摘      要：: The high-molecular-weight glutenin subunit (HMW-GS) components from about 85 varieties were fractionated by SDS-PAGE, including 22 corner stone breeding parents, 45 varieties taking important role in Chinese wheat production and 18 varieties with good bread making quality. The 22 corner stone breeding lines carry either null (c) or l(a) summits on Glu-Al loci. Five types are detected on Glu-Bl, which are 7 + 8(b), 7 + 9 (c), 14 + 15 (h), 17 + 18 (i), 6 + 8 (d). 7 + 8 and 7 + 9 are the two major types. Six types have been detected on Glu-Dl, which are 2 + 12 (a), 2 + 10 (e), 5 + 10 (d), 4 + 10 (j), 4 + 12 (c), 2 + 11 (g). 2 + 12 and 2 + 11 are the two major types. In the corner stone breeding lines, early premium from American carries 5 + 10, St2422/464 from Italy carries the 14 + 15. In addition, two relatively essential varieties, Mara and Alondra carry 5 + 10. In the 45 commercialized varieties, sowed more than 666 000 ha (10 million mu) annually, only Yangmai 5 conveys the 5 + 10 on Glu-Dl, and Xiaoyan 6 and Yumai 7 carry the 14 + 15 on Glu-B1. Four varieties, Funo, Nongda 139, Zhengzhou 683 and Fan 6 convey the 17 + 18 on Glu-B1. The 18 bread wheat varieties recommended by the Ministry of Agriculture in 1992 could be classified into two groups, 5 + 10 and 14 + 15. Zhongzuo 8131 and its selections are the typical genotype of 5 + 10. Genes coding the two subunits are from either Yecora F-70 or IRN68-181. Xiaoyan 6 and its derivative varieties are the typical genotype of 14 + 15. The genes coding 17 + 18 subunits in Chinese varieties were derived from Funo or its selections. These results basically reflect allelic changes on Glu-1 in Chinese wheat varieties in the past 50 years. It is also proven that HMW-GS components may have great diversity between lines from the same cross, which causes great difference on baking quality.
