摘要
为提高冀东稻区水稻抗稻瘟病育种水平,对157份粳稻资源通过田间诱发感病鉴定其稻瘟病抗性,并利用12个抗病基因标记进行基因型鉴定。结果表明,157份粳稻资源中表现为抗、中抗、中感、感及高感材料分别为2、70、64、9、12个,其中,材料ZY1和ZY2表现为抗。Piz和Pid3这两个抗病基因出现频率最高,而Pigm、Pia、Pita、Pik和Pi5在本地区对稻瘟病的抗性上起到主效作用,且聚合越多抗性基因,抗病性越高。结合种质资源农艺及产量性状,发现ZY2、ZY13、ZY15和ZY21适合作为抗稻瘟病育种的亲本。
In order to improve the breeding level of rice blast resistance in eastern Hebei Province,157 japonica rice resources were identified by field-induced susceptibility for rice blast resistance,and 12 disease resistance gene markers were used for genotype identification.The results showed that among the 157 japonica rice resources,there were 2,70,64,9 and 12 materials showing resistance,medium resistance,medium susceptibility,susceptibility,and high susceptibility,respectively.Among them,materials ZY1 and ZY2 showed disease resistance.The resistance genes Piz and Pid3 had the highest frequency,while Pigm,Pia,Pita,Pik and Pi5 played the main role in the resistance of rice blast in eastern Hebei Province,and the more genes aggregated,the higher the resistance.Combining the agronomic traits and yield traits of germplasm resources,it is found that ZY2,ZY13,ZY15 and ZY21 are suitable as parents for rice blast resistance breeding.
