Genetic variability studies on yield and yield contributing traits in blackgram (Vigna mungo (L.) Hepper

An experiment was conducted to estimate the genetic variability on twenty-eight genotypes of blackgram (seven parents and twenty-one F1’s) during kharif- 2017 in RBD at Research cum Instructional Farm, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. Variability was studied for twelve quantitative characters. From the present investigation it was found that all the characters showed significant variation for all the traits except for days to 50% flowering. GCV and PCV estimates were observed high for seed yield per plant followed by biological yield per plant and plant height.
