红松优树自由授粉子代测定的数据分析

The data analysis of Pinus koraiensis select tree open pollination progeny test

以吉林省三岔子林业局国家红松良种基地的红松29a生子代测定林为材料,对树高和胸径生长性状进行测定和数据分析,结果表明:在41个参试家系中,家系间树高和胸径生长均值在0.05水平上差异显著。树高均值超过对照的家系有31个,占家系总数75.6%,胸径均值超过对照的家系有29个,占70.7%;树高均值超过对照10%的家系有1个,占家系总数2.4%,超过对照5%的家系有8个,占19.6%;胸径均值超过对照10%的家系有4个,占9.8%;超过对照5%的家系有8个,占19.6%;42#和75#家系的树高与胸径生长均大于对照5%以上。以树高和胸径生长超过对照5%为入选标准,入选率为19.6%。树高和胸径生长最优家系分别为57#与75#,一般配合力分别为1.788与6.902。树高和胸径遗传力分别为0.393与0.363;遗传增益分别为2.9%与4.5%。

The test and data analysis were carried to height and diameter at breast height growth trait by choosing the 29 year Pinus koraiensis progeny test forest of Sanchazi forestry bureau of Jilin province as material. The result showed that height and diameter at breast height growth mean value was significant difference in 0.05 level in 41 families. There were 31 whose height mean value exceeded the control which took up 75.6%. Furthermore, there were 29 whose height mean value exceeded the control which took up 70.7%. There were 1 and 8 whose height mean value exceeded 10% and 5% of the control which took up 2.4% and 19.6%. There were 4 and 8 whose height mean value exceeded 10% and 5% of the control which took up 9.8% and 19.6%. The height and diameter at breast height growth of 42# and 75 # were 5% higher than the control. The selection rate was 19.6% according to the selection standard of the height and diameter at breast height growth exceeded 5 % of the control. The optimal family of height and diameter at breast height growth was 57 # and 75 #. The common combining ability was 1. 788 and 6. 902. The heritability of height and diameter at breast height growth was 0. 393 and 0.363. The genetic gain was 2.9% 与 4.5%.
