%X <em>Picea crassifolia</em> is an important native tree species because it has a strong adaptability in northwest China, plays an important role in soil and water conservation, urban and rural greening, and barren hill afforestation. For understanding the half-sibling seeds and their progeny seedlings phenotypic traits of <em>P. crassifolia</em> variation characteristics, we selected the half sibling seeds and its semi-half-sibling seedlings in eight years of superior individual trees as materials to analyze and compare different good family half-sibling seeds and its offspring seedling phenotypic traits. There were significant differences in the seed scales, seed wing and seed phenotypic traits of the half sibling seeds in <em>P. crassifolia</em>, and there were significant differences among families and within families(<em>P</em>&lt;0.01). There is a significant positive correlation between seed scale, seed longiness and kilo-grain weightiness of half sibs-seeds. The genetic heritability and genetic variation coefficients of the seedlings of the half-siblings of <em>P. crassifolia</em> were the greatest(0.951%, 19.14%) in seedling height, followed by the second(0.737%, 10.87%) in ground diameter, and the smallest in lateral branches(0.642%, 2.66%). The variation of phenotypic traits on half sibs-seeds and their offspring seedlings is mainly controlled by genetic factors and environmental factors.
