AMYLOSE, AMYLOPECTIN, VOLUME EXPANSION RATIO AND KERNEL ELONGATION RATIO OF RICE LAND RACES IN BANGLADESH (Pages : 1 - 3)

Rice is the staple food and leading cereal crop in Bangladesh which is cooked and consumed as whole grain. Coking quality is directly related to the physical and chemical characteristics of the starch in the endosperm. Amylose, amylopectin, volume expansion ratio and kernel expansion ratio were determined of 36 land races and a high yielding variety BRRI dhan48 of Bangladesh to give an idea to the consumers of the cooking quality of the land races they consume and help breeders for development of better quality rice. The results revealed that amylose and amylopectin of the rice land races ranged from 15.92 to 24.34 and 75.66 to 86.72%, respectively. Amylose content was the highest in Basmoti sufaid and the lowest in Jara dhan. On the other hand, Tilokkachori showed the highest amylopectin and Basmoti sufaid had the lowest. Volume expansion ratio and kernel expansion ratio of the rice land races ranged from 1.37 to 2.28 and 1.09 to 1.54, respectively. Kataribhog showed the highest volume expansion ratio and Lal sora-2 showed the least. Whereas, BRRI dhan48 had the highest kernel elongation ratio and Lal sora-1 had the lowest.Download
