摘要
为明确大连地区菜豆品种抗根腐病水平,通过病田试验和接种试验对18个菜豆品种进行根腐病抗性鉴定。结果表明,病田试验中所有品种均表现发病,且发病情况逐年加重;八月忙、连农玉丰架豆和连农美味2号发病最轻,2年平均病情指数分别为12.96、13.70、15.19。在接种试验中,抗病(R)品种有5个,其中3个的病情指数与中抗品种呈显著差异,包括连农玉丰架豆、连农美味2号和八月忙,病情指数分别为27.11、28.44和28.89;中抗(MR)品种11个,感病(S)品种2个,无免疫(I)和高抗(HR)品种。综合试验结果,鉴定出3个抗病菜豆品种,连农玉丰架豆、连农美味2号和八月忙不仅抗根腐病,而且农艺性状优良,既可以直接应用于生产,也可以作为抗根腐病种质资源进行改良和利用。
In order to clarify the resistance level of kidney bean varieties to root rot in Dalian area,the resistance identification to root rot and agronomic traits evaluation of 18 kidney bean varieties were carried out by disease field experiments and inoculation experiments.The results showed that in the field experiments,all varieties showed disease symptoms,and the incidence had been increasing year by year;August Busy,Liannong Yufengjiadou and Liannong Delicacy No.2 had the lightest incidence,the average disease indexes’for two years were 12.96,13.70,and 15.19.In the inoculation experiments,there were 5 resistant(R)varieties,of which 3 showed significant differences in disease index compared to medium resistant varieties,including Liannong Yufengjiadou,Liannong Delicacy No.2 and August Busy,the disease indexes’were 27.11,28.44 and 28.89;there were 11 moderately resistant(MR)varieties,2 susceptible(S)varieties,and no immune(I)and highly resistant(HR)varieties.Based on the experimental results,three resistant varieties were identified,Liannong Yufengjiadou,Liannong Delicacy No.2 and August Busy not only have resistance to root rot,but also have excellent agronomic traits.They can be directly applied in production and can also be used as germplasm resources for improvement and utilization of root rot resistance.
