The present investigation was conducted at Zonal Research Station, (Birsa Agricultural University), Chianki, Palamau during Kharif. Thirty drought tolerant upland rice genotypes including two checks viz. Vandana and Anjali were laid out in the Randomized Block Design with three replications in rainfed upland situation. Data were recorded and analysed for ten yield attributing. A wide spectrum of variability was observed for all the characters under study. High genotypic coefficient of variation was exhibited for grain yield (19.84) followed by unfilled grain (18.36 and sterility % (15.94). High heritability estimates coupled with high genetic advance were observed for plant height and filled grains per panicle. The genotypic correlation coefficients were found to be higher than the corresponding phonotypic correlation coefficients. This indicated that there is strong inherent association between yield and its component traits. Plant height has negative correlation with yield indicating that taller rice plant have low yield. Grains per panicle, number of filled grains per panicle and test weight have positive and significant genotypic and phenotypic correlation with yield. Panicle length, numbers of grains per panicle, filled grain per panicle; test weight and harvest index contributed maximum direct or indirect effect on yield, indicating these traits should be given emphasis while selecting high yielding upland rice for western plateau of Jharkhand.
