摘要： 本文利用典型相关分析的方法,研究了核桃的四个结实特性(总果枝量、果枝比、母枝抽生果枝数和果枝结果数)与六个果实性状(青皮厚、青果重、坚果重、壳厚、出仁率和含油量)之间的关系.结果表明,核桃结实特性与果实性状之间不存在显著的相关,而在不同结实特性之间及不同果实性状之间则存在较好的相关性.该研究有助于利用相关选择提高选种效率.

Abstract: The relationship between fruiting properties (total fruitful shoots,fruitful shoot ratio, fruitful shoots/mother branch, and nuts/fruitful shoot) and fruit characters (green peel thick, green fruit weight, nut weight, shell thick, edible kernel rctio and oil content) was studied with canonical correlation analysis. The results showed that there was no significant correlation between the two groups, but the correlation between items in eachgroup was significant. The study can help raise walnut seed selecting efficiency with correlated selection.
