摘要
该研究利用当地推广的优良品种皖豆 16号 (MS8118)经等离子处理后的突变高产株系为母本与豫豆 10号有性杂交 ,育成具有特异株型的夏大豆超高产种质MN4 13,有效地把等离子诱变技术应用在大豆育种上 ,在黄淮地区获得 315 .0 8kg/ 667m2 的籽粒产量。其植株形态表现为 :根系特别发达 ,高抗倒伏 ;株形收敛紧凑 ;植株繁茂 ,主茎节数适中 ,有效节数多。其高产栽培的技术核心是 :生育前期抓构健壮苗匀植群体 ;中后期抓生长调节和营养运转 。
Summer soybean germplasm MN413 with specific characters was breed from hybrid generation in which mutant from soybean variety Wandou 16,which was treated by N + implantation, sexually crossed with Yudou 10. In the research,the technique of N + implantation was applied to soybean breeding. As a result the 315.08kg/667m 2 grain weight of MN413 was harvested in Huanghuai area. The morphological characters of MN413 were: stronger root system, high lodging-resistant, compact plant,luxuriant growth and normal...
