity for various economical traits and possesses broad variation in terms of cultivation methods, range of adaptation to environments, and morphology. Knowledge of both morphological and molecular diversity of the crop is important in plant breeding for selecting superior genotypes for yield and other agronomic traits to utilize as parents in crossing programs. The present study was carried out to characterize the common bean cultivars i...
Abstract: Finger millet is an important cereal crop in Ethiopia; however, the production of the crop is not at its genetic potential due to a number of production challenges, such as the lack of high yielding varieties and limited genetic information. Thus, the main objectives of this study were to assess the genetic variability, heritability, genetic advance, and association among yield and yield-related traits, as well as the direct and indirect effects of yield-related traits on grain yie...
Abstract: Hararghe coffee improvement both for yield and quality is vital for the sustainability of its production and fetches premium prices in world market, but limited information on genetic variability and association of morpho-agronomic and bean quality traits of Hararghe coffee collections. This research was conducted to assess genetic variability and determine the associations among morpho-agronomic and bean quality traits in Hararghe coffee collections. Sixty-four collections evaluat...
Abstract: Sorghum is the fifth most important cereal crop in the world. It serves as a staple food for millions in Africa and Asia. Ethiopia is the centre of origin and diversity for this crop. Ethiopia is endowed with diverse genetic resources for sorghum. Many studies were done elsewhere on Ethiopian sorghum genotypes; none of them provides the nutritional profile of rich Ethiopian sorghum germplasm. The aims of this study were to estimate the genetic variability of sorghum genotypes for y...
Abstract: The study of genetic variability is the critical step in crop improvement programs either to use the natural variation that already exists or produce genetic variation. This study was conducted to assess the genetic variability of 20 bread wheat genotypes and determine associations among yield, yield related traits and protein content. The experiment was laid out in randomized complete block design with three replications during 2017 at Raare research site of Haramaya University. T...
Abstract: Bread wheat variety development is vital to improve the productivity and product quality in Ethiopia which could be achieved by the information generated from the pre-breeding activity. Thus, this research was conducted to assess the genetic variability among bread wheat genotypes for quantitative and grain quality traits, estimate association of traits and determine the direct and indirect effect of traits on grain yield. The experiment was laid out in 10 x 10 simple lattice desig...
Abstract: The study of genetic variability for key agro-morphological traits is crucial in sorghum breeding. Although, the national sorghum improvement programs have released a number of sorghum varieties for the highland areas of Ethiopia, the production and productivity is still low as compared to global potential (6 ton/ha ). Huge amount of sorghum germplasm exists in the country, but a little information is available on genetic variability, heritability and genetic advance for the studie...
