IMMUNOLOGIC ASSESSMENT OF COLLECTION SAMPLES CALLISTEPHUS CHINENSIS L. NEES. AGAINST FUSARIUM OXYSPORUM SCHLECHT

According to the results of immunologic assessment of collection samples C. chinensis L. Ness we have found that genotypes have various resistance to Fusarium wilt though the mosrt numerous are practically stable (R+) – 44.3% group of samples, midstable (S/) and immune (R) – 24.9 and 23.3%, respectively, susceptible (S) – 5.3% and very susceptible (S+) – 2.2%. In terms of grade distribution of the samples the type of reaction to Fusarium wilt resistance was as follows: reed (R) – 20.2%, (R+) – 48.9%, (S/) – 23.4%, (S) – 5.3%, (S+) – 2.2%; transitional – (R) – 26.4%, (R+) – 47.2%, and (S/) – 26.4%. According to theresults of immunologic analysis of the samples we have suggested the ones of high stability characteristics "polygenic resistance" to be used for further selection for resistanct to Fusarium wilt
