PERFORMANCE, VARIABILITY, CORRELATION AND COHERITABILITY ESTIMATES IN RAJMASH

Abstract

Thirteen genotypes of rajmash (Phaseolus vulgaris L.) were assessed for variability, correlation and coheritability for yield and its attributes. The investigation revealed that among the genotypes PDR 90-18 was the highest yielder. The variability in days to flowering and pod length appeared mainly due to genotypic differences. High heritability estimates were recorded for days to flowering, pod length and seeds/pod. Additive gene effects were important in inheritance of days to flowering and seeds/pod, while nonadditive gene effects were important for remaining traits. Yield/plant showed high positive correlations with seeds/pod. Pod length and seeds/pod had higher coheritability with yield.
