Nearly 100 000 accessions of germplasm resources of 15 different
food crops were evaulated for quality characteristics during
the period of the 7th, 8th, and 9th Five year plan in China. These crops include rice, wheat, barley, oats, buckwheat, corn, foxtail millet, broom millet, sorghum, faba bean, pea, mung bean, red bean, cowpea and common bean. Analysis on the verification data indicated that the quality trait indexes of all evaluated crops showed high variation. The variation range of crude protein, crude fat, lysine, total starch, amylose and amylopectin of most crops was described in this paper. So was the variation range of protein free extraction and saccharogenic power of some barley varieties, oleic aid and linoleic acid of oats, Vitamin E and niacin of buckwheat, oleic aid, linoleic acid and palmitic acid of maize, Vitamin B 1, Vitamin B 2 and Vitamin E of millet and tannin content of sorghum. Therefore, there are great potentialities for selection in the
germplasm resources available for good varieties and development of famous precious special foods. The good varieties with different uses are listed.
