摘　　要：通过对豫南山地11个乌桕品种的长期观测,对11个品种的生长性状和经济指标进行了综合分析,不同品种间差异显著。依据各品种指标值与产籽量呈正相关,用单株产籽量分组聚类分析,筛评选出了大粒葡萄桕和铜锤桕2个最优品种以及葡萄桕、五爪桕和葡鸡桕3个次优品种。最优品种和次优品种表现出生长势强,结果枝占比高,果穗整齐度高,稳产、高产、品质好等优良性状。最优品种产籽量是一般品种产籽量的2.28~6.63倍、最差品种产籽量的9.46~22.46倍;次优品种产籽量是一般品种产籽量1.19~4.32倍、最差品种产籽量4.92~14.62倍。且筛选出的这些优良品种为豫南山地乌桕林营造提供了良种支撑。Sapiumsebiferum is a kind of multipurpose tree species with good economic performance. This paper comprehensively analyzed the growth traits and economic indicators of 11 kinds of Sapiumsebiferum through the long-term observation of those different varieties in the mountainous area of southern Henan Province.The results shows that there were significant differences between different varieties. According to the positive correlation between the index value of each variety and the seed yield, this study found out the Tongchui tallow tree and Putao tallow tree(Sapiumsebiferum) were the best kinds of varieties, and the Putao tallow, tree Wuzhua tallow tree and Puji tallow tree(Sapiumsebiferum) were the second best by cluster analysis of seed yield per plant. The best varieties and sub-optimal varieties had a lot of excellent traits such as strong potential of growth, high ratio of fruiting branches, neat ears of the fruit, stable and high yield and good quality. The seed yield of the best variety was 2.28-6.63 times that of the normal variety and 9.46-22.46 times that of the worst variety. The seed yield of the sub-optimal variety is 1.19-4.32 times that of the normal variety, and 9.46-22.46 times of the worst variety. All of those selected varieties provide a good support for the afforestation of Sapiumsebiferum in the mountainous area of southern Henan Province.
