During 2007-2009 ys in the conditions of artificial infection 39 hybrids of F1, as well as their parental: 5 lines – restorers of pollen fertility as males and 9 lines – as females were studied on damage degree caused by phomopsis agent. Trials of sunflower hybrids were carried out on the isolated phytopathologic site in the 3 year monoculture conditions.
As a result of 3-year trials under the conditions of artificial infectious background of illness high donor characteristics as to a low degree of damage caused by the phomopsis agent in the line – a paternal form of semi-sib hybrids of sunflower Kh 843 R, Kh 1228 R and maternal forms of НС 26 А and SKh 2122 A werw revealed. The reliably high indexes of breeding value are established in the resistance paternal line Kh 526 R and maternal line – SKh 2111 A, and also receptive – paternal form Kh 843 R and maternal НС 26 А аnd SKh 2122 A
