Identification of Sorghum genes responsible for resistance to Green bug

Genes responsible for resistance to greenbug (Schizaphis graminum Rond.) were identified in sorghum. The dominant (Sgr1) and recessive (Sgr2) genes for resistance were revealed in sample k-457 (PI264453, United States). The samples i-589430 (PI264453, Spain) and k-3852 (Sarvasi, Hungary) carry gene Sgr1. These accessions are assumed to also have gene Sgr2. The samples k-9921 (Shallu, United States) and k-9922 (KS-30, United States) have incompletely dominant resistance gene Sgr3. A symbol Sgr4 was assigned to the dominant gene from sample k-6694 (Deer, United States). The dominant Sgr5 and recessive Sgr6 genes were revealed in the samples k-1362 (Durra Belaya, Syria) and k-1240 (Dzhugara Belaya, China). The cultivar Sorgogradskoe (k-9436, Rostovskaya oblast) has gene Sgr5. The samples k-10092 (Odesskii 360, Ukraine) and k-5091 (Cherhata, Marocco) are assumed to have genes Sgr5 and Sgr6. Sample k-924 (Dzhugara Belaya, China) is protected by the dominant gene Srg7 and recessive gene Sgr8. Sample k-923 (Dzhugara Belaya, China) has at least one of these genes. Two dominant complementary genes for resistance (Sgr9 and Sgr10) were revealed in sample k-930 (Dzhugara Belaya, China). One of two dominant genes of sample k-1237 (Dzhugara Belaya, China) was assigned the symbol Sgr11. Genes Sgr5-Sgr11 responsible for resistance to greenbug are new and were not previously used in breeding.
