The experiment was carried out to explore correlation and path coefficient analysis in two F2 populations of rice derived from the cross AD 16019 x ADT43 and AD16019 x WGL 14377 at TRRI, Aduthurai during 2016-18. In both the crosses single plant yield shows positive association with 1000 grain weight, plant height, number of productive tillers, panicle length. In the cross AD 16019 x ADT43 1000 grain weight and number of productive tillers per plant showed high direct positive effect on single plant yield and in the cross AD16019 x WGL 14377 only 1000 grain weight had high positive direct effect on single plant yield. Hence, selection of positively associated characters could bring improvement in yield and component characters.
