In total, 179 predominant cultivars in recent 30 years and new breeder's lines from main ecological zones of China were examined by SDS-PAGE and SCAR for the presence of 1 BL/1 RS. On average, 30% of Chinese wheats released since 1980 contained 1 BL/1 RS, however, its frequency differed in different ecological zones, which was 59% for Northern Winter Wheat Zone, 42% for Yellow-Huai River Valley Winter Wheat Zone and 20% for both Middle and Low Valley of Yangtze River Winter Wheat Zone and Southwest Winter Wheat Zone. No 1 BL/1 RS cultivars were found in Northeast Spring Wheat Zone. The cultivars with high dough elasticity were generally not 1 BL/1 RS translocations. High molecular weight glutenin subunits (HMW-GS) may have some complementary effects on the quality defects caused by 1 BL/1 RS. From one point of view, 1 BL/1 RS parents are generally not recommended in breeding for medium to high dough elasticity, or one of the parents at least should not be 1BL/1 RS. Good combination of HMW-GS should be presented when 1BL/RS parent in used. The quality defects of 1 BL/1R should also be considered in soft wheat breeding.
