摘要
[目的]研究东油1号的产量形成及高产栽培技术。[方法]双低甘蓝型油菜东油1号以(镇8901×湘油10号)F3为母本,以(镇8705×苏油1号)F2为父本杂交,经5代选择育成。通过区域、生产试验,分析东油1号的特征特性、品质和产量,提出了高产栽培措施。[结果]东油1号属半冬性甘蓝型常规油菜中熟品种,优质双低,总角果数多,分枝数偏多,枝上角果分布密集,千粒重3.77g,增产潜力大,抗病性强,抗倒性极强,适宜机械化收割,品质优,适宜在江苏省油菜区推广种植,中间试验平均产量为2494.95kg/hm2,比对照苏油1号增产4.66%。[结论]东油1号蕾大花大,角果挺,单株有效角果数多。适期播种,培育壮苗,合理密植,及时进行肥水管理和病虫草害防治,才能夺取高产。
Objective The purpose was to study the yield forming and high-yield cultivation technique of Dongyou 1.Method The double low rapeseed variety Dongyou 1 was bred by selecting for 5 generations in the cross with（Zhen 8901×Xiangyou10）F3 as female parent and（Zhen8705×Suyou 1）F2 as male parent.The characteristics,quality and yield of Dongyou 1 were analyzed through regional and production tests,and the high-yield cultivation measures were put forward for Dongyou 1.Result Dongyou 1 belonged to semi-winter conventional rape variety（B.napus）with middle mature,which was double low with good quality,numerous total pods distributed closely on branch,more branches and 1 000-seed weight of 3.77 g,big increase potential,strong disease-resistance and extremely strong falling-resistance.It had good quality and was suitable for mechanized harvesting and popularizing and planting in the rape area of Jiangsu province,with average yield of intermediate test being 2 494.95 kg/hm^2,increasing 4.66 % than CK Suyou 1.Conclusion Dongyou 1 has big buds and flowers,full pods and numerous available pods per plant.Its high-yield can be obtained by sowing at right time,cultivating strong seedlings,rational close planting and conducting fertilizer and water management and disease,pest and weed control in time.
