红松半同胞家系遗传变异分析及果材兼用优良家系选择

以临江林业局闹枝林场内48个红松半同胞家系为材料,连续3年对其生长性状进行测定分析。本研究中评价选出的优良家系可为红松良种登记提供材料,选择方法为其它果材兼用树种良种选育提供理论基础。Forty-eight half-sib families of Korean pine (Pinus koraiensis) sourced from Naozhi Forest Farm of Linjiang Forestry Bureau were employed as experimental materials. Their growth traits were measured and analyzed over a consecutive three-year period. The elite families selected and evaluated in this study can provide candidate materials for the registration of improved Korean pine varieties, and the applied selection method also offers a theoretical foundation for the elite breeding of other dual-purpose tree species for both fruit and timber.
