利用白城市林科院内长白松、黑松、樟子松和赤松的试验林,进行人工杂交育种试验,我们于1987年、1988年、1989年和1991年连续开展了杂交组合各有侧重的试验研究工作。经播种育苗保存的杂种植株近千棵。1998年11月我们对1989年春杂交育种试验,1995年春定植在大安市安广林场的8年生松树杂交育种试验林进行了生长情况调查。黑松×长白松30表现优良,不仅保存率高,而且生长迅速。应用推广前景可观。
Using the experimental forest of Changbai pine, Pinus thunbergii, Pinus sylvestris var. Mandshurica and Pinus koraiensis in Baicheng Academy of Forestry, we carried out artificial crossbreeding experiments. In 1987, 1988, 1989 and 1991, we carried out continuous experiments with emphasis on hybrid combinations research work. Nearly a thousand hybrid plants have been preserved by sowing seedlings. November 1998 We conducted a cross-breeding test in the spring of 1989, and the investigation of growth of the 8-year-old pine hybrid breeding trial planted in Anqiu Forest Farm of Da’an in the spring of 1995. Good performance of the black pine × Changbai 30 30, not only high preservation rate, but also rapid growth. App promotion prospects are considerable.
