Key Points

Investigate the differences in wood quality and growth traits between populations with varying degrees of basal bending in Picea glehnii.
Conducted an assessment in two test forests with varying levels of basal bending.
Evaluated wood quality using pyloric penetration measurements and growth traits using diameter at breast height (DBH) at 20 years.
Applied an ordered logit model to analyze the effects of wood traits on basal bending.
Populations with less basal bending showed significantly lower pyloric penetration values at approximately 30 years of age.
Higher DBH measurements were significantly associated with reduced basal bending at 20 years.
Breeding values for both traits had a significant positive regression coefficient, suggesting selectivity for individuals excelling in both traits is feasible.

Assesses wood quality and growth traits related to basal bending in Picea glehnii, indicating potential for effective breeding.
