a Nucleotide diversity (π) of sand pears in landrace (n = 231) and improved (n = 81) groups. For each box plot, the lower and upper bounds of the box indicate the first and third quartiles, respectively, and the center line indicates the median. The whisker represents 1.5× interquartile range of the lower or upper quartile. b LD in the landrace and improved groups. c Selective sweep regions during sand pear improvement (landrace vs improved groups) detected by CLR. The horizontal dashed line refers to the top 5% threshold of CLR scores. d Selective sweep regions during sand pear improvement (landrace vs improved groups) by π ratios. The horizontal dashed line refers to the top 15% threshold of πLandrace/πImproved. Fruit quality-related traits, stone cell content, coverage ratio of fruit russet, and fruit skin color, are demonstrated in the combined selective sweep regions.
