Abstract: Tef is one of the most important crops widely cultivated throughout Ethiopia as a staple cereal crop. Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methods to meet the diversified goals. Therefore, a field experiment was conducted to estimate genetic variability, associations of traits, and to determine the direct and indirect effects of yield components on grain yield of tef. The experiment was lai...
Abstract: Triticale varieties were recommended for production in Ethiopia following research undertaken for many decades. However, these varieties were not evaluated and introduced in districts of Benshangul Gumuz regional state having potential for the production of the crop. Therefore, the present research was undertaken to evaluate eight triticale varieties and assess the effect of locations and genotype x location interaction on yield and yield related traits, and to identify farmers’ ...
Abstract: The yield performance of maize genotypes is highly influenced by environmental factors and genotype by environment interaction (GEI). The presence of GEI makes it difficult to select the best performing as well as the most stable genotypes. Therefore, conducting multi-environment trials, appropriate analysis of the data and interpretation of the result is important to develop improved maize cultivars effectively in Ethiopia. This study was carried out to assess the effect of GEI on...
Abstract: Common bean is an important herbaceous annual grain legume in the world, chiefly grown as a source of protein, carbohydrates, vitamins and minerals in human diets. In Ethiopia, beyond promoting food, health and nutritional security, it covers the dominant part of the country’s pulses export contributing to the economy of the country.In an attempt to increase the productivity of the crop,several improved varieties have been released from national and regional research centers. How...
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 stress 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 alpha lattice design with two replicati...
Abstract: Ethiopia is the center of origin and domestication for sorghum with a wide range of sorghum collections for various agro-ecologies. However, there are many factors that hinder the production and productivity of sorghum. Drought is one of the most important factors that affect crop production worldwide and continues to be a challenge to plant breeders, despite many decades of research. Understanding the genetic variability and trait association is key to the development of improved ...
Abstract: Drought is among the most important obstacles in agriculture that retard the production as well as productivity of the crops across the entire world. Since sorghum is highly produced from arid to semi-arid tropics, it is one of the staple and strategic crops for farmers. However, there are a number of constraints that reduces production and productivity of sorghum in the country. Stay greenness resulting in higher grain per mass yield and lodging resistance to boost sorghum grain y...
Abstract: Potato (Solanum tuberosum L.) is one of the tuber crops produced in Ethiopia, mainly at mid and highlands of Ethiopia, due to the absence of potato varieties adaptable to lowland areas of the country. The country has large arable land in lowland areas, Thus, developing varieties adaptable to these areas is important. this research was conducted to estimate the effect of genotype x environment interaction (GEI) on morpho-agronomic traits and determine yield stability of potato genot...
Abstract: Mung bean is one of the most important legume crops. It serves as a source of protein for poor farmers in drought-prone areas of Ethiopia. It is used as a source of food and insurance crops during the drought season. Mung bean is adaptable to a wide range of climatic conditions. Despite adaptation and importance in moisture-stressed areas, its productivity is generally low due to a lack of suitable and drought-tolerant varieties. Moreover, the crop has got limited research attentio...
Abstract: It is imperative to study the level of genetic variability available in the existing groundnut genotypes due to the fact that, the aim of groundnut breeding programs across the world is to develop new varieties that meet the needs of growers, processors, consumers, and overall market demands. The present study was carried out to assess the extent of genetic variability among groundnut genotypes for agro-morphological and quality traits and to estimate association of traits and dete...
Abstract: Bread wheat is one of the most important cereal crop produced in almost all agro-ecologies of Ethiopia. Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methods of genotypes for further evaluation to meet the diversified goals.Therefore the field experiment was conducted to estimategenetic variability, association of traits, determining their direct and indirect effecton grain yield and to identify pri...
Abstract: Establishment of seedling growing method(s) is priority activity to the distribution of newly introduced vegetable crops. Chaya is proposed as candidate vegetable crop to distribute in eastern Ethiopia. However, recommendation is lacking for rooting media and type of cutting to produce seedlings. Therefore, this study was conducted to assess effect of rooting media and number of nodes on rooting, seedling establishment and early growth of chaya at Dire Dawa from February 2018 to Ju...
Abstract: Development of drought tolerant potato varieties for moisture stress areas is one of the strategic orientation and research priorities of the Ethiopian Potato Research Program. Estimation of variability is the first step in the process of variety development. This research was conducted at Simada research site of Adet Agricultural Research Center, a satellite site for drought experiments, in 2016 main rain season to estimate genetic variability, correlation among traits and to dete...
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...
