摘　　要：[目的]分析益智野生居群间的遗传变异。[方法]统计海南野生益智居群的平均株高、单丛茎杆数、单丛果穗数、单穗重等影响产量的形态表型数据并计算其变异系数。[结果]居群间性状差异显著,变异系数差异较大,具有较丰富的遗传多样性。[结论]可以从海南野生益智群体中筛选出一些优良性状以供益智栽培种的品种改良。[Objective] The aim was to analyze the genetic variation of wild population of Alpinia oxyphylla. [Method] The average plant height, stems per cluster, fruits per cluster, single panicle weight of wild population of A. oxyphylla in Hainan and variation coefficients were calculated. [ Result] There were significant difference among traits and variation coefficients, with abundant genetic diversity. [ Conclusion] Several excellent characters can be screened out from wild population of A. oxyphylla in Hainan for variety improvement.
