Abstract:
A field experiment was conducted during summer season 2020 at research farm of ZARS Sindewahi. The experiment was carried out in Randomized Block Design (RBD) with seven rice genotypes viz., SYE-1, SKL-6, KJT-184, PDKV-Akshad, PKV-Makrand, RTN-5 and PKV-Ganesh. The data was recorded on the basis of different biochemical parameters at 30, 60 and 90 DAT. Highest reducing sugar observed in SYE-1 (2.25%) and lowest reducing sugar in PKV- Ganesh (2.04%). Highest non-reducing sugar observed in genotype SYE-1 (13.33%) which indicated that genotype SYE-1 found better for soft and moderate sticky rice grain for summer cultivation and said to be heat stress tolerant one. KJT-184 (10.68%) is found susceptible for heat stress. The highest amylose content (AC) observed in RTN-5 (24.59%) and lowest AC in SKL-6 (20.96%) and PKV-Makrand (22.04%). For good cooking quality, all of the genotypes of rice were soft but relatively sticky for cooked rice based on amylose content. The reducing, non-reducing sugar and amylose content were moderate to adequate in range due to high temperature. RTN-5 was superior due to its cooking quality parameters, for summer cultivation.
