Abstract:
Ten rice genotypes were evaluated with two check varieties for association studies of yield and its contributing traits to select the traits for yield improvement in upland condition. The experiment was laid out in randomized block design with three replications at research farm of upland Paddy Research Scheme, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif 2021. Twelve morpho-physiological characters or yield contributing traits like plant height, number of tillers, days to flowering and maturity, number of panicles, panicle length etc., were evaluated for correlation studies in twelve promising rice genotypes. Significant and positive association was observed between grain yield and its yield-contributing traits like plant height and Number of tillers. This association indicates increase in one or more of these traits results in an increase in grain yield. Hence, due consideration should be given to the traits while selecting rice genotypes. Among the ten genotypes studied genotypes viz. PBNR 14-07 and PBNR 14-11 recorded better performance and these are considered as the superior genotypes.
