Tianjin adzuki beans enjoy a long-standing reputation in the international market. Its rust is spread by air currents and is a major disease that seriously affects the yield of red bean. Major annual occurrence of serious or even cut the absolute yield is a major obstacle to the development of adzuki bean production. In order to find out the cause of the disease, the author conducted a survey on the occurrence of rust in the main producing areas of adzuki bean in Tianjin from 1985 to 1989. First, the factors that lead to the disease (a) breed. In 1987, when rust occurred, the results of the field disease resistance test showed that there were differences among the 11 cultivars tested for disease resistance. The incidence of different varieties
