Identification of phenological QTLs using a combination of high- and low-coverage whole genome sequencing in Japanese plum (<i>Prunus salicina</i> Lindl.).

ABSTRACT: The genetic control of phenological traits in Japanese plum (Prunus salicina Lindl.) was investigated through quantitative trait loci (QTL) analysis in three segregating F₁ populations: 'Black Splendor' × 'Pioneer' (BS×PIO), 'Red Beaut' × 'Black Splendor' (RB×BS), and 'Red Beaut' × 'Santa Rosa Precoz' (RB×SRP), comprising 121, 103, and 103 seedlings, respectively. Whole-genome sequencing (~80×) was conducted for the four parents, and progenies were genotyped using a cost-efficient reduced-representation sequencing strategy. SNPs heterozygous in one parent and homozygous in the other were used to build six parental linkage maps. Phenological traits, including beginning, full, and end of flowering (BF, FF, EF), flowering intensity (FI), ripening date (RD), fruit development
