Inoculation experiment on seedlings and pods of beans were carried out to have clear knowledge about the varietal resistance to the anthracnose caused by; Colletotrichum Lindemuthianum BRIOSI et CAVARA, using 44 varieties of native and foreign origins. Four strains of the causal fungus isolated from diseased pods of two varieties, Kintoki and Concord, and from affected seeds of Burma were used. The results of the inoculation experiments on seedlings showed that a number of varieties, namely, Kintoki, Tenashi-naga-uzura, Chunaga-uzura, Concord, etc., are susceptible and others such as Tenaslxi-chunaga-uzura, Kikuchi-naga-uzura, Tsunetomi-naga-uzura, Satisfaction, O-tebo, etc., are resistant. In spite of the general opinion that the pole bean varieties are resistant and the bush bean varieties are susceptible, the results of the present experiments showed that some of the pole bean varieties (Concord, Uzura) are susceptible and certain bush bean varieties (Tenashi-chunaga-uzura, Satisfaction, Beni-kintoki, etc.) are resistant. The results of the inoculation experiments on pods of six varieties whose resistances in the seedling's stage have already been graded, showed that there existed a parallelism between the seedling's resistance and that of pods.
