Path analysis studies of Dolichos bean (Lablab purpureus L.) genotypes

Abstract

An investigation entitled “Path analysis studies of Dolichos bean (Lablab purpureus L.) genotypes” 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 study revealed that number of pods per vine exhibited high positive direct effect on pod yield per hectare followed by average weight of 10 pods, pod setting percent, length of inflorescence, vine length. The association between pod yield and these characters was significant. The direct negative effects on pod yield observed by pod length, number of pods per inflorescence, number of grains per pod, pod width, days to first flowering, days to 50% flowering and days to first picking.
