摘　　要：2012年对在小兴安岭地区内4个产地选择289个优树采种育苗营造的25年生红松子代测定林的树高、胸径进行了调查。经测定评比,选择优良家系20个,每个家系中再选3个优良单株,共计60个优良单株,入选率3%~6%,选择强度1.98~2.27,材积遗传力0.2~0.5,材积遗传增益10%~15%,材积比对照平均高出52.5%。同时,在带岭林木育种基地红松初级无性系种子园选择经过测定的结实量高于平均值50%以上的20个高产无性系优良单株,采用新法高接,先定砧木后嫁接的方式建园,可提前5~10年成园。The provenances of this research are come from four Pinus koraiensis origin places at Xiao Xin＇an Mountain, which used to build a seed orchard at Suilin forest bureau, Heilongjiang province. The provenances including 289 plus trees and the average age of seed orchard is about 25 years. In 2012, we investigate tree height and diameter, accord testing results, we select 20 superior families, and 3 select trees from each superior family, altogether 60 excellent individuals. Selection rate is 3% ~6%,selection pressure is 1.98~2.27, volume genetic is 0.2~0.5, volume genetic gain is 10%~15%.The volume 52.5% higher than compare on average; in the same time, we choose 20 superior clone families which seed production are 50%higher than average from first^generation orchard in Dailing after investigating, using new method and set root stock before grafting, we can establish orchard 5~10years in advance. We mean the seed production.
