摘要
本试验通过构建花生网斑病苗圃,在吉林省公主岭和洮南两地开展早播与正常播种对花生网斑病影响的调查研究。对比不同品种(品系)在两个播期下的病情指数、相对抗病性,研究两地网斑病横向比较的发病规律。结果表明,主区处理A存在显著差异(F_(1,1)=638.4558,P=0.0001)。裂区处理B不存在显著差异(F_(1,1)=0.2747,P=0.6074)。裂区处理C存在显著差异(F_(1,21)=9.3508,P=0.0001)。22份花生品种(品系)在吉林省种植过程中,仅吉花17和农大652表现出明显中抗花生网斑病。
This study was conducted by constructing a nursery of peanut web blotch disease,conducted to investigate the effects of early sowing and normal sowing on the occurrence of peanut net leaf blotch in Gongzhuling and Taonan.Compare the disease index and relative resistance of different varieties(strains)under two sowing dates,and screen out the rules of horizontal comparison of net disease in the two places.The disease was a significant difference in the main area treatment A(F_(1,1)=638.4558,P=0.0001).There was no significant difference in the split area treatment B(F_(1,1)=0.2747,P=0.6074).There was a significant difference in the split area treatment C(F_(1,21)=9.3508,P=0.0001).Only Jihua17 and Nongda652 of the 22 peanut cultivars showed moderate resistance during the planting process in Jilin Province.
