dc.description.abstract The experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka,Bangladesh during the period from July to December 2017, to study the growth, development and yield of some local and high yielding rice varieties during aman season. Ten rice varieties were used as treatments; among them seven were local varieties (Kanchancni, Chinisagar, Sunashail, Ranjay, Lohadang, Haldijan, Kohabinni) and three were high yielding varieties (HYV) (BRRI dhan46, BR11 and BRRI dhan51).The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. There were significant difference among the data obtained from different growth, developmental and yield characters. At 25 and at 50 days after transplanting the highest plant height (62.21cm and 105.57cm respectively) was observed in Kanchancni. Highest plant height at 75 DAT (134.15cm) and at harvest (139.03cm) was found in Lohadang. Highest number of leaves hill 1 at 25 days after transplanting (26.00) was found in BRRI dhan46, at 50 DAT (56.67) and at 75 DAT (60.67) was found in Kohabinni, at harvest (34.87) in Ranjay . Highest number of tillers hill -1 at 25 DAT (6.67) was found in Ranjay, Haldijan, BRRI dhan46 respectively, at 50 DAT (16.33) was found highest in BRRI dhan46, at 75 DAT (11.64) was found highest in Sunashail, at harvest (25.00) was found highest in Kanchancni. Highest number of effective tiller (15.33) was found in BRRI dhan51, number of ineffective tiller (5.67) was found in Kanchancni and highest (17.67) total tiller was found in BRRI dhan51. Highest crop growth rate (54.86 g cm -2 day -1 ) and absolute grain growth rate (1.85 mg grain -1 day ) was found in Sunashail. Highest flag leaf area (56.20 m 2 ) was found in Lohadang. Pancle length (30.33 cm) was found highest in Haldijan, filled grain panicle -1 (113.67) was found highest in BRRI dhan46, unfilled grain panicle -1 (23.00) was found highest in Chinisagar, seed size (28.02 mg) was found highest in Haldijan, grain yield (3.62 tha -1 ) was found highest in BRRI dhan46, straw yield (4.17 tha -1 ) was found highest in Chinisagar, total biological yield (6.23 tha ) was found highest in Chinisagar, harvest index (59.73) was found highest in BRRI dhan46. Panicles hill -1 and filled grains panicle -1 mainly contributed to the higher grain yield of the high yielding varieties over the inbred. -1 -1 - en_US
