Analysis on open-pollination progenies from clonal seed orchard of Pinus massoniana and combination ability selection
摘要
Abstract
A half-sib progeny test was conducted on diameter at breast height(DBH) , tree height and stem volume of 48 9-year-old families of Pinus massoniana from Duyun Masson Pine Clonal Seed Orchard . The results indicated there was great significant difference among families in tree height, DBH and volume, the heritability was high. 9 families were selected, the average tree height, average DBH, average individual volume was 7. 12 m, 9. 84 cm, 0. 037 97 m , and the genetic gain was 10. 44% , 7. 73% and 20. 80% respectively. The 46 excellent individuals were selected from the 9 excellent families, the average height, average DBH and average individual volume increased 53. 81% ,56. 65% and 150. 18% respectively, the genetic gain of individual volume was 55. 05% . They could be used as materials in building seed orchard of high cycle in Guizhou province.关键词
