| 摘 要： | 经8a定位观察分析发现，红松初级种子园中各无性系结实量差异极显著，这种差异由遗传因素控制，经计算筛选出的结实高产无性系平均增益达51.38%，比对照增产60%以上，结实高产无性系并未影响生产性状和种子质量指标，由此可证明红松选择育种将结实性状作为选择指标。具有很大的经济潜力。

| Abstract: | Through eight-year-long-term research and analysis. the authors found that the yield of every clone in Korean pine seed orchard was extremely different. The difference is controlled by genetic factors. The seed gain of the selected high-yield clones was 51. 38 percent and was 60 percent higher 'than that of contrast. However. the clones didn't influence the growth characters and seed quality. The test proved that it has great economic potential that tile fruition character is regarded as tile final goal in Korean pine selection breeding. |
