STUDY ON GENETIC VARIABILITY, CORRELATION AND PATH ANALYSIS OF DOLICHOS BEAN GERMPLASM OF TRIPURA

Abstract

Twenty-two landraces of Dolichos bean were collected from Tripura during 1988
and evaluated at Barapani Farm, CIAR Research Complex for NEH Region. A
wide range of genetic variability was recorded for all the characters. High
heritability accompanied by high genetic advances were recorded in pods/plant,
pod yield/plant and pods/panicle. Number of pods/plant. pod yield/plant and
panicles/plant were highly associated with pod yield and contributed maximum
indirectly via number of pods/plant, while number of pods/plant and single pod
weight contributed maximum, directly. Hence for the improvement of Dolichos
bean by selection, maximum emphasis should be given on these four characters
viz. pods/panicle, panicle/plant, pods/plant and single pod weight.
