普通菜豆资源抗菜豆象鉴定与评价OA
Identification and Evaluation of Resistance to Acanthoscelides obtectus in Common Bean Germplasm Resources
采用人工接虫法对 473个普通菜豆资源进行菜豆象抗性鉴定.结果表明,49.1%的资源表现出不同程度的抗性,其中高抗资源 15份,抗性资源 60份,中抗资源 157份.在高抗资源中,F1432、F0645、F0675、F0004351和F0004406未见菜豆象侵染,表现为免疫.研究发现,菜豆象具有一定的趋光性,不同粒色、籽粒大小和种皮光泽的资源间未发现有明显的抗性差异.抗菜豆象资源的筛选鉴定,有利于为后续抗性育种提供优异的抗性资源.
The resistance of 473 common bean resources to Acanthoscelides obtectus was identified by artificial inoculation method.The results showed that 49.1%of the resources showed varying degrees of resistance,mcluding 15 highly resistant resources,60 resistant resources and 157 moderately resistant resources.In the highly resistant resources,F1432,F0645,F0675,F0004351 and F0004406 did not show any infected symptoms,manifesting as immunity.Research found that A.obtectus has a certain phototaxis.No significant differences in resistance were found among resources with different grain color,grain size,and seed coat luster.The screening and identification of A.obtectus resistant resources is beneficial for providing excellent resistance resources for subsequent resistance breeding.
