Genetic variability studies in blackgram
Author(s): A Kavitha Reddy, M Shanthi Priya, D Mohan Reddy and B Ravindra Reddy
Abstract: Genetic variability analysis was carried out for yield, yield components and water use efficiency characters in 30 blackgram genotypes. The study indicated existence of considerable amount of variability for all the characters. High heritability estimates were recorded for relative water content, SLA at 50 DAS, number of pods per plant, plant height, days to 50% flowering, seed yield per plant and number of clusters per plant. Number of clusters per plant, number of pods per plant, seed yield per plant and number of primary branches per plant exhibited high genetic advance as percent of mean. High heritability coupled with high genetic advance as percent of mean was recorded for number of pods per plant, seed yield per plant and number of clusters per plant indicating preponderance of additive gene action. Therefore, selection for the above traits would be more rewarding to bring improvement in black gram.
