Melon genome with hundreds of DNA markers has been mapped by researchers from Texas A&M University.

The results were reported in Journal of the American Society of Horticultural Sciences. 

Texan researchers located genetic markers linked to fruit sugars, ascorbic acid (vitamin C) and male sterility, which is useful for developing hybrid varieties.

They said the genetic map will be helpful for future studies in identifying fruit sweetness, quality, size, shape, and resistance to diseases.
