Genetic Variation in the Main Cultivar Collection of <i>Castanea henryi</i> Revealed by Genome Resequencing.

ABSTRACT: Castanea henryi is an important economic tree species in China. Its nutrient-rich nuts play a key role in raising farmers' income in mountainous areas, promoting forestry industry development, and maintaining ecological balance, thereby providing significant economic and ecological value. To systematically elucidate the genetic characteristics of major C. henryi cultivars in China, this study conducted phenotypic trait measurements on 42 cultivars collected from Taining and Jian'ou in Fujian Province. Combined with whole-genome resequencing technology and using the C. henryi genome as a reference, systematic analyses were carried out. The results indicated that the Jian'ou group (HJO) generally exhibited superior performance in key fruit phenotypic traits compared to t
