品种杨基因收集圃品种(系)适应性评价研究

The breed adaptation evaluation research of breed poplar gene collection garden

在吉林省双辽黑钙土型沙土上建立品种杨基因收集圃并进行适应性栽培试验,结果表明:在88个品种(系)中,苗期(1 a生)成活率大于对照白城小黑杨(85.3%)的有10个品种,分别为晚花杨(94.0%)、新生×小黑52杨(91.3%)、白城41号杨(88.7%)、83-25杨(87.4%)、莫斯科加拿大杨(86.7%)、加×美杨(86.7%)、88-04杨(86.7%)、98-33杨(86.7%)、黑林2号杨(86.7%)、小×钻杨(85.6%)。半轮伐期(12 a生)保存率大于对照白城小黑杨(85.33%)的有2个品种,分别为7915501杨(91.67%)和白林3号杨(87.50%);与对照表现持平的有1个品种,即新生×小黑52杨(85.33%)。

The breed poplar gene collection garden was established and the adaptation cultivation experiment was carried in chernozem sandy soil of Shuangliao city Jilin province.The result showed that there were 10 breeds whose seedling stage （1 year） rate of survival was greater than the control Populus simonii ×P.nigra cv.‘Baicheng’ whose rate of survival was 85.3%.They were Populus ×eurameicana cv.‘Serotina’ （94.0%）,Populus ×cv.＇Xinsheng ×xiaohei -52＇（91.3%）, Populus ×cv.＇Baicheng-41＇（88.7%）,Populus‘83-25’（87.4%）, Populus‘Mosike jianada’（86.7%）, Populus cv.＇Jia ×mei＇（ 86.7%） , Populus‘88 -04 ’ （ 86.7%） , Populus‘98 -33 ’ （ 86.7%） , （ Populus simonii ×Populus nigra ） × （Populus nigra ×Populus simonii） cl.＇Heilin Ⅱ＇（86.7%）, Populus simonii ×Populus pyramidolis cv.xiaozuan （85.6%） ,respectively.There were 2 breeds whose half rotation （12 years） preserving rate was higher than control Popu-lus simonii ×P.nigra cv.‘Baicheng’whose preserving rate was 85.33%.They were Populus‘7915501’（91.67%）and Populus ×cv.＇Bailin-3＇（87.50%）.There was one breed whose expression was steady with control.It was Populus ×cv.＇Xinsheng ×xiaohei -52＇（85.33%）.
