7 parents and 21 F1 were analysed for combining ability during the Kharif2018 for days to 50% flowering, days to maturity, plant height, branches per plant, number of pods per plant, number of seeds per pod, pod length, seed yield per plant, harvest index, biological yield per plant, test weight and protein content. Among them INDIRA URD PRATHAM was observed as the best general combiner on the basis to GCA effects for most of the traits and TU-103 as early maturing and dwarf stature. TU-103 x LBG-623, Indira Urd Pratham x LBG-623 and Indira Urd Pratham x TU-94-2 was observed as the best hybrids for yield per plant on the basis of SCA effects. | Combining ability studies in blackgram (Vigna mungo (L.)
