Population structure, genetic diversity and genome-wide association analysis of the seed morphology traits in Handroanthus chrysanthus (Jacq.) s.o.grose.

Abstract excerpt

BACKGROUND: Handroanthus chrysanthus is a remarkable landscape tree species with significant research and development potential. However, it remains unclear whether the varieties introduced to China are one species or two species. Since the morphological characteristics of seeds are extremely valuable in plant systematics research, in this work, 126 germplasm samples of H. chrysanthus were genotyped by...
