- 摘要:
- 随着黑龙江省种植结构的调整，黑龙江省第三、四积温带由以大豆为主转变为以玉米为主要作物的玉米种植新区。为了在黑龙江省第三积温带玉米种植新区选择抗玉米大斑病品种及科学布局，以黑龙江省依安县为第三积温带玉米种植新区的代表，对该地区的29个玉米品种抗大斑病的特性进行评价。结果表明：不同玉米品种之间抗病性差异较大，病情指数变化为3.70～45.93。抗病性大致可分为三大类，抗病性较好的品种（病指≤15）为德美亚3号、吉单441、德元101、哈丰1号、稷禾农18、吉农大516、龙单48、龙作2号、北种玉1号、富单1号、良早66、育丰325、龙育415、九单503、垦单10号、禾田1号、吉单27、育丰311、嫩单15、宏育415、良玉21、吉农大212和龙垦9号；抗病性中等的品种（30≥病指≤15）为克单9号、东农254和吉单519；抗病性最差的品种（病指＞30）为丰单4号、华农292和龙单20。
- Abstract:
- With the adjustment of planting structure,the third and fourth accumulative temperature belts become new area of maize instead of soybean in Heilongjiang province.For selection of maize disease-resistant varieties and rational distribution against northern leaf blight in planting new area of the third accumulative temperature belt in Heilongjiang province，the 29 maize varieties were used to analyze resistance against northern leaf blight.The results showed that disease index of different maize varieties existed significant different and changed from 3.70 to 45.93.According to result of variance analysis and multiple comparison,three resistant levels were divided as high resistant cultivars(disease index≤15),moderate resistant cultivars(30≥disease index>15)and sensitive varieties(disease index>30),high resistant cultivars included Demeiya 3,Jidan 441,Deyuan 101,Hafeng 1,Jihenong 18,Jinongda 516,Longdan 48,Longzuo 2,Beizhongyu 1,Fudan 1,Liangzao 66,Yufeng 325,Longyu 415,Jiudan 503,Kendan 10,Hetian 1,Jidan 27,Yufeng 311,Nendan 15,Hongyu 415,Liangyu 21,Jinongda 212 and Longken 9;Moderate resistant cultivars(30≥disease index>15)included Kedan 9,Dongnong 254 and Jidan 519;Sensitive varieties(disease index>30)included Fengdan 4,Huanong 292 and Longdan 20.
