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.
