GWAS combined with transcriptomics revealed key regulatory genes for inflorescence traits and fruit set rate in Litchi (Litchi chinensis Sonn.).

ABSTRACT: As an important tropical and subtropical fruit, litchi's inflorescence size and the number of florets per inflorescence are crucial factors affecting fruit set rate and yield. This study extensively collected a total of 219 litchi germplasm resources, including those from China and 11 other countries worldwide, systematically evaluating eight core phenotypic traits: inflorescence length (IL), inflorescence width (IW), number of secondary lateral inflorescences (NSLI), number of inflorescence internodes (NII), base to main axis length (BMAL), inverted 5th internode length (I5IL), number of female flowers per inflorescence (NFFI), and fertilization rate (FR). The research findings indicated significant correlations between these agronomic traits and fruit set rate, particularly with high fru
