摘要:

旨在对四川盆地主栽油菜品种抗菌核病性进行监测评价,为品种合理应用提供参考依据。于2018、2019连续两年在田间病圃内,对31个油菜市场品种采用人工菌丝块组织接种法接种核盘菌,调查油菜茎秆、分枝角果等组织菌核病发病程度,评价各品种菌核病抗(耐)病性。结果表明:有21个品种抗性稳定,即两年抗病性表现一致。其中‘德虹油1号’高抗(耐)菌核病,‘德名油100’和‘科乐油998’中抗(耐)菌核病;‘科源油2号’、‘宜油17’等10个品种低抗(耐)菌核病。‘油研11’、‘德油5号’等8个品种低感菌核病。‘德油9号’、‘宜油19’等10品种抗(耐)性菌核病性不稳定或丧失。综上,‘德虹油1号’、‘德名油100’和‘科乐油998’3个品种可作为抗病育种亲本或利用品种进行病害防控推广应用。

Abstract:

The aims are to monitor and evaluate the resistance of rapeseed varieties to Sclerotinia stem rot in Sichuan Basin, and provide reference for rational application of rapeseed varieties. In 2018 and 2019, 31 rapeseed varieties were inoculated with Sclerotinia sclerotiorum by artificial mycelium inoculation method in field, the incidence of stem and branch pod of rape was investigated, and the resistance of each variety to Sclerotinia stem rot was evaluated. The results showed that, 21 varieties had stable resistance, in other words, they showed the same resistance in the two years. Among them, ‘Dehongyou 1’ was highly resistant to Sclerotinia stem rot, ‘Demingyou 100’ and ‘Keleyou 998’ were moderately resistant to Sclerotinia stem rot, and 10 varieties such as ‘Keyuanyou 2’ and ‘Yiyou 17’ were low resistant to Sclerotinia stem rot. Eight varieties such as ‘Youyan 11’ and ‘Deyou No. 5’ were low susceptible to Sclerotinia stem rot. The resistance to Sclerotinia stem rot of 10 varieties such as ‘Deyou 9’ and ‘Yiyou 19’ was unstable or lost. In conclusion, ‘Dehongyou 1’, ‘Demingyou 100’ and ‘Keleyou 998’ can be used as parents for disease resistance breeding or for disease prevention and control.
