【摘要】 为筛选适合湖南双季稻区冬季种植的双低早熟油菜品种,2010～2011年在长沙引进12个油菜品种进行比较试验。结果表明:青杂3号和青杂7号生育期最短,为195 d,比对照(杂1613)早4 d,但产量较低,而G-11产量最高,达3 122.55 kg/hm2,比对照增产18.76%,生育期比对照短2 d。通过对12个参试品种的综合考察,2010-14、早0902、G-7和G-11产量优势明显,早熟性强,适宜在湖南地区种植。更多还原

【Abstract】 Twelve rapeseed varieties introduced from several institutes were used for comparison test in order to understand the related traits of early-maturing Brassica napus L.and screen early-maturing double-low rapeseed varieties suitable for double cropping rice areas of Hunan.The results showed that growth duration of Qingza 3 and Qingza 7 was shortest,195 days,which was earlier 4 days than CK,while their yield was lower because of many reasons.Yield of G-11 was highest,3 122.55kg/hm2,which was increased by 18.76% than CK,and it’s growth duration was shorter 2 days than CK.Comprehensive evaluation on all tested varieties showed that 2010-14,Zao0902,G-7 and G-11 were suitable for Hunan province because of high yielding and early-maturing.更多还原
