【摘要】 鉴定了 1 4份玉米杂交种及 1 5 0份玉米自交系成株期对弯孢菌叶斑病的抗性。结果表明 ,供试材料均可受到玉米弯孢菌叶斑病菌不同程度的为害 ,抗性较好的试材有丹玉 1 3号、丹玉 1 6号、农大 1 0 8号、豫玉 2 2号、豫玉 2 4号、农乐 1号、白 36 0、郑白 72、Mo1 7、8970 0 9等。抗性较差的试材有掖单 1 3号、掖单 1 9号、掖单 2 4号、黄早四、4 78、5 2 1 0 6、E2 8等。母本的抗病性对杂交组合的抗病性影响较大 ,父本的抗病性对杂交组合的抗病性影响较小更多还原

【Abstract】 The disease resistance of 14 kinds of hybrid strains and 150 kinds of self-mating strains of maize in stem period to Curvularia lunata was identified .The results showed that the strains tested all did damage to a certain extent. The strains which showed strong disease resistance were those of Danyu13, Danyu16, Nongda108, Yuyu22, Yuyu24, Nongle1, Bai360, Zhengbai72, Mo17, 897009 etc. The strains which showed less disease resistance were those of Yiedan13, Yiedan24, Huangzao4, 478, 52106, E28 etc. The maternal disease resistance had big effect on the disease resistance of hybrid combination.更多还原
