Abstract

The performance of five hybrid rice varieties namely Shakti 2, Suborna 8, Tia, Aloron and BRRI hybrid dhan 2 in Aman season was conducted and inbred BRRI dhan 33 was used as check variety. The result showed that the hybrid varieties exhibited superiority in respect of growth characters such as tillers hill-1, leaves hill-1, total dry matter (TMD) hill-1, leaf area hill-1, Leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) over the inbred. The highest TDM hill-1 (84.0 g), maximum leaf area hill-1 (1787cm2), average highest CGR and RGR (40.63 g m-2 d-1 and 17.9 mg g-1 d-1) were observed Tia and lowest TDM hill-1 (70.10 g), minimum leaf area hill-1 (1198cm2), average lowest CGR and RGR (27.26 g m-2 d-1 and 13.35 mg g-1 d-1) were observed in BRRI dhan 33. These hybrid varieties also showed higher yield attributes viz. effective tillers hill-1, 1000-grain weight, biological yield and harvest index (HI) over the inbred. The highest grain yield was achieved from Tia (7.82 t ha-1), which was closely followed by Shakti 2 (7.65 t ha-1). These two hybrid varieties produced 24.0% higher yield over the inbred BRRI dhan 33. Effective tillers hill-1 and higher filled grains panicle-1 mainly contributed to the higher grain yield of hybrid varieties.
