摘要
“八五”期末从杉木中心产区福建省引进优良无性系。３年测定表明，供试无性系树高、新梢、胸径、冠幅、分枝盘数及保存率存在极显著或显著的遗传性变异。生长显著超过优良种源（广西融水杉木）对照的有１个无性系５号。同时发现经１代改良的最优家系子代（２９号）在供试群体中表现最佳，树高比对照增加５３．３％。经综合评定初选出５号，１３号，１６号，２４号，２６号等５个无性系，树高比优良种源对照增加１２．６％～４０．４％。这些无性系和改良代优良家系，可作为优质高产、稳产杉木选育材料，在科研和生产中应用。
The Chinese fir superior clones were introduced from Fujian Province,the centre of growing district in nation’s Eighth Five year.The result of measurement on three years old trees shows that there are very significant or significant genetic variation in hight,new growth,diameter breast height,crown diameter,branchy courses and preserve rate.The growthes of clone No.5(040) are more check(Guangxi Rongshui Chinese fir).The filial generation (No.29)of elite family is best,it’s hight increment is by 53 3% more than check.The clones No.5(40),No,13(25),No.16(128),No.24(197),No.26(205)’s height increment are by 12 6%～40 4% more than check.
