A total of 52 progenies in F5 generation derived from an interspecific cross between greengram (Vigna radiata cv. VBN(Gg)2) and blackgram (Vigna mungo cv. Mash 114) were subjected to correlation and path analysis. Based on the results of the present study, it can be concluded that number of pods per plant recorded significant and positive association with seed yield per plant. This trait alone recorded high direct effect on seed yield per plant. It also had moderate to high indirect effect for other traits. Hence number of pods per plant can be given top most priority while framing selection strategy for improvement of seed yield in interspecific derivatives of Vigna radiata x Vigna mungo.
