​Comparative Study of Crossability Behavior in Intra-specific and Inter-specific Crosses of Vigna radiata and Vigna mungo

Background: The basic plant material consisted of 9 mungbean and 5 urdbean genotypes. 42 different crosses were made comprising 13 Vigna radiata x V. radiata, 4 mungo 25 crosses. Varying degree success has been achieved in obtaining intraspecific interspecific having desired variability for yield contributing traits along with MYMV resistance. Methods: present investigation was done at Agricultural Research Farm, Banaras Hindu University, Varanasi, during Kharif, 2019 Summer, 2020. intra-specific inter-specific cross combinations initially examined their crossability. Out these, six promising higher crossability percent further analyzed hybrid pollen fertility, lethality and, evaluation F1 parents traits. Result: Crossability per cent found highest HUM 2 IPM 02-3 (41.86%) while, NDU 1 R3/12 (41.38%). In crosses, the maximum SKAU M 365 R3/28 (34.92%). Two genotypes (HUM 26) two (R3/12 R3/28) can be utilized genetic improvement through hybridization as there are better performing on basis attributes
