摘 要: | [目的]研究黄淮海区玉米青枯病的田间自然筛选及接种鉴定。[方法]采用试验室接种鉴定及大田自然鉴定的方法,研究25份玉米自交系和61份群体材料对玉米青枯病的抗病表现。[结果]筛选出9份自交系及26份群体材料的抗病等级都在R(抗病)以上。多数种质资源的抗病性集中在3级和5级,为R(抗病)和MR(中抗)材料;未发现有9级(高感)材料。[结论]该研究为玉米青枯病在黄淮海区的防治提供技术参考。

Abstract: | [Objective] To research the field natural selection and inoculation identification of corn bacterial wilt in Huanghuaihai Region.[Method] Laboratory inoculation identification and field natural identification methods were adopted to research the performance of 25 corn inbred lines and 61 populations to corn bacterial wilt.[Result] A total of 9 corn inbred lines and 26 populations were screened with the resistance level above R.Disease resistance level of most germplasm resources were concentrated at levels 3 and 5,which were R (resistance) and MR (middle resistance).There were no germplasm resources above level 9.[Conclusion] This research provides technical references for the control of corn bacterial wilt in Huanghuaihai Region. |
