目的]为宜油系列油菜品种推广利用提供理论依据。方法]对宜油系列油菜品种进行田间施放菌核、自然诱发鉴定试验。结果]结果表明,宜油系列油菜品种间抗菌核病能力有明显的差异。所鉴定的6个宜油品种中,宜油13号表现为高抗菌核病,宜油15中抗菌核病,宜油11号、宜油12号低抗菌核病,宜油9号、宜油10号低感菌核病。宜油13号和宜油15在抗菌核病和产量方面都表现出明显的优势。结论]宜油13号、宜油15有较强的抗菌核病能力和高产性能,具有较大的推广潜力,适宜四川及类似生态区域推广种植。

Resistance Identification and Evaluation of Yiyou Rape Variety Series

Objective] The aim of the research was to provide theoretical basis for the utilization and extension of Yiyou rape variety series.Method] Field experiment of applying sclerotium and natural induction identification was conducted on Yiyou rape variety series.Result] The resistances to sclerotium disease among Yiyou rape variety series had obvious difference.Among the 6 Yiyou varieties that were identified,Yiyou 13 showed high resistance to sclerotium disease,Yiyou 15 showed middle resistance to sclerotium disease,Yiyou 11 and Yiyou 12 had low resistance to sclerotium disease,and Yiyou 9 and Yiyou 10 were lower sensible to sclerotium disease.Yiyou 13 and Yiyou 15 both showed obvious advantages on the resistance and yield.Conclusion] Yiyou 13 and Yiyou 15 had stronger resistance to sclerotium disease,high-yield property and greater extension potentials,which were suitable for extending and planting in Sichuan province and similar ecological regions.
