| Outline of Final Research Achievements |
We found polymorphism in amino acid sequence of soybean SEN1 genes. Nitrogen fixation activity of Lotus japonicus sen1 mutant transformed by Enrei SEN1 gene was slightly higher than that of Peking type SEN1 gene. Effect of polymorphism of soybean SEN1 gene on the soybean yield was analyzed using BC5F2 soybean plants prepared from crossing with Fukuyutaka (Peking type) and Enrei. As a result, 100-seed weight of Enrei type BC5F2 plants slightly higher than that of Peking type. These results show the possibility that Enrei type SEN1 gene have positive effect for soybean 100-seed weight due to higher nitrogen fixation in the nodules.
