早熟高产优质杂交油菜新品种“赣油杂1009”的选育
|
摘要
[目的]选育和推广应用早熟油菜,避免或减轻江西3熟期油菜产区油菜生育后期的高温逼熟或干热风等灾害的危害,为三熟制早稻等后茬作物及早腾地,保证后茬作物的高产、稳产并确保我国粮油安全供给。[方法]恢复系和不育系主要通过系统选育,综合性状和适应性主要通过品比试验和区域试验进行鉴定和筛选。[结果]"赣油杂1009"在江西省早熟组各点试验中均表现出较好的早熟性,开花较早,终花早,具有较好的高产、稳产性能和增产潜力,综合农艺性状优异。[结论]早熟性育种重点是进行花期选择,油菜初花和终花期的迟早可在一定程度上反映油菜成熟期的早晚,可以作为生育期选择的依据。
[Objective] Precocious rape was bred and applied to avoid or reduce damages such as high temperature cooked or dry-hot wind disasters in 3 ripe stage rape producing area in Jiangxi,and ensure the high and stable yield of after-reap crop and ensure the security of grain and oil supply in China.[Method]Restorer lines and the sterile lines were bred by system breeding,and comprehensive properties and adaptability were evaluated and selected mainly through varieties comparative test and regional tests.[Result] Ganyouza No.1009 was tested as earlier flowering and end flowering at various points in Jiangxi Province,precocious group showed better precocity,good yield,yield increasing potential and excellent comprehensive agronomic traits.[Conclusion] The key of early maturity breeding is chosing flowering stage.To a certain extent,the sooner or later of rape mature can be reflected by coming and eventually blooming sooner or later,as the basis of growth period choice.
