辐射诱变培育高油大豆新品种及其应用

本文报导了高油品种培育和应用结果,并对高油品种选择的关键技术进行探讨。在杂交育种基础上,本研究通过遗传改良和辐射诱变处理,经过连续定向选择,利用品质分析、抗病鉴定等方法培育出合丰46号(合辐931544)、合丰47号(合辐931542)、合丰48号(合辐931556)和合辐931484等4个高油品种(系),油分含量21.28%～23.18%,单产2208～2578.5kghm2,产量较对照品种增加10.1%～13.1%,中抗一种或两种主要病害。

BREEDING AND APPLICATION OF HIGH-OIL SOYBEAN VARIETIES THROUGH RADIATION

This paper reported the results of breeding and utilizing of high-oil soybean varieties, and at the same time, discussed the key technique of selecting high-oil soybean variety. This research based on crossbreeding, through genetic improvement and radiation treatment, continuous directive selection, combined with quality analysis and disease-resistant identification, and we had created four high-oil soybean varieties(lines), they were Hefeng46 (Hefu93154-4), Hefeng47 (Hefu 93154-2), Hefeng48 (Hefu 93155-6), Hefu 93148-4. Their oil content ranges from 21.28% to 23.18%, and the yield is 2208～2578.5kg/hm~2, compared with the check, the yield is 10.1%～13.1% higher. All those varieties resisted one or two main soybean diseases.
