| 摘 要： | 为进一步挖掘糯玉米育种基因资源,对40份西北糯玉米自交系的农艺性状进行了分析。结果表明,供试材料的农艺性状存在丰富的表型遗传变异。相关分析表明,简单相关和偏相关分析中分别有25和10对农艺性状达到极显著相关,其中散粉期与抽雄期,吐丝期与散粉期,株高与穗位,秃尖与穗长,穗行数与穗粗,单穗重与穗长,单穗重与穗粗间简单相关和...

| Abstract: | The 14 agronomic traits of 40 waxy corn inbred lines collected from northwest China were investigated by analysis of variance,correlation,principle component analysis and cluster.The results showed that higher variation in the 14 agronomic traits was observed among these tested materials.The result based on correlation analysis indicated that there were 25 and 10 pairs of characters with significant correlations in simple and partial correlation analysis,respectively.According to principle component analysi... |
