Abstract:

This study used 34 core fresh soybean germplasm samples from Quzhou as experimental materials to conduct descriptive statistical analysis of oligosaccharide content and construct frequency distribution maps. To screen excellent fresh soybean oligosaccharide varieties, the analytic hierarchy process (AHP) was used to construct an evaluation system for fresh soybean oligosaccharide germplasm resources from the selected indexes, combined with correlation analysis and stepwise regression analysis. The results showed that the coefficient of variation of sucrose, stachyose, raffinose, and oligosaccharides content was below 11.00%, with a small degree of dispersion. These four indicators followed a normal distribution, yet the distribution of sucrose content had a certain negative bias, and there were a small number of extreme values in oligosaccharide content. By AHP method, the 16 selected indexes were classfied into agronomic traits, yield traits and quality traits. Among them, the yield trats exhibited the highest weight of 0.443 4, and was followed by quality traits (0.387 4) and agronomic traits (0.169 2). Within the 16 selected indexes, the oligosaccharides content showed the highest weight of 0.171 8, which was followed by sucrose content, hundred-grain fresh weight, effecttive branching number and each pod grain number. Based on the the final score, the test materials were divided into four levels, with Level Ⅰ consisting of 0715F1, 0513I2, 0716F1, 1213B3, 1007C2, and Quxian No.1. Among them, 0715F1 had the highest agronomic traits score and yield traits score of 0.596 6 and 1.451 4, respectively, and 1007C2 had the highest quality traits score of 1.407 3. This study combined the analysis of soybean quality traits, agronomic traits and yield traits, providing a screening basis for obtaining new soybean varieties with optimized oligosaccharide quality structure through hybrid breeding.
