Evaluation of cowpea (<em>Vigna unguiculata</em> L. Walp) genotypes for yield and associated traits

Abstract

Twenty cowpea (Vigna unguiculata) genotypes were evaluated for thrip and aphid resistance and yield and associated traits. The associated parameters studied were Thrip score, aphid score, plant height, number of branches, number of clusters, number of pods, seeds per pod and yield and the result obtained showed significant differences . From the result obtain it can be concluded that GCP-400, GCP-387 and GCP-287 had the best results in most of the parameters evaluated.

Evaluation of Different Genotypes of Cowpea (Vigna unguiculata (L.) Walp.) for Growth and Pod Yield in Prayagraj Agro-climatic Conditions

“…To plan appropriate breeding programme and to evolve high-yielding cultivars with resistance to pests and diseases, the plant breeders must possess adequate knowledge of variability, character association patterns, the extent of contribution of each character to fruit yield and genetic variability [5][6][7]. As the information on the nature and magnitude of variability for yield other characters present in germplasm pool owing to genetic and non-genetic causes, is an important basic pre-requisite for starting any systematic breeding programme in identifying superior lines or varieties [8][9][10][11]. Being a legume, cowpea fixes atmospheric nitrogen.…”
