Abstract:
An experiment was conducted to study physiological functions, yield and yield contributing traits in rice genotypes to obtain the variation in yield and morpho-physiological parameters of rice genotypes at research farm Upland Paddy Research Scheme (UPRS), VNMKV, Parbhani during Kharif 2021. The experimental plot was laid out in a randomized block design with twelve rice genotypes and 3 replications. The rice genotypes showed significant variations in morpho-physiological parameters, yield attributes and biochemical traits. Among the twelve rice genotypes, PBNR 14-07 followed by PBNR 14-11 recorded maximum plant height, number of tillers, number of panicles, number of spikelets, 1000 grain weight, grain yield per hectare, and harvest index, while minimum values varied among genotypes. There was no significant variation in panicle length among the rice genotypes. Maximum panicle length was recorded in genotype PBNR 14-07 followed by PBNR 14-11 and minimum panicle length was recorded in genotype PBNR 15-10. Highest chlorophyll content, Protein content, and carbohydrate content were recorded in PBNR 14-07 followed by PBNR 14-11.
