Abstract
Taking the gene-for-gene theory proposed by H.H. Flor as the theoretical basis and regarding the combination of parasite ans host (a phenomenon of antagonistic symbiosis) as the basic concept, W.Q. Loegering founded the science of inter-organismal genetics in 1966. Since this theory was established, it has been widely applied in studying rust-resistance of rice and other gramineous crops and many resistant genes have been found.
It has been tested by usual breeding procedure, but its application is limited only to the study of rice rust in the present study the principle and procedure of this theory are used to analyse the corresponding gene pairs of those watermelon varieties controlling anthracnose resistance and those isolates of Colletotrichum Lagenarium controlling pathogen ability and their own genotypes, so it will provide genetic information for collecting parents in watermelon breeding for resistance to anthracnose.
