以混合家系为对照,对云南松12个种源78个家系的苗高和地径生长性状进行了测定与分析。结果表明:不同种源、家系与混合家系间的苗高和地径生长差异显著,其中表现最好的是云南石屏种源,其次为云南宜良、弥渡、禄丰和四川德昌种源,表现最差的是四川盐边种源;参试家系苗高生长量表现最好的是石屏龙朋45号家系,地径生长量表现最好的是石屏龙朋52号家系;苗期综合表现较好的家系有17个,分别是3、4、22、23、41、45、47、51、52、54、55、65、67、73、74、78、80号家系和混合家系;采用不同种源苗木地径和苗高进行逐步聚类分析,12个种源可分为5类,根据各种源苗期地径、苗高的生长状况,初步筛选出云南石屏种源高径生长均最好,云南腾冲、弥渡、禄丰、宜良和四川德昌种源生长次之。
Based on the mixed pedigree, the seedling height and diameter growth traits of 78 families from 12 provenances of Pinus yunnanene were determined and analyzed. The results showed that there was significant difference in seedling height and diameter growth between different provenances, pedigrees and mixed families. Among them, ShiPing provenance was the best in Yunnan Province, followed by Yunnan Yiliang, Midu, Lufeng and Sichuan Dechang provenances , The worst is the provenance of Sichuan Yanbian. The highest growth rate of seedling height in the test line is the pedigree of No.45 Shibei Longpeng. The families with good comprehensive performance in the period were 17, which were 3, 4, 22, 23, 41, 45, 47, 51, 52, 54, 55, 65, 67, 73, 74, Pedigree; using different provenances nursery ground diameter and seedling height for cluster analysis, 12 provenances can be divided into 5 categories, according to various sources of seedling stage diameter and seedling height of the initial screening of Yunnan Shibing species Source high diameter growth are the best, followed by Yunnan Tengchong, Midu, Lufeng, Yiliang and Sichuan Dechang provenances.
