Rice holds promise to meeting food demand and ensuring social stability in Ethiopia. However, the country demand for rice far exceeds its production, with 80% of the deficit being met through imports. Hence, identification and utilization of genetically diverse genotypes is essential for crop improvement programs to develop and deploy high yielding...

Wheat is an important crop for food security, providing a source of protein and energy for the growing population in Ethiopia. However, both biotic and abiotic factors limit national wheat productivity. The availability of genetically diverse wheat genotypes is crucial for developing new wheat varieties that are both high-yielding and resilient to...

Simultaneous occurrences of heat and drought stresses have a detrimental effect on growth, development and yield of maize. Heat and drought is expected to worsen maize yield losses under climate change. Selecting CDHS tolerant maize hybrids creates great opportunity for sustainable maize improvement in the tropics. The objective of current investig...

Garlic is a widely cultivated vegetable with both culinary and medicinal uses in Ethiopia. The analyses, focusing on various traits, help in identifying genotypes with high productivity and quality. Garlic reproduces solely vegetatively due to male and female sterility in its gametophytes. Its domestication originated from the wild species Allium l...

Genotype by environment (G × E) interaction obstructs breeding by persuading variations in genotype performance. The aim of the present study was to determine the stability and yield performance of Desi and Kabuli chickpea varieties at different agroecological regions of Ethiopia, using different stability parameters. The experiment was laid out in...

This trail was initiated to assess the rate of genetic gain achieved so far in Ethiopian chickpea improvement program to re-design an effective improvement strategy for the future activity. Twenty-eight Desi and Kabuli type chickpea varieties released in Ethiopia were included in this trail. As a result of simple linear regression analysis, the gen...

The productivity and production of chickpeas can be improved by using access-improved varieties that are suitable for the specific agroecology. However, the foundation for adopting new technology is participatory variety selection (PVS). Therefore, this study aimed to identify the best adaptively improved chickpea varieties in northwestern Ethiopia...

An experiment was carried out in Adet, Debre Zeit, and Fogera stations, with eight Desi and twelve Kabuli type chickpea varieties laid out in a randomized complete block design (RCBD) with three replications. Teketay and Geletu varieties of Desi type chickpea had the greatest combined mean grain yield values of 1803.6 kg/ha and 1608.9 kg/ha, respec...

Cotton (Gossypium spp.) is a soft, fluffy staple fibre that develops in a boll, or protective casing, around the seeds of cotton plants of the genus Gossypium in the mallow family Malvaceae. Arboreums are thought to be indigenous to India. G. herbaceum may have been introduced into western India from Arabia, Persia and Baluchistan, as well as race...

In Ethiopia, there is immense potential for the cultivation of cotton, considering its suitable agro-ecological zones and the presence of water. However, there is a significant disparity between the potential and the actual production when it comes to Ethiopia's share of global production. Limited availability of research and extension services, in...

To enhance sesame yield, it is important to utilize diverse parents in breeding programs and implement an effective selection procedure, which exploits the association of quantitative traits. Therefore, the objective of this experiment was to explore the correlation among quantitative traits and assess genetic variability and diversity using both q...

Availability of genetic variability among a certain crop population and knowledge of the genetic parameters of yield and yield-related traits are the key preconditions to enhance seed yield. Therefore, sixty-four sesame genotypes consisting of fifty-nine accessions and five varieties were assessed in order to evaluate sesame genotypes for yield and...

p>The knowledge of correlation and path coefficient analysis allow crop breeders to practice indirect selection to improve traits like grain yield which are complex in nature. The objectives of the present study were to measure association among yield and yield related traits and to identify important traits for indirect selection to improve faba b...

The knowledge of correlation and path coefficient analysis allow crop breeders to practice indirect selection to improve traits like grain yield which are complex in nature. The objectives of the present study were to measure association among yield and yield related traits and to identify important traits for indirect selection to improve faba bea...

Onion is one of the major cash crops and helps improve the livelihoods of smallholder farmers. Although genetically and morphologically different, seedlings of all released onion varieties are transplanted at the ages ranging from 40 to 50 days, which contributes to the low level of productivity in Ethiopia. Therefore, a field experiment was conduc...

Knowing the extent of genetic variability among and within barley accessions provide bases of selection for breeders. However, given the heterogeneous nature of the germplasm, genetic information about barley landraces stored in gene bank of Ethiopia is not well archived. Therefore, genetic diversity study was conducted among and within 20 barley a...

Knowledge on genetic variability in faba bean (Vicia faba L.) is crucial to enhance its production and productivity. However, there has been very limited information on variability of Ethiopian faba bean accessions. Therefore, the present study was conducted to evaluate the phenotypic and genotypic variability, heritability and genetic advance of y...

A study was conducted to determine the optimum seed rate and row spacing on Kekeba bread wheat seed yield and quality performance at Adet and Wonberema, Ethiopia. The study consists of field experiments that were conducted at Adet Research Center and Wonberema farmer’s field during the 2018 and 2019 cropping seasons, and laboratory experiments at t...

Background: Genetic gains made on crop improvement are important for breeders to develop new crop varieties. However, information on the hitherto genetic gains made in the improvement of finger millet is scant and no assessment of this trait has been done on improved finger millet varieties in Ethiopia. Objective: A field experiment was conducted t...

The field experiment was conducted during the rainy season of 2018 in Burie District to study effects of seedling types and their growth stages on phonological and vegetative growth parameters of transplanted maize (Zea mays L.). Two types of seedlings (bare rooted and poly bagged); five levels of seedling's growth stage (1, 2, 3, 4 and 5 true leaf...

The field experiment was conducted during the rainy season of 2018 in Burie district to evaluate the effect of types and growth stages of seedlings on yield and yield-related traits of transplanted maize (Zea mays L.). In the District, terminal moisture stress and grain yield loss become the common challenges in maize production. The experiment was...
