A 2.9 Mb Chromosomal Segment Deletion Is Responsible for Early Ripening and Deep Red Fruit in .

Sweet orange () is an economically important fruit crop worldwide. Mining for genes associated with ripening periods and fruit color traits is crucial for plant genetics and for the improvement of external fruit quality traits. The present study identified a novel navel orange accession, designated as Ganhong, with early ripening and deep red fruit traits.
