The common bean is a tropical facultative short day legume that is now grown in tropical and temperate zones. This observation underscores how domestication and modern breeding can change the adaptive phenology of a species. A key adaptive trait is the optimal timing of the transition from the ve...

Crossbreeding parameters and variance components were estimated for lactation and reproductive traits of crosses between the Sahiwal, Brown Swiss and Ayrshire breeds in a dairy herd in sub-humid coastal Kenya. An individual animal model was fitted to the data with a fixed effect for 20 distinct b...

Investigates the effects of non genetic factors on performance, and estimates genetic parameters of reproductive and productive traits with a view to examining the appropriateness of the assumed parameters. Presents an evaluation of a long-term breeding programme in a closed Sahiwal herd in Keny...

The value of intra- and interracial populations in common bean (Phaseolus vulgaris L.) needs to be determined in order to create useful genetic variation for maximizing gains from selection, broadening the genetic base of commercial cultivars, and making efficient use of available resources. Five...

Maize (Zea mays L.) is an important staple food crop in West and Central Africa(WCA). However, its production is constrained by drought. Knowledge andunderstanding of the genetics of hybrid performance under drought is invaluablein designing breeding strategies for improving maize yield. One hund...

The amount of genotypic and phenotypic variability that exists in a species is important for selection and initiating breeding programs. Yam bean is grown locally in tropical countries of the Americas and Asia for their tasty storage roots, which usually have low dry matter content. The crop was ...

Plant breeders need to quantify additive and non-additive components of genetic variance in order to determine appropriate selection methods to improve quantitative characteristics. Hierarchical and factorial mating designs (also known as North Carolina mating designs I and II, respectively) allo...
