Abstract:
In the greenhouse,twenty-eight wheat materials belonging to commercial cuitivars of Henan,(wheat selection in regional test and sources of resistance)were inocufated with nine cultures of Erysiphe graminis f.sp.tritici.The infection type information gained from this procedure was directly used to analyse the definitive genes of wheat varieties according to the principles and methods of interorganismal genetics.The results showed that different varieties carried different nurnbers of definitive genes.The way of incorporating definitive genes into susceptible varieties was discussed.
Key words:
Interorganismal genetics,
Definitive genotypes
