Scientists at the USDA, ARS, U.S. Vegetable Laboratory in Charleston, SC evaluated the USDA, ARS citron watermelon germplasm collection for flowering time and fruit yield traits under field conditions over two years. They used a “genome-wide association study (GWAS)” to detect genomic regions and molecular (DNA) markers associated with flowering time and fruit yield traits. The new molecular markers will be useful in improving watermelon varieties for early flowering and maturity and yield performance via marker-assisted breeding.
A super-pangenome was constructed to represent the entire watermelon gene repertoire, uncovering several disease resistance genes that are present in wild watermelons while completely lost in watermelon cultivars.
Editors of the Cucurbit Genetics Cooperative are now accepting reports for CGC #47. Reports or manuscripts should be submitted by February 15th, 2024. The CGC committee seeks assistant editors for future CGC reports.
Scientists have constructed a comprehensive ‘super-pangenome’ for watermelon and its wild relatives, uncovering beneficial genes lost during domestication that could improve disease resistance and fruit quality of this vital fruit crop.
