Molecular research in the tomato breeding for resistance to biotic stressors

An urgent problem in tomato breeding is the development of universal varieties and hybrids that combine high yields good fruit quality with group resistance to a number diseases. The purpose this study develop material resistant biotic stressors, basing on modern postgenomic technologies using molecular markers. At initial stage, we tested microsatellite markers from foreign literature sources, primers used were synthesized by Syntol LLC, samples collection FSBSI Federal Scientific Center for Biological Plant Protection Rice Centre studied under conditions Krasnodar region. PCR identifying target Ph -3 gene plant process optimized. Thus, our testing identify Ph-3 genetic material, selected 3 informative R2M1S, G8-1, R1-3U, which reveal allelic difference between susceptible samples.
