Genome-wide association analysis provides molecular insights into the natural variation of watermelon seed size.

ABSTRACT: Seed-consumption watermelon tend to have larger-sized seeds, while flesh-consumed watermelon often require relatively smaller seed. Therefore, the seed size of watermelon has received extensive attention from consumers and breeders. However, the study on the natural variation and genetic mechanism of watermelon seed size is not clear enough. In the present study, 100 seed weight, seed hilum length, seed length, seed width, and seed thickness in 197 watermelon accessions were examined. Furthermore, association analysis was conducted between seed size traits and high-quality SNP data. The results revealed that there was a strong correlation between the five seed traits. And seed enlargement was an important feature during watermelon seed size domestication. Meanwhile, the seed consumption bi
