Morphological and Agronomic Attributes of Some Local and Modern Aromatic Rice Varieties of Bangladesh

摘要

The study was conducted in order to investigation the relationship between grain yield with the morphological parameters of five local and three modern aromatic rice varieties. The varieties Kataribhog, Radhunipagal, Chinigura, Badshabhog, Kalizera, BRRI dhan34, BRRI dhan dhan37 and BRR1 dhan38 were transplanted. All the parameters varied significantly in different aromatic rice varieties. Among the aromatic rice varieties the highest grain yield was obtained from BRRI dhan34 which identically followed by Kataribhog. The highest plant height was observed in Chinigura which statistically similar to Kataribhog The highest number of fertile tillers hill~(-1) was observed in BRRI dhan37 and it was identically followed by Radhunipagal, Badshabhog, Chinigura, BRRI dhan38 and the lowest fertile tillers hill~(-1) was obtained from Kalizera which was statistically similar to Kataribhog. The highest number of grains panicle~(-1) was found in BRRI dhan34 and that was the lowest in BRRI dhan38. Maximum 1000 grain weight was observed in BRRI dhan38. In respect of yield BRRI dhan34 and Kataribhog are suitable for Dinajpur region in Bangladesh during T. aman season.
