摘　　要：以36年生云杉嫁接无性系试验林为试验对象,对材积、基本密度、弹性模量3个目标性状以单性状育种值排列法、独立挑选法、综合评分法、多性状等权重指数法、多性状约束指数法等5种方法进行选择和比较。结果表明:在无法获取遗传参数时,仅以表型性状均值进行选择,独立挑选法为最佳选择方法;在可以获取遗传参数时,多性状约束指数法为最佳选择方法。In this study,36-year-old spruce grafted clone test forest was used as the test object,and three target traits of volume,basic density and elastic modulus were ranked by methods including single-trait breeding value,independent selection method,comprehensive scoring method,multi-trait weighting index,and multi-trait constrained index method.Five methods were selected and compared.The results show that independent selected method is the best selection method when the genetic parameters cannot be obtained excepted for the mean value of phenotypic traits;multi-trait constraint index method is the best selected method when the genetic parameters can be obtained.
