材油两用树种东京野茉莉家系差异及优良家系选择

摘要

14 families of 6-year-old Styrax tonkinensis were used for the variance and genetic parameter analysis of growth and seed traits, then the multi-trait comprehensive evaluation method was taken to select the excellent fami-lies.The results showed there was significant or great significant difference among families in the growth and eco-nomic traits;the variation coefficient of each trait among families was 0.03~0.36 , and the family repeatability was 0.25~0.99 , mostly affected by family genetic factors;Family No.44 and No.31 were selected to be the ex-cellent families by multi-trait comprehensive evaluation method.%利用6年生东京野茉莉14个家系试验林的测定材料，开展生长和结实性状差异及遗传参数分析，并采用多性状综合评价方法筛选出部分优良家系。结果表明，各家系间生长性状和经济性状存在显著或极显著差异；家系间各性状的变异系数为0畅03～0畅36，而家系重复力为0畅25～0畅99，家系受遗传控制影响较大；多性状综合评价方法筛选出44号家系和31号家系为优良家系。
