Assessment of salt tolerance and variability within some rice germplasm using microsatelittes
Soil salinity is a major abiotic stress that affects rice production. It can reduce yield drastically and result in total crop failure. The objectives of this study are to determine the genetic diversity within thirty-six rice accessions and to identify genotypes that are tolerant to salinity. Thirty-six rice accessions including three check varieties were sown in experimental pots and their leaves harvested for DNA...

Evaluation of agronomic performance of beta-carotene rich (yellow fleshed) cassava varieties in Nigeria
Twenty-five yellow fleshed cassava varieties including three checks (two improved and one local) were evaluated in a randomized complete block design with four replications in three locations in Nigeria. Tuber yield, dry matter content, root size, fiber content, harvest index, sprouting and vigor of the varieties evaluated were all significant at 0.05 significant levels across the locations. Taste, color of unexpanded...

Genetic variability, heritability and genetic advance of maize (Zea mays L.) inbred lines for yield and yield related traits in southwestern Ethiopia
Understanding the genetic variability, heritability and genetic advance of traits in any plant population is an important pre-requisite for breeding program. The experiment was conducted to assess the magnitude of genetic variability, heritability and genetic advance of 24 maize inbred lines for 16 quantitative traits. The field experiment was conducted during 2016 cropping season at Jimma Agricultural Research Center...

Correlation and path coefficient analysis of yield and quality components of garden cress (Lepidium sativum L.) genotypes in Ethiopia
The improvement for a trait of interest can be achieved by both direct and indirect selection of characters that are more heritable and easy to select. The aim of this study was to determine the degree and nature of associations among seed yield and seed quality related characters. One hundred eight garden cress (Lepidium sativum L.) genotypes were evaluated for their yield and seed quality related traits using a...

Genetic variability of some chickpea (Cicer arietinum L.) genotypes and correlation among yield and related traits in humid tropics of southern Ethiopia
The current investigation evaluated the genetic variability of some chickpea (Cicer arietinum L.) genotypes and correlation among yield and related traits in Abaya Woreda. Five improved chickpea genotypes along with one local variety were laid out in randomized complete block design with three replications. Data were recorded from phenological, growth parameters; and yield and related traits depicted the ranges of mean...
