杨树杂交品种汉杨2号、汉杨3号、汉杨8号的选育初报

Breeding of Hybrid Poplar Varieties of Hanyang 2nd, Hanyang 3rd and Hanyang 8th

摘要:

摘要：经过12年研究，选育出“汉杨2号”（鲁山杨×圣山杨）、“汉杨3号”（I-69杨×鲁山杨）、“汉杨8号”（圣山杨×鲁山杨）等3个杨树杂交新品种，其5a生单株材积达到0.21824m3,0.2413m3,0.2182m3,其遗传增益为15.18%,26.08%,15.18%；通过初步试验结果，将进一步开展区域造林试验和推广应用。

Abstract:

Abstracts:Hybrid poplar Varieties of “Hanyang 2nd”,“Hanyang 3rd”and“Hanyang 8th”were selected for twelve years and their five-year-old individual timber volumes were 0.2182m3,0.2413m3 and 0.2182m3 respectively. The values of their genetic gains were 15.18%, 26.08% and 15.18%，and then we will carry out regional planting test and popularization and application by preliminary test.
