摘要
以树高性状> CK 30%对永吉县林木种子站红松第一代种子园4年生红松单亲本子代进行评定,结果表明:61#、27#、68#、75#、29#、28#、64#、71#、31#、38#、73#、78#、81#、82#、37#、34#、74#、22#、44#、16#、17#、12#、63#、25#、10#、66#、36#等27个家系为红松优良家系,占参试家系的56. 25%,红松优良家系树高平均遗传增益为10. 39%。
The tree-high trait>CK 30%was used to evaluate the 4-year-old single parent in the first generation seed orchard of Pinus koraiensis in the seedling station of Yongji County.The results showed that 27 families of 61#,27#,68#,75#,29#,28#,64#,71#,31#,38#,73#,78#,81#,82#,37#,34#,74#,22#,44#,16#,17#,12#,63#,25#,10#,66#,36#were excellent families of Pinus koraiensis,accounting for 56.25%of the family members,and the average genetic gain of Pinus koraiensis trees was 10.39%.
