Description: Wheat microsatellite Xgwm261 was used to identify Rht8 dwarf gene in main Chinese wheat varieties released in the last 30 years. The results, supplemented by pedigree analysis, showed that 42.3 % of Chinese wheat varieties contained Rht8, but its frequency differed in different ecological zones. Combined with the results of GA3 test, it indicated that 20.6 % of Chinese wheat varieties carried both Rht8 and GA3 insensitive dwarf genes. For most Chinese wheat varieties, their Rht8 could be traced back to Funo, Villa Glory, St1472/506 and St2422/464 introduced from Italy, and Bezostaya1 from Russia. 1B/1R varieties, such as Avrora, Lovrin 10, Kavkas, Predgornia 2, etc, once widely used as the parents resistant to rust and powdery mildew in China, could also be the donors of Rht8.
