合丰号大豆品种系谱分析

ANALYSIS OF FAMILY TREE OF HEFENG SERIES OF SOYBEAN VARIETIES

合丰号大豆 32个品种 84 .4 %来源于满仓金、荆山朴、丰收 6号×克山四粒黄、丰收 1号×蓑衣领四个族系。其基因库源于 33个祖先亲本。细胞核祖先亲本有 33个 ,细胞质祖先亲本有 8个。核遗传贡献率较大的祖先亲本为金元 (18.7% )、四粒黄 (18.3% )、白眉 (6 .9% )、十胜长叶 (5 .9% )、小粒豆九号 (5 .6 % )等。细胞质遗传贡献率最大的是四粒黄 (46 .7% ) ,其次是小粒豆九号(16 .7% )、白眉 (13.3% )。合丰号大豆直接利用亲本 36个。利用国内优良亲本克 4 430 - 2 0、合交80 0 9- 16 12等成功地育成了合丰 2 5号、合丰 35号等高产稳产大豆品种 ;利用国外抗病品种Ohio、Rampage、Wilkin直接作亲本育成高抗灰斑病品种 4个。合丰号大豆品种有 16个具有国外血缘 ,占品种总数的 5 0 %。随着年代的推移 ,合丰号大豆的细胞核、细胞质祖先亲本发生了变化。不同年代有其不同的主要贡献者 ,合丰号大豆遗传多样性是其成功的关键。

Eight-four point four percent of thirty-two Hefeng soybean varieties are from four soybean families Mancangjin, Jingshanpu, Fengshou 6 × Keshansilihuang and Fengshou 1 × Suoyiling. Gene banks consist of thirty-three final ancestors, thirty-three ancestors and eight cytoplasmic final ancestors. The final ancestors with greater contribution rate of heredity are Jinyuan (18.7%), Silihuang (18.3%) , Baimei(6.9%), Shishengchangye (5.9%), Xiaoliduo 9 (5.6%) etc. Cytoplasmic final ancestor with greathest contribution rate of heredity is Silihuang (46.7%), in the next place are Xiaoliduo 9 (16.7%) and Baimei (13.3%). Thirty-six parents are used directly in Hefeng soybean varieties. We bred high yield and stable yield soybean varieties Hefeng 25 and Hefeng 35 using domestic good parents Ke4430-20 and Hejiao 8809-1612. We bred four soybean varieties high resistant to Cercospora Sojina using foreign disease-resistant soybean Ohio and Reampage and Wilkin. Sixteen Hefeng soybean varieties contain foreign blood relationship , fifty percent in all Hefeng soybean varieties. The final ancestors of Hefeng soybean varieties changed with time. There are different imajor dedicators in different years. The genetic diversities of Hefeng soybean is the key to success
