Abstract: Thirty six field pea genotypes were evaluated at two locations in the central highlands of Ethiopia during the 2014 main cropping seasons. The objective of the study was to determine the magnitude of genetic variability and association of characters for yield and yield related traits. The study was conducted using a randomized complete block design with three replications. Data were collected on 15 quantitative traits and subjected to the analysis of variance, correlation and Mahal...
Abstract: Assessing the causes and magnitude of variation is the key to success in crop improvement program. This study was therefore conducted to study the genetic variability and association among yield and yield related traits of [Ipomoea batatas (L.) Lam] accession from East and West Hararge. Accession were planted in 10/4/2020 at Haramaya University Hirna research center, Eastern Ethiopia using Randomized Complete Block Design with three replication and evaluated for 12 agro-morphologic...
Abstract: Twenty five maize (Zea mays L) genotypes were evaluated in randomized complete block design for genetic variability and association between agronomic traits at Haramaya University at Chiro campus. Data were collected on 20 quantitative traits. The analysis of variance showed that the mean squares due to genotype were highly significant (p
Abstract: Sesame (Sesamum indicum L.) is considered to be an ancient oil seed crop to generate high quality edible oil having nutritional and health related value but still at an early stage in breeding. Its chromosome number is 2n=26 and it belongs to the Pedaliaceae family and having significant economic value globally as well as in Ethiopia.With the objective of broadening the gene pool of sesame an experiment was conducted in the genetics and molecular biology laboratory as well as agric...
Abstract: Chickpea (Cicer arietinum L.) is a mulit important legumes in Ethiopia; however, despite of all the multi benefits of chickpea, its productivity has remained low in Ethiopian agriculture than the attainable yield (5 tons/ha) under improved and good management condition. Reasonable seed yield in chickpea could be achieved by using improved genotypes with appropriate agronomic practices. The investigation of improved genotypes requires a good breeding program, which usually depends o...
Abstract: Black cumin (Nigella sativa L.) is an annual spice used for flavoring of food, cosmetics and other industrial products, besides oleoresins and essential oils are valuable sources for health care used for medicinal purposes in Ethiopia. However, variety development was started recently and mainly dependent on introduction of breeding materials. As first step for the improvement of the crop, this study was conducted to assess the genetic variability and to estimate the association of...
Abstract: Okra is considered a minor crop and has not given research attention in Ethiopia. Therefore, a key strategy to adapt to a changing climate is the development and promotion of underutilised crop species. Thus, this research was conducted to assess the genetic diversity, genetic variability, heritability, genetic advance and association of traits of okra genotypes using morpho-agronomic traits and biochemical contents. A total of 36 okra genotypes (27 landraces and 9 introduced comme...
Abstract: Potato is one of most important food crops in the world in general and Ethiopia in particular. However, low productivity of potato is one of the major constraints in potato production in Ethiopia. Encouraging adoption and wider diffusion of potato technologies are important policy measure to address the problem. However, adoption and intensity of adoption of improved potato varieties are constrained by many factors. Hence, in this study an effort was made to evaluate adoption decis...
Abstract: Evaluation of genotypes for the existence of variations and generation of genetic information is the key step in plant breeding to develop varieties for the targeted area of production. Twenty desi chickpea genotypes were tested in randomized complete block design with three replications. The objectives of the study were to estimate the extent of genotypic and phenotypic variability, estimate the genotypic and phenotypic associations among characters and to estimate the direct and ...
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: Sugarcane production affected by numerous factors, which subsequently reduce cane and sugar yield. Among those constraints, planting geometry is the most important one. To solve the problem, regarding intra-row setts spacing, research findings should be taken. However, research outputs concerning this aspect are not available at Kessem Sugar Estate. Therefore, effects of intra-row setts spacing on selected traits were carried out at this Estate with the objective of determining the...
ABSTRACT Low soil nitrogen (N) is one of the most important constraints to maize production in subSaharan Africa (SSA) in general and in particular the Bimodal Humid Forest Zone (BHFZ) of Cameroon. The development and adoption of maize varieties tolerant to low N soils could reduce the need for nitrogen inputs and significantly contribute to sustainable maize production. The objectives of this research were to: i) identify maize production constraints and farmers preferred maize characteris...
ABSTRACT Coffee ranks second after petroleum in international trade. In Kenya, it supports over 600,000 households, contributes up to12% of export revenue and employs 30% of the total workforce in Agriculture. Arabica (Coffea arabica L.) and Robusta (Coffea canephora Pierre) are the two species under commercial cultivation. Arabica coffee has low genetic diversity and susceptible to Coffee Berry Disease (CBD) and Coffee Leaf Rust (CLR) while Robusta Coffee has considerable diversity and tole...
ABSTRACT Soybean production in Kenya is estimated at 9,061MT. This is low compared to the annual demand of 100,000MT. This large deficit is met through importation which puts a strain to the economy’s foreign exchange. Soybean has the highest protein content (40-42%) among the food crops with oil content of18-22% comprised of 85% unsaturated fatty acids. These attributes make it an inexpensive source of proteins and desirable human diet. Released soybean varieties in Kenya have been evaluat...
ABSTRACT In Kenya, the counties of Elgeyo-Marakwet, Uasin-Gishu and Baringo, where maize, wheat and barley are normally grown, can be used to produce a second crop during the off-season (October-February) before the next cropping season or as a rotation crop during the main season (April-August). Introduction of drought tolerant leguminous crops such as chickpea in these counties is ideal in order to provide an alternative source of income to farmers. However Ascochyta blight (AB) disease whi...
