A wide variation was observed in amylopectin contain,ranging from 54. 47% to 69. 26%,while amylose content ranged from 11. 26% to 23. 22%. The average crude fat in all cultivates was 3. 46%,and most cultivates ranged from 3. 1% to 3. 7%. Protein contents ranged from 8. 61% to 15. 54% with a mean value of 11. 94%. For amino acid composition,the ten cultivates were particularly rich in leucine,and the mean was 34. 57 mg/g. The millet cultivars were also high in glycine,glutamic acid and cysteine. Millet was known to be limiting in the essential amino lysine,and the mean was 5. 18 mg/g. Other amino acids,tyrosine,histidine and arginine were also very low in the ten cultivars. In general,significant nutrient composition differences were observed between the different millet cultivars,and A2( a kind of mother line of the hybrid millet) and hybrid millet registered a higher level of protein and amino acid composition which would be useful in millet breeding.展开更多
