摘要
为了考察早熟品种在稻-稻-油三熟栽培地区的适应性及其特征特性,采取直播方式,对不同来源的10个早熟材料进行了早熟性、产量和抗性等的比较。结果表明:从早熟性来看,G-7和德油早1号成熟期最早,杂1062、早0902和早0904成熟期较早;从产量来看,早0902、早0904和G-7均比对照增产10%以上。通过对综合性状的考察,初步得出以下结论:早0902、早0904和G-7三个品种可以作为湖南省境内稻-稻-油三熟制栽培的早熟油菜品种。
Ten early-maturing varieties which origin from several units have been used for comparisons of early maturity,yield and resistance via using a triplicate randomized blocks design and direct seeding way.The results suggested that G-7 and Deyou 1 were the earliest maturing varieties,following by Za1062,Zao0902 and Zao0904.As the unit yield,Zao0902,Zao0904 and G-7 yielded 10% more than the check variety.So Zao0902,Zao0904 and G-7 would be used as commercial early-maturing varieties planted for the rice-rice-rapeseed cropping system in Hunan province.
