谷子起源于中国,在我国具有悠久的栽培历史。目前我国谷子栽培面积仅次于水稻、小麦、玉米而占第四位,播种面积约7,000万亩。据测定,小米中脂肪含量高于大米,白面,蛋白质含量和面粉接近。然而其品种间的营养品质有很大差异,因此,摸清谷子种质资源,提高小米的营养品质,显得十分重要。试验材料及方法 Millet originated in China, in our country has a long history of cultivation. At present, the area of ​​millet cultivation in our country is second only to that of rice, wheat and corn, with the sown area of ​​about 70 million mu. According to the determination of millet fat content is higher than rice, flour, protein content and flour close. However, the nutritional quality of its varieties are very different, therefore, find out the germplasm resources of millet to improve the nutritional quality of millet, it is very important.
