Abstract:
... Cowpea is an important legume in sub-Saharan Africa where its protein rich grains are consumed. Insect pests constitute a major constraint to cowpea production. Flower bud thrips (FTh) is the first major pest of cowpea at the reproductive stage and if not controlled with insecticides is capable of reducing grain yield significantly. Information on the inheritance of resistance to FTh is required t ...

Gossypium hirsutum; cotton; germplasm; plant genetic resources; quantitative trait loci; flowering; phenology; phenotypic variation; branches; plant development; hybrids; crossing; plant breeding; cultivars
Abstract:
... Flowering time has biological and agricultural significance for crops. In Upland cotton (Gossypium hirsutum L.), photoperiodic sensitivity is a major obstacle in the utilization of primitive accessions in breeding programs. Quantitative trait loci (QTLs) analysis was conducted in two F₂ populations from the crosses between a day-neutral cultivar Deltapine 61 (DPL61) and two photoperiod sensitive G ...

Gossypium hirsutum; cotton; plant breeding; cultivars; breeding lines; crossing; hybrids; lint cotton; fiber quality; genetic variance; agronomic traits
Abstract:
... Selecting high yielding upland cotton, Gossypium hirsutum L. lines with improved fiber quality is a primary breeding goal. A diverse set of ten cultivars and one breeding line were crossed in a half diallel. Parents and F₂ hybrids were grown in three environments at Mississippi State, MS. Ten agronomic and fiber traits were analyzed by a mixed linear model approach based on the additive-dominance ...

crop quality; hybrids; plant breeding; general combining ability; crossing; diallel analysis; yield components; additive gene effects; peppers; Capsicum baccatum; specific combining ability
Abstract:
... The aim of this work was to estimate the general and specific combining ability of peppers by measuring fruit quality and yield traits. This experiment was carried out on the garden field from Universidade Federal de Viçosa (UFV), Minas Gerais State--Brazil. Eight lines of Capsicum baccatum belonging to the UFV Horticultural Germplasm Bank were chosen based on their broad genetic and phenotypical ...
