摘要: 为了明确主栽的大白菜以及大白菜育种材料与根肿菌生理小种之间的抗性关系,以现有4,7,10和11号生理小种为菌源,用注射法进行接种,对25份供试大白菜材料进行抗病性鉴定,同时利用分子标记检测供试材料中所含的根肿病抗性位点。结果表明:供试大白菜中,山地王2号等8份试材对4个生理小种都表现抗病,德高CR117等7份试材对4个生理小种都表现感病,C1等4份试材对2个生理小种感病,华抗301等6份试材只对4号生理小种感病;所有试材均含有Crr1抗病位点,德高CR117等11份试材含有Crr2抗病位点,仅在京春CR3中检测到Crr3抗病位点,除德高CR铁甲1号和大地CR118外,其他试材中均检测到了CRk抗病位点,有21,16份试材中分别检测到抗病位点CRaCRb,而CRc抗病位点仅在星光和CR75中存在。总之,不同大白菜材料对同一生理小种抗性反应不同,同一个材料对不同生理小种的抗性反应不同;所有生理小种中4号生理小种最强,其次为7号生理小种;大白菜材料抗病位点多一定抗病性强;Crr1抗病位点对材料抗性影响不大。

Abstract: To clarify the resistant relationship between physiological races and Chinese cabbage(Brassica rapa L.ssp. pekinensis) variety, physiological races 4, 7, 10 and 11 were inoculated by injecting. The disease resistance of the 25 Chinese cabbage and CR markers were detected. The results showed that 8 cultivars such as Shandiwang 2 were resistance to only 4 physiological races; 7 cultivars such as Degao CR117 were susceptible to only 4 physiological races; 4 cultivars (including C1) were susceptible to 2 physiological races, and 6 cultivars (including Huakang 301) were only susceptible to 4 physiological race. All materials contained Crr1, CRk was detected in samples except the Degao CR Tiejia 1 and the Dadi CR118, the disease resistance locus CRa and CRb were detected in 21 and 16 samples respectively, 11 cultivars (including Degao CR117) contained Crr2 resistance locus, Crr3 resistance locus was detected only in Jingchun CR3, CRc resistance locus was contained in Xingguan and CR75.In short,different Chinese cabbage materials have different resistance to the same physiological race,and the same material responds differently to different physiological races. The physiological race No.4 was the most serious, followed by the physiological race No.7. The results of molecular marker identification showed that the resistance sites of Chinese cabbage materials were not necessarily resistant to disease. The resistance of Crr1 had little effect on material resistance.
