Abstract
Five exotic rice genotypes including one check BRRI
dhan39 were evaluated for the performance of growth and yield parameter during transplanted
Aman season 2012 in BARDC, Gazipur, Bangladesh.
The exotic genotypes were CNI9012, GSR IRRI I 2, OM576, Thai03 and Thai011.
Experiment results showed the significant differences on growth and yield
contributing parameters among the varieties. The yield of OM576 (5.81 t ha-1) was higher
than the popular check BRRI dhan39 and the lowest grain yield was found in
Thai03. The highest yield was observed due to higher panicle number m-2
(443.3) and higher spikelet filling percentage. The growth duration of OM576 (101
days) was 17 days shorter than BRRI dhan39 (118 days). The result suggests that
the genotype could be recommended to release as new variety in Bangladesh for
increasing rice yield in Aman season.
