为了探索红小豆根瘤菌在大田中的结瘤数特性,发现不同生态类型红小豆根瘤菌结瘤数之间的差异,研究以65份不同生态类型的红小豆种质资源材料为研究对象,通过对其农艺性状及根瘤菌结瘤数大田采集,计算机数据分析,结果表明在不同性状的红小豆之间结瘤数表现出较大的差异,匍匐类型红小豆结瘤数均值高出直立类型23.97;极差高出值为32.3。通过各性状之间相关性分析结果显示:结瘤数和红小豆的株高、主茎分枝、单株结荚数,单株荚粒数表现出极显著正相关,相关系数分别为0.663325、0.410746、0.438036、0.283786;和主茎节数表现显著正相关相关系数为0.137257;与单荚长、百粒重表现负相关,相关系数分别为-0.08542、-0.3913和百粒重相关达极显著水平。通过试验研究得出由于不同生态类型的红小豆根瘤菌结瘤数存在的差异,育种工作者可以利用这些差异达到创新种质的目的。
In order to explore the nodulation characteristics of Rhizobium japonicum in the field and to find out the differences of the nodulation numbers of Rhizobium japonicum in different ecotypes, 65 different accessions of Adzuki bean germplasm resources were studied, The agronomic traits and rhizobium nodulation field collection, computer data analysis, the results showed that the number of nodules in different traits of adzuki beans showed a greater difference, the average number of creeping adzuki bean nodules upright type 23.97 ; Very high value is 32.3. The correlation analysis of the traits showed that the nodulation number showed extremely significant and positive correlation with the plant height, main stem branch, pod number per plant and pods per plant, the correlation coefficients were 0.663325, 0.410746, 0.438036 and 0.2883786 respectively. The positive correlation coefficient was 0.137257 with the number of main stems, negatively correlated with the length of pods and the performance of 100-grain weight. The correlation coefficients were -0.08542 and -0.3913, respectively. . Through the experimental study, it is concluded that due to the differences in the number of nodulation of Rhizobium japonicum in different ecotypes, breeding workers can make use of these differences to achieve the goal of innovation germplasm.
