摘要
为筛选出适宜于洞庭湖平原区稻田机械化免耕直播油菜新品种,以当地油菜主要品种华湘油12号为对照,采用稻田免耕直播的方法,分析比较了鼎油杂4号、创油杂5号、希望699、希望943、希望1679、希望2016、希望2019、盛湘油9号、常油杂3号等油菜品种的生育期、抗性、产量和产量构成因素。结果表明,希望1679、鼎油杂4号、希望2016、创油杂5号、盛湘油9号、希望2019和常油杂3号7个油菜品种的产量均高于对照,分别比对照增产17.7%、16.1%、14.5%、12.9%、11.3%、8.1%和3.2%;其中,希望1679、鼎油杂4号、希望2016和创油杂5号这4个品种的产量较高,抗菌核病和抗倒性较好,全生育期适中,适宜在洞庭湖平原区推广应用。
For screening new rape varieties suitable for the plain area of Dongting Lake, where mechanical no tillage and direct seeding is applied in paddy fields, the study took Hua Xiangyou No. 12 as the control, used the method of mechanical no tillage and direct seeding, compared the growth period, resistance, yield and yield constitute factors of ten rape varieties, which are Ding Youza No.4, Chuang Youza No.5, Hope 699, Hope 943, Hope 1679, Hope 2016, Hope 2019, Sheng Xiangyou No.9, Chang Youza No.3 and Hua Xiangyou No.12 （CK）. The results showed that the yields of Hope 1679, Ding Youza No.4, Hope 2016, Chuang Youza No.5, Sheng Xiangyou No.9, Hope 2019 and Chang Youza No.3 were higher than that of the control, which increased by 17.7%, 16.1%, 14,5 %, 12.9%, 11.3%, 8.1% and 3.2% respectively; among them, four rape varieties of Hope 1679, Ding Youza No.4, Hope 2016 and Chuang Youza No.5 were of high yieds and moderate whole growth period and their resistence to sclerotinia disease and lodging were relatively good, which would be suitable for the popularization and application in local areas.
