Estimation of genetic variability in red gram advanced breeding lines

Pigeon pea (Cajanus cajan (L.) Millsp) is the major pulse crop in India having 24-25% protein in the grain. To meet the protein requirement of growing population increased production is required. It is very difficult to increase the area under cultivation and hence new varieties are required which can yield better and also early duration varieties are required which fit into the cropping system. Hence, the present research was under taken including early duration variety to study the variability at Agricultural Research Station, Vizianagaram, Andhra Pradesh during Kharif, 2018. High variability was recorded for grain yield indicating ample variation which can be further exploited. Grain yield also recorded high heritability coupled with high GAM indicating preponderance of additive gene action. Days to 50% flowering also recorded high heritability and high GAM and these two traits are highly and significantly associated in positive direction. High yielding varieties are more expected in late maturing varieties, however, LRG 274 which is an early duration variety can be utilized in future breeding to develop early maturing high yielding varieties.
