| 摘 要： | 从三峡库区征集72份玉米地方品种分别同改良Reid和改良Lancaster血缘自交系进行测配,采用灰色关联度分析法对这些地方品种产量及其构成性状进行了综合评价.结果表明这些玉米地方品种中具潜在利用价值的有16份,其中与改良Reid测验系测交表现出强优势的地方品种有6份,与改良Lancaster测验系测交表现出强优势的品种亦有6份,与两个测验系测交均表现出较强杂种优势的地方品种有4份.

| Abstract: | 72 native maize resources were collected from the Three Gorge Areas in 1996,they are respectively crossed with each of two inbreds derived from the improved Reid and Lancaster germplasm next year.The grain yield and its component characters were evaluated by grey correlative degree analysis.The result showed that 16 of these resources could have potential value for us.Among 16 resources,6 showed better heterosis,when they crossed with the improved Reid germplasm,another 6 crossed with the improved Lancaster germplasm showed better heterosis,and the rest 4 resources showed much better heterosis which crossed with both of the two improved maize germplasm. |
