摘　　要：开展选育大豆抗SCN3种质资源的创新及利用,有利于加快抗线大豆育种进程、缩短育种年限、增加农民收入;利用筛选和鉴定出的抗线大豆种质资源和优异的外引品种资源材料进行杂交、复合交时,基因发生重组、累加、互补与突变等遗传效应,对后代(F6)连续2年进行抗病鉴定分析,从中鉴定出抗SCN3的创新种质资源,并利用创新种质资源进行审定推广成为抗线大豆新品种,改良了遗传组成,拓宽了抗线大豆血缘,为今后抗SCN3育种工作奠定了基础。The innovation and use of soybean germplasm resource resistant to SCN3, will facilitate breeding process, shorten breeding duration, and increase farmers＇ income. Hybridization between soybean germplasm resistant to SCN and elite variety, using the genetic effects of hybrid composite cross-recombination, cumula- tive and complementary mutations, the disease-resistant F6 generation were analyzed for consecutive 2-years. New SCN3 resistant germplasm resources were identified and new varieties were released, which improved the genetic make-up and broadened the kinship resistant to SCN, and laid the foundation for future SCN3 re- sistant breeding.
