Abstract
The purpose of this study was to improve the genetic quality of several types of legumes of the genus Vigna through inter-species hybridization. The ultimate goal of this activity is to obtain a new superior variety of hybrid vegetable pea which contains high protein and anthocyanin, is tolerant to drought and has high production. This research was conducted for two years. The activities of the first year are: 1). Back crosses between superior hybridized species and their two parents, 2). Evaluation of all existing genotypes and selection of superior individuals in the F2 population. Data were analyzed by analysis of diversity, LSD, estimation of narrow and broad meaning heritability, correlation analysis of both genotypic and phenotypic, and determining the success rate of crosses. The results of this study are: 1). Several hybrids resulting from crosses between cowpea and long bean species have the potential to be developed into superior varieties containing high protein and anthocyanins, 2). By backcrossing superior hybrids with their two parents and continuing the selection, there is an improvement in genetic quality. 3). All observed variables had narrow and broad categories of heritability, except flowering age which had high heritability and number of seeds per plant had low heritability. 4). The number of pods per plant has a significant positive correlation with yield so that it can be used as a selection criterion for yield improvement.
