Abstract
Antixenosis and antibiosis were evaluated in 3 somaclonal variants of wheat (Orof272) and barley (GP639-1 and GP760) with a low level of resistance to greenbug ( Schizaphis graminum ). All somaclones possessed both components of resistance to the pest. The resistance is supposed to be under polygenic control because of its very low expressiveness and constant segregation for the trait in several generations. Simultaneous antibiosis and antixenosis changes indicated evident pleiotropic effect of minor genes for the trait. Relationships between different mechanisms for plant resistance to insects are discussed
