油菜籽含油量的遗传性较稳定,与产量相比,受环境影响较小,又由于受较少的基因控制,一般说来,含油量育种比产量育种见效更快。苏联的阿罗普钦柯(1959)曾认为,油菜籽的含油量提高到60％是完全可能的。 选育高含油量品种的途径,一般有杂交育种,连续单株正向选择和辐射诱变等。近年来,国内外许多油菜育种工作者,除了采用这些传统的育种方法外,还致力于将黄色种皮作为指示性状进行高含油量育种,并已取得成效。
Oilseed rapeseed genetically stable, compared with the yield, less affected by the environment, but also due to less gene control, in general, oilseed breeding effect than the yield breeding faster. Alopqenko (1959) of the Soviet Union once thought that it was entirely possible to increase the oil content of rapeseed to 60%. Breeding breeding methods of high oil content, generally hybrid breeding, continuous positive selection of plants and radiation mutagenesis. In recent years, many domestic and foreign rapeseed breeders, besides using these traditional breeding methods, are also committed to breeding yellow seed coats as indicative oil-rich seeds and have achieved success.
