Genetic diversity and structure of the 4^th cycle breeding population of Chinese fir (Cunninghamia lanceolata (lamb.) hook).

ABSTRACT: Studying population genetic structure and diversity is crucial for the marker-assisted selection and breeding of coniferous tree species. In this study, using RAD-seq technology, we developed 343,644 high-quality single nucleotide polymorphism (SNP) markers to resolve the genetic diversity and population genetic structure of 233 Chinese fir selected individuals from the 4^th cycle breeding program, representing different breeding generations and provenances. The genetic diversity of the 4^th cycle breeding population was high with nucleotide diversity (P_i ) of 0.003, and H_o and H_e of 0.215 and 0.233, respectively, indicating that the breeding population has a broad genetic base. The genetic differentiation level betw
