Abstract:

The central region of Shanxi Province is very important for wheat production in this province.
Understanding genetic constitutions of these cultivars will provide useful information for wheat breeding. Using
SDS-PAGE and functional markers of five wheat genes, the high molecular weight glutenin subunits and
genetic constitutions of 10 major cultivars in the area were analyzed. The results showed that the 10 cultivars
included four types of HMW-GS combinations, of them, Jintai 9923 have a combination of 1, 7+8 and 5+10.
Analyzed with secalin and 1RS specific markers, four cultivars carried T1RS·1BL translocation. Three
cultivars carriedRht2 , 7 carriedRht8 , one carried bothRht2 andRht8 . Four cultivars carriedPinb-D1b , five
cultivars carriedPinb-D1a . Using PPO gene specific marker, three loci were revealed in the ten cultivars
indicating genetic polymorphism, of them, four cultivars carried the low active loci (The amplified fragment is
876 bp).
