The genetic material for the study comprised of three F₂  populations (Vaishak x Vyttila 6, Vaishak x Harsha and Thottacheera x Harsha) and their parents (Vaishak, Thottacheera, Vyttila 6 and Harsha). In the experiment  the genotypes were raised in the field under rainfed upland condition exposed to natural stress. The characters studied were days to 50% flowering, nature of panicle exsertion, leaf rolling score, plant height at maturity (cm), number of productive tillers plantˉ¹, number of filled grains panicleˉ¹, spikelet sterility(%), 1000 grain weight(g), grain yield plantˉ¹(g), straw yield plantˉ¹(g) and harvest index(%). Based on the mean performance of the genotypes, the F₂ segregants, Vaishak x Harsha  and the parents, Vaishak and  Vyttila 6 performed well under upland condition. The correlation analysis revealed that among parents, there was significant positive correlation for number of filled grains panilceˉ¹ and 1000 grain weight with grain yield plantˉ¹ whereas  in F₂ populations, grain yield plantˉ¹ was positively correlated with number of filled grains panicleˉ¹, 1000 grain weight and harvest index. In both the cases spikelet  sterility(%) recorded a significant negative correlation with grain yield    plant^-1.
