Genetic analysis in Indian bean germplasm under Tripura agro-climatic conditions

Abstract

The Indian bean (Dolichos purpureas (L.) Sweet) is a popular leguminous vegetable grown in Tripura, a state in north eastern India. It is a self-pollinated crop but cross pollination (25-30%) has also been reported. Hence, there is a wide range of variation which aid in the selection of superior desirable land races (or) local varieties. Due to cross pollination and sexual propagation over long period of time, there is high degree of genetic diversity with in the species. The yield improvement in Indian bean can be achieved through selection of superior genotypes with desirable traits combination existing in nature. Hence, an attempt has been made to collect the available germplasm and evaluate them for yield and other genetic parameters.
