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5 a生单株材积达到0.218 24 m3,0.241 3 m3,0.218 2 m3,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。
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 0.218 2 m3 ,0.241 3 m3 and 0.218 2 m3 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 .
