40多年来,我省育成水稻品种的系谱组成中几个骨干亲本的血缘主要来自早籼广、陆矮4号、矮脚南特,中籼IR26、IR29、密阳23,晚粳农垦58等,占全部育成品种(不包括地方品种)的70%。未来的育种策略,除以现有育成品种为基础外,还必须进一步开发和引进国内外优质稻种资源,拓宽遗传背景,不断丰富我省水稻育成品种的遗传基础,提高品种的增产潜力和适应能力。
For more than 40 years, the bloodlines of several key parents in the pedigree of Yulong rice cultivars in our province mainly come from Zhaoxianguang, Luchai 4, Dwarf Nanant, Indica IR26, IR29, Mieyang 23, Late Japonica Nongken 58 , Accounting for 70% of all bred varieties (excluding local varieties). In addition to the existing bred varieties, future breeding strategies must further develop and introduce high-quality rice seed resources at home and abroad, broaden the genetic background, continuously enrich the genetic basis of rice breeding varieties in our province, and increase the yield potential and adaptation of varieties ability.
