牡试6号的遗传解析及增产潜势研究

为研究黑龙江大豆育成品种的遗传解析及增产潜势规律,以黑龙江省农业科学院牡丹江分院选育的大豆品种牡试6号为研究对象,进行品种的亲本血缘特点和遗传贡献率分析。结果表明:牡试6号是通过四粒黄细胞质遗传的,具体选育过程:四粒黄→黄宝珠→满仓金→克交5501-3→绥农3号→绥农4号→绥81-242→黑农40→黑农48→牡试6号。细胞核由祖先亲本ZYD355野生豆、十胜长叶、嫩78631-5、四粒黄、金元、五顶珠、白眉、克山四粒荚、平地黄、Amsoy、Anoka、小粒黄、永丰豆、通州小黄豆、熊岳小黄豆、佳木斯突荚子、柳叶齐和东农20共同提供,核遗传贡献率分别是:25.00%、18.74%、12.50%、6.58%、6.58%、6.25%、3.14%、3.14%、3.14%、3.13%、3.13%、1.95%、1.56%、1.56%、1.19%、0.98%、0.78%、0.39%。牡试6号高度聚合了东北大豆核心种质的优良基因,经过大豆杂交重组基因,具有高产高蛋白的遗传基础潜力,其遗传解析及增产潜势的研究能够为大豆育种工作提供理论支持。

Genetic Dissection and Yield Increase Potential of Released Soybean Cultivar Mushi 6

In order to investigate the genetic dissection and competence of yield increase of accessed-varieties in soybeans, Mushi 6 which was breed by Mudanjiang Branch of Heilongjiang Academy of Agricultural Sciences was used as candidate to analyze the characteristics of all parental blood ties and genetic contribution. The results showed: Mushi 6 was inherited by cytoplasmic genetic of Silihuang, its transfer process was Silihuang→Huangbaozhu→Mancangjin→Kejiao 5501-3→ Suinong 3→Suinong 4→Sui 81-242→Heinong 40→Heinong 48→Mushi 6. Nuclear genes were provided by all the ancestors, including ZYD355, Tokchi Nagaha, Nen 78631-5, Silihuang, Jinyuan, Wudingzhu, Baimei, Keshansilijia, Pingdinghuang, Amsoy, Anoka, Xiaolihuang, Yongfengdou, Tongzhouxiaohuangdou, Xiongyuexiaohuangdou, Jiamusitujiazi, Liuyeqi, and Dongnong 20. The nuclear genetic contribution rate was 25.00%, 18.74%, 12.50%, 6.58%, 6.58%, 6.25%, 3.14%, 3.14%, 3.14%, 3.13%, 3.13%, 1.95%, 1.56%, 1.56%, 1.19%, 0.98%, 0.78% and 0.39%, respectively. The genetic genes of high yield of northeast core germplasm were polymerized by Mushi 6. The soybean hybridization and recombinant genes revealed that Mushi 6 has the genetic basis potential of high yield and high protein concentration, this research can provide theoretical support for soybean breeding.
