摘　　要：为了筛选牛角瓜优良种质,以4个不同种源牛角瓜(Calotropis gigantea)为材料,分析其果实的经济性状及早期生长表现。结果表明,不同种源牛角瓜果实的经济性状指标有显著或极显著差异,种源间存在着丰富的遗传变异。引种南宁后,种源间、单株间生长差异较大,通过综合分析与评价,海南儋州种源的表现最优。In order to screen out excellent germplasms,four different provenances of Calotropis gigantea were used to analyze economic characters and early growth.Results showed that there were significant or extremely significant differences among economic characters,and there were abundant genetic variations among different provenances.After being introduced to Nanning,growth differences among provenances and individual plants were large.Through comprehensive analysis and evaluation,performance of Danzhou provenance was the best.
