【摘要】 采用主成分遗传距离聚类分析法 ,对 2 2 9个 1 3年生的马尾松优树子代进行综合分析评价。从中筛选出 1 9个高产稳定型优良家系 ,适宜在福建省范围内推广 ,其材积平均遗传增益为 2 8 30 %。 1 3个高产优良家系适宜在闽西北推广 ,其材积平均遗传增益为 2 1 0 7%。1 7个高产优良家系适宜在闽东南推广 ,其材积平均遗传增益为 2 5 51 %。表 6参 1 3更多还原

【Abstract】 The cluster analysis of the genetic distance of principal components was adopted to comprehensively evaluate the main growth traits of 229 13 year old plus tree progenies of masson pine.Among which 19 high yield and stable yield excellent families were selected,their average stem volume genetic gains reached 28 30%,and they could be popularized in the whole Fujian Proveince.Other 13 high yield fine families were suitable for northwestern Fujian and their average stem volume genetic gains reached 21 07%,and high yield fine families were suitable for southeastern Fujian whose volume genetic gains reached 25 5%.更多还原
