Abstract: Dry seeds of two wheat cultivars were carried out for mutagenesis by satellite. The mutagenic effects of SP2 generation in agronomic traits were analyzed. The results showed that the variation of agronomic traits among cultivar was significant, while most variations in the lines were not significant. There were different mutagenic rate and the effects between cultivars. The mutagenic rate of the Yunong 201 was higher than the Dali 1. The variation of agronomic traits in the Yunong 201 were decreased while in the Dali 1 were increased. The mutagenic rate of plant height and grain weight was higher than the others.
