寒地杨树新品种遗传稳定性与适应性分析评价

摘要

利用Wricke、Eberhart、Tai、Pithus模型估算11项评价参数,进行杨树新品种(系)树高生长性状生产力、遗传稳定性和生长适应性评价.结果表明,5、53号杨遗传稳定性高,适应性好,属中高产型品种；50和J号杨适应性较好,遗传稳定性一般,生产力水平高,属高产型品种.B号杨遗传稳定性高,适应较好的环境条件,属中产型品种.%A study was performed to evaluate productivity, genetic stability and adaptability of new popular clones by means of 11 parameters calculated by Wricke, Eberhart, Tai and Pithus models. Results showed that clones No. 5 and No. 53 performed well in terms of genetic stability and adaptability, belonging to the type of super high productivity. Clones No. 50 and J exhibited good performance in genetic stability and adaptability, belonging to the type of high productivity. Clone B performed well in genetic stability, belonging to the type of medium productivity.
