title: [Identification of Sorghum genes responsible for resistance to Green bug].
abstract: 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.
