摘要： Plant appearance is one of the most important characteristics affecting consumption and breeding choices. In watermelon, except for the normal phenotypes such as the basic foreground pattern (solid/stripe), background pattern (yellow/green rind), and fruit shape (round/oblong), there was a novel and unique appearance called 'moon and star' trait with big and tiny yellow spots on the fruit rind. Following a dominant inheritance pattern, the attracting appearance is convenient for variety breeding. The result of this study revealed that the chlorophyll content dramatically decreased and chloroplast structure significantly changed for the yellow spot, which were supposed to be the direct reason for fruit color change. Contrary to a previous study, genetic analysis showed that there were two interacting genes responsible for this novel trait. Using bulk segregant analysis, two candidate regions located on chromosome 1 and 8 were identified to contain these two genes regulating the 'moon and star' trait.
