Correlation studies in different genotypes of dolichos bean (Lablab purpureus L.)

Abstract

The present investigation entitled “Correlation Studies in different genotypes of Dolichos bean (Lablab purpureus L.)” was carried out during 2017-18 for 9 different sowing dates at All India Coordinated Research Project on Vegetable Crops, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra. The experiment was laid out in Randomized Block Design (R.B.D.) with ten pole type genotypes and three replication. The results of the present investigation clearly showed that pod setting percent, number of pods per vine, number of pods per inflorescence, vine length, pod length, length of inflorescence, number of grains per pod and pod width significantly positive association with green pod yield. Also days to first flowering, days to 50% flowering and days to first picking showed significantly negative association with green pod yield. The association between characters revealed in the present study shall be of great help to choose genotypes with desirable characters for hybridization, selection and further breeding program.
