| 摘 要： | 以湖南农业大学芒属能源植物资源圃8份种质资源材料的种子为研究对象，对种子长、宽、厚、长宽比和千粒质量5个种子表型性状进行了系统比较分析。采用方差分析、多重比较、相关分析和聚类分析等方法对这8份材料种子表型性状差异进行了探讨。结果表明:8份种质资源材料的种子在5个性状上都达到极显著水平差异，不同材料种子之间表型性状变异系数均值的大小顺序是种子厚＞长宽比＞宽＞长＞千粒质量；相关性分析表明种子长与种子宽、种子千粒质量有显著关系，种子宽与种子厚、千粒质量有极显著相关性，种子厚与千粒质量有极显著相关性，长宽比与种子宽、种子厚、千粒质量呈现负相关；系统聚类可以将这8个材料分为3类。

| Abstract: | With the seeds from 8 germplasms of energy crop Miscanthus which were cultivated in the nursery of Hunan Agricultural University as materials，their seed phenotypic traits，including seed length，width，thickness，ratio of length and width and 1000-seeds weight were investigated.The seed phenotypic differences between eight germplasms resources were studied by the methods of ANOVA analysis，multiple comparison，correlation analysis and hierarchical cluster analysis.The extremely significant differences were observed in the five traits between germplasms，the order of the mean variation coefficient of phenotypic traits for energy crop Miscanthus seed between different germplasms was:thickness＞ratio of lengthwidth＞width＞seed length＞1000-seed weight.Seed length had a significant positive correlation with seed width and 1000-seed weight.Seed width had an extremely significant positive correlation with seed thickness and 1000-seeds weight.Seed thickness had an extremely significant positive correlation with 1000-seed weight.Ratio of seed lengthwidth had a negative significant correlation with seed width，thickness and 1000-seed weight.The eight germplasm resources of energy crop Miscanthus were classified into three groups by using hierarchical clustering analysis. |
