| 摘 要： | 对班克松50个家系进行了选择试验,结果表明：不同家系间苗期、2~6 a生树高、地径差异达到显著或极显著水平.采用独立淘汰水平法,以树高性状〉ck 15%为标准,选择出24个优良家系,占供试家系的48%.优良种源林中选择出的优良家系占全部优良家系的70.83%;优良家系树高、地径遗传力分别为0.829 4和0.808 4,树高、地径遗传增益分别为27.69%和26.02%.在优良家系中选择出40个优良个体,树高、地径遗传增益分别为43.19%和39.12%.

| Abstract: | 50 families of Pinus banksiana are selected to test,the results show that the different families at seedling state,2～6 a tree height,ground diameter reach obvious difference.24 super families are selected on the basis of independent eliminative method,tree height ck 15%,it accounts for 48%.The superior family selected from superior provenance forest accounts for 70.83%;The genetic abilities of tree height and ground diameter of superior family are 0.8294 and 0.8084 respectively,the genetic gain of tree height and ground diameter are 27.69% and 26.02% respectively.40 excellent individuals are selected from superior family,the genetic gain for height and ground diameter at breast height are 43.19% and 39.12% respectively. |
