The field experiment conducted to evaluate the variation in morpho-physiological characteristics and yield contributing traits of different upland rice genotypes. This was conducted during Kharif 2023 at the Quality Seed Production Farm, Shendra ‘A’, Vasantrao Naik Marathwada Krishi Vidyapeeth (VNMKV), Parbhani, Maharashtra. The results revealed significant differences among the genotypes in terms of plant height, number of tillers, number of leaves, SPAD readings, grain yield and yield contributing traits.

The genotype PBNR 14-07 exhibited the maximum plant height, while PBNR 17-27 showed the minimum. Avishkar recorded the highest number of tillers per plant, followed by PBNR 14-07, whereas PBNR 12-13 had the least. The number of leaves per plant increased up to 60 DAS (days after sowing) and declined thereafter. Maximum leaves were recorded in PBNR 14-21, followed by PBNR 18-18, while PBNR 18-14 had the lowest. Grain yield per hectare was highest in PBNR 14-21, followed by PBNR 18-18, and lowest in PBNR 18-19. SPAD readings, indicative of chlorophyll content, varied significantly among the genotypes with Avishkar showing the highest readings and PBNR 18-15 the lowest.

Based on above results it is concluded that the genotype PBNR 14-21 and PBNR 18-18 had the best morpho-physiological performance for charater such as days to maturity, days to 50% flowering, length of panicle and yield per ha.
