Abstract:

The seed of Sorghum Apomixis Line 1094 and 2083 were treated by 0.3% EMS. Young plant were transplanted to field at 4-leaf period.To study on the affect of two Sorghum Apomixis Lines by EMS and create the germplasm. The results showed that two Sorghum Apomixis Lines were mutated to different degree by EMS treatment. Some mutants of plant height, panicle length, fertility and fruit ratio were selected in M0 evaluation. An averge of 2 years, the mutant rates of the plant height, the panicle length and the fertility are 0.66%, 1.03% and 1.93%.The mutant plants of the fruit ratio around 30%-40% were at most. Thus the technique has a great meaning in breeding practice and theoretical research.
