| 摘 要： | 在资源调查的基础上,针对“石棉巨型”核桃及“川早1号”、“川早2号”、“川早3号”、“双早”、“蜀玲”核桃的腹径、缝径、果高、壳厚、单果重、仁重、出仁率、粗脂肪含量、粗蛋白含量9个主要经济性状指标,采用相关性分析、主成分分析及聚类分析等方法,对绵竹县核桃资源进行综合评判.结果表明:“石棉巨型”核桃坚果大小明显高于其它5个杂交早实核桃良种,表现出巨型果的优势,在出仁率、粗脂肪含量等方面表现良好；壳厚、单果重、仁重两两呈极显著正相关.主成分分析结果表明,6个核桃样本主成分综合得分依次为:“石棉巨型”＞“川早3号”＞“川早2号”＞“川早1号”＞“双早”＞“蜀玲”.聚类分析得出,“石棉巨型”核桃单独聚为一类,其它5个品种聚为另一类,表明巨型核桃与其它5个品种表现出较远的亲缘关系.
