色素万寿菊杂交品种与常规品种的主要农艺性状研究

摘要

The differences significant analysis, clustering analysis and comprehensive evaluation had been done on 8 agronomic traits of 18 kinds of pigment margold. Differences significant analysis showed that there exists very significant difference in every agronomic traits; Clustering analysis got four groups, the better comprehensive agronomic traits is groupⅠ(hybrid 15) and groupⅡ(hybrid 13). Comprehensive evaluation showed that hybrid 15 is the best; hybrid 13 is second to the former. and strain 3 is the best, strain 2 is the second among conventional materials,.%对18份色素万寿菊材料的8个主要农艺性状进行了差异显著性分析、聚类分析及综合评价.差异显著性分析说明,各主要农艺性状均存在极显著差异.聚类分析结果表明:18份色素万寿菊供试材料可分成4个类群,综合农艺性状较好的是类群Ⅰ(杂交15)与类群Ⅱ(杂交13).综合评价结果表明:杂交品种中,杂交15表现最好,杂交13次之;常规材料中,品系3最好,品系2次之.
