Abstract: In order to explore the nodule number characteristics of Adzuki Bean with rhizobium in field condition, found that the difference from nodule numbers of nodule bacteria in Adzuki Beans. Using 65 red adzuki beans as the research object, acquisition data in field and analysis its by computer. The results showed that in different traits of adzuki beans nodule number showed larger differences, creeping type red adzuki beans nodule number mean higher than the upright type 23.97; range higher than the value of 32.3. Among the characters correlation analysis showed the number of Adzuki Bean nodulation between with plant height and branch numbers of main stem and number of pods per plant and grains per plant showed extremely significant positive correlation, the correlation coefficient were 0.663325, 0.410746, 0.438036, 0.283786; the node number showed a significant positive correlation with correlation coefficient of 0.137257; the single pod length and 100 grain weight showed negative correlation, correlation coefficient were -0.08542, -0.3913 and 100 grain weight related reached extremely significant level. Different ecological types of Adzuki Bean nodulation number difference, breeders can use these differences to achieve the purpose of innovation germplasm.
