| 摘 要： | 通过田间干旱直接鉴定,采用模糊函数法进行综合评价,选出2个强抗、6个抗、3个中抗的玉米抗旱高产杂交组合,进一步通过品比试验研究各杂交组合的丰产性。结果表明,这11个组合均具有较高的产量潜力,达到10500kg/hm2以上,平均11142.90kg/hm2。经方差分析显示各组合与我省区试对照种兴黄单89-2产量水平相当或增产,是可以在生产上应用的抗旱高产杂交组合。不同玉米抗旱高产杂交组合表现高产的原因在于光合面积大、叶绿素含量高和光合生产性能好。

| Abstract: | We got 2 strong,6 medium and 3 average high-yield hybrid maize materials with drought-resistance by method of subordinate function values and direct appraisal by dry field test.We analyzed their fertility by field test.The result showed that the 11 hybrid maize materials all had an yield beyond 10 500 kg/ha and showed high-yield potential compared with CK Xinghuangdan 89-2.They can be all extended as high-yield material with drought-resistance.We thought the reason for high yield was large leaf area,high chlorophyll content and strong photosynthesis. |
