摘　　要：湘杂油5号是湖南省作物研究所育成的通过国家审定的"双低"两系杂交油菜品种。为加速其推广应用,开展了与该省主推品种湘杂油2号和湘油15号的性状比较研究。结果表明:(1)熟期早,比湘杂油2号早2d,比湘油15号早7d;(2)生长发育进程较快;(3)其产量优势主要表现在单株荚果数多和每荚粒数多。因此,在生产上要在适期范围内促早播,同时还要加强前期肥水管理,为后期生长发育和产量形成打下基础。Xiangzayou 5 bred by Hunan Crop Research Institute is a two-line hybrid rapeseed variety with 'double low' quality, released by the National Crop Cultivars Approval Committee.Xiangzayou 5 was compared in characters with the rapeseed cultivars Xiangyou 15, Xiangzayou 2.The results showed that Xiangzayou 5 had the following advantages: (1) earlier maturing;(2) quicker development;(3) more siliques per plant and more seeds per silique.Therefore,proper early sowing and good management of fertilization at early stages will lay a foundation for late development and yield formation of Xiangzayou 5.
