    摘要:

    依据地理远缘、遗传距离远杂交优势强及遗传学基因互补的原理,选用含有日本血缘、农艺性状优良、丰产性好的优良品系做母本,选用含有野生大豆血缘、综合性状较好、蛋白质含量高的优异材料做父本,进行有性杂交。自早期世代开始进行大豆灰斑病的接种选择,高世代进行品质跟踪分析及大豆疫霉病接种鉴定,通过定向培育,选育出遗传基础丰富,聚合了国内外多个高蛋白、高产、抗病品种(系)的优良基因,蛋白质含量45%以上,抗大豆灰斑病兼抗疫霉病的优质大豆新种质。

    Abstract:

    According to the principle that geographical and genetical distant materials have high heterosis because of genes complement, we crossed high yield and good agronomic characters line origining from Japanese soybean blood as female parent and a promising line having high protein content and derived from wild soybean as male parent. The soybean frogeye leaf spot was inoculated in early generations, and in advanced generations the quality had been analyzed and the soybean phytothora rot was inoculated. By directed selective breeding the new elite soybean germplasm that have multiple high protein, diseases resistance and high yield genes was derived, it had abundant genetic basis, its protein content was above 45 %, and it was resistant to frogeye leaf spot and phytothora rot.
