| 摘 要： | 对黑龙江省1995～2006年间每年种植面积较大的各生育期玉米品种(累积面积占总面积90%以上)种质基础分析表明,黑龙江省玉米育种的种质资源数量较多,来源复杂,但是亲缘关系相对狭窄,遗传基础贫乏。早、晚熟期品种的育种材料表现更为突出;生产上应用品种的种质资源主要集中于Lancaster群,明显存在遗传脆弱性。

| Abstract: | The analysis on the accumulation of annual planting area of main varieties of different growing period which occupied over 90 percent of maize planting area from 1995 to 2006 indicated that the kinds is more and the resource is complicated but the blood relationship is relatively narrow and the genetic foundation is poor in the maize of breeding germplasm in Heilongjiang province . As to early-maturing cultivar and late-maturing cultivar the situation is more serious. The germplasm resource really applied in production concentrates on Lancaster group, and the genetic vulnerability is obvious. |
