摘要：Heartwood are mainly used as Castanopsis hystrix valuable wood, which play a vital role in determining the quality of wood for sales, value assessment, and consumption. There are two defects in the heartwood produced by C. hystrix commercial forests: a low proportion of heartwood, reducing the output of high-value wood, and the uneven color of the heartwood from red to reddish-brown, affecting its visual appearance and decorative performance. As these two defects seriously influence the quality of C. hystrix heartwood, breeding of high-yield and high-quality heartwood varieties is critical. The present study examined 20-year-old C. hystrix forests in Yulin, Liuzhou, and Pingxiang counties in China. Through analysis of the proportion, density, brightness L*, chroma a*, and chroma b* of heartwood, genetic variation in each trait was described, genetic parameters were estimated, and the genotype by environment interaction effect was clarified. The average value of the above traits were 34.76%, 0.67 g/cm3, 52.22, 13.90, and 17.25, respectively. The results of the joint three-site variance analysis reveal that heartwood proportion, density, chroma a*, chroma b* have significant (p ? 2023 Elsevier B.V.
