Abstract:

The study aims to identify suitable growing environment for improving the nutritional quality and tasting quality of millet grain based on the existing millet varieties. The nutritional quality and tasting quality of ‘Changnong No.38’, ‘Changnong No.39’ and ‘Changnong No.41’ millet grains were analyzed. The results showed that the millet growing area had a greater effect on vitamin B1, amylose, crude protein of ‘Changnong No.38’ millet grains, vitamin B1 and crude fat of ‘Changnong No.41’ millet grains, and the coefficient of variation was above 10%; the growing area had little effect on the nutritional quality of ‘Changnong No.39’ millet grains, and the coefficient of variation was below 10%. It can be seen from the comparison of the tasting quality that the consistency of millet grains planted in Qinxian was higher than that in Changzhi; the consistency of ‘Changnong No.39’ and ‘Changnong No.41’ millet grains in Changzhi were lower than that of Qinxian; the grain color of ‘Changnong No.38’ and ‘Changnong No.39’ millet planted in Changzhi were superior to that in Qinxian, and the grain color of ‘Changnong No.41’ millet planted in Changzhi was the same as that in Qinxian. The total scores of the tasting quality of the three genotypes of millet planted in Qinxian were higher than those in Changzhi. Therefore, it is of significance to improve the quality of millet grains by optimizing the management measures of millet cultivation.
