对11份玉米常用骨干自交系及8份重点推广的玉米杂交组合的抗病性进行苗期人工接种鉴定。结果表明,试材之间抗性差异较大,抗性较好的试材有沈137、Mo17、799、沈试29、丹玉13和丹408等。杂交组合的抗病性与母本及父母本中亲值相关密切,相关系数r分别为093和094,而与父本相关系数r为017,母本的抗病性对杂交组合的抗病性决定程度较大。 Disease resistance of 11 common maize inbred lines and 8 key maize hybrid combinations were identified by artificial inoculation at seedling stage. The results showed that there was significant difference between the tested materials, and the resistant materials were Shen 137, Mo17, 799, Shen29, Dan Yu13 and Dan 408. The disease resistance of the crosses was closely related to the parents and parents’ progenies, the correlation coefficients r were 093 and 094, respectively, while the correlation coefficient r with the parents was 017, Decided to a larger extent.
