Abstract Twisted trunks are not uncommon in trees, but their effects on tree growth still unclear. Among coniferous species, the phenomenon of trunk distortion P. yunnanensis is more prominent.

Abstract Twisted trunks are not uncommon in trees, but their effects on tree growth still unclear. Among coniferous species, the phenomenon of trunk distortion is more prominent Pinus yunnanensis . To expand germplasm genetic resources, we selected families with excellent phenotypic traits to provide material for advanced generation breeding. The progeny test containing 93 superior (3240 trees) was used as research material. Phenotypic measurements and estimated parameters (family heritability, realistic gain gain) were performed at 9, 15, 18 years age, respectively. evaluation yielded following results (1) intra-family variance component plant height (PH) greater than that inter-family, while inter-family components other (diameter breast (DBH), crown diameter (CD), under branches (HUB), degree stem-straightness (DS)) intra-family, indicating there abundant variation among potential selection. (2) At half rotation period (18 old), a significant correlation traits. proportion trees twisted (level 1–3 straightness) reached 48%. DS significantly affected traits, which PH DBH most affected. volume loss rate caused by 18.06-56.75%, implying could be completely eliminated after an artificial (3) influence shape, width, increased, early-late between PH, extremely significant. range coefficient variation, family heritability (PH, DBH, volume) 44.29-127.13%, 22.88-60.87%, 0.79–0.83, (4) A total 21 method membership function combined independent Compared mid-term selection accuracy early (9 old) 77.5%. families’ 5.79-19.82% 7.12-24.27%, This study can some useful reference breeding species.
