Abstract
An experiment was conducted at
farmer's field at Dinajpur of Bangladesh to evaluate the yield
performance of three hybrid rice varieties (BRAC-777, BRAC-444,
Heeradhan-19) and three conventional modern high yielding
(BRRIdhan-28, BRRIdhan-58 and BRRIdhan-63) rice varieties. The trial
was made by transplanting seedlings of winter rice (boro rice) during
2016-17 (boro season). It is revealed that the hybrids and
conventional modern rice varieties differed significantly among
themselves in respect to different plant parameters. On an average
highest yield (8.32 t ha-1) was obtained from hybrid BRAC-777, while
among the conventional modern rice, the highest yield (6.20 t ha-1)
was obtained from BRRIdhan-63. Straw yield was found to be higher in
hybrid rice Heeradhan-19 (10.61 t/ha) which was much higher than the
conventional ones. Higher values in yield contributing characters,
such as number of effective tillers/panicle, filled grain/panicle,
1000 grain weight and days to maturity were observed in hybrid rice
as compared to those in the modern ones. Conversely, panicle length
was higher in modern varieties.
Keywords: Rice varieties, hybrid
rice, modern rice and rice production.
