Identification of early maturing high yielding mutants in Black gram [Vigna Mungo (L.) Hepper]

Present study was carried out for identifying early maturing high yielding mutants in black gram [Vigna Mungo (L.) Hepper]” in a mutant population generated by using EMS, DMS and their post treatment with respective modifiers IAA and GA on in the background of black gram variety Barkha. The experiment was carried out in compact family block design during Kharif, 2005 at Experimental field of Department of Plant Breeding and Genetics, Rajasthan College of Agriculture, Udaipur. Use of EMS 0.4 + 3 x 10⁻³ M IAA induced early maturity with higher yield and also induced variability for other yield contributing traits. On the basis of yield parameters, eight progenies identified as high yielder and eighteen progenies were earlier in maturity than control. Genetic variability parameters viz., GCV, PCV, heritability and genetic advance exhibited high values for yield and yield contributing traits for family derived from use of 0.4% EMS 0.4 and DMS 0.04 with modifiers.
