Cultural morphology and vegetative compatibility of Cytospora chrysosperma isolates;

Study on vegetative compatibility and anastomosis group in Botrytis cinerea Pers;

Induced nitrate non-utilizing mutants of Botrytis cinerea and their use in vegetative compatibility tests;

Effect of heteroallelism at each vegetative incompatibility(vic)locus on transmission of hypovirus in Cryphonectria parasitica was characterized.

Study on vegetative compatibility among isolates of Paecilomyces cicadae(Miquel)Samson;

In order to Jingyang strain is the highest aggressiveness strain which come from the area of Shaanxi Guanzhong, We studies on Pathogenicity and vegetative compatibility tests for the strains of Verticillium dahliae to exp.

dahliae and to provide the theoretical testimony for establishing disease control techniques,the pathogenicity, biological cultural character- istics,ISSR molecular analysis,vegetative compatibility and fungus toxin of strains of V.

vasinfectum collected from Shache county, Xinjiang was tested to be 100,while the CI between them and each of the other three forma specialises was 0, which belong to different vegetative compatibility groups(VCGs).

Studies on the vegetative compatibility of pathogenic Fusarium oxysporum:;

Twenty strains of Fusarium oxysporum isolated from cucumber,melon and watermelon were grouped into vegetative compatibility groups(VCGs)by using nitrate nonutilizing(nit)mutants,and dif-ferent percentages of chlorate resistant mutant and nit mutant obtained from different hosts,positions of the plant and pathogenicity were observed.
