| 摘 要： | 以腾冲古永林场所设的９个云南松天然优良林分固定样地为参试单元，设大理、保山商品种作对照，进行滇西地区云南松天然优良林分半同胞子代测定试验。经７年试验，探讨了子测林生长、材质、结实诸性状的关系；估算了优良林分子代初期的实际遗传增益和主要遗传参数。结果显示：该区云南松天然优良林分子代７年生时树高、胸径、材积和木纹理扭转度的实际增益分别达到：３７．４９％、６５．６０％、２１９．８４％和２６９．５７％；遗传增益分别为：２０．１４％、４０．４６％、１０７．１１％和５９．７９％，已远远超过云南松天然优良林分子代遗传增益３％的攻关考核指标。通过试验反馈表明了所制定的滇西地区云南松天然优良林分选择方法及标准具有科学性和可靠性

| Abstract: | Taking 9 fixed sample plots of Pinus yunnanensis natural elite stand in Guyong Forest Farm in Tengchong County as test units and installing 2 commodity seeds of Dali and Baoshan as control, the half-sib progeny test on Pinus yunnanensis elite stand in west of Yunnan has been done. Through the test for 7 years, the relationship among the growth, timber quality and fruit bearing of filial generation forest has been investigated and the primary actual genetic gain and main genetic parameter of filial generation of elite stand has been estimated. |
