Polyploidization is one of the important driving forces of speciation and crop domestication. Polyploidization is widely employed in the research and application of crops because it can greatly enrich the diversity in a very short period of time. Crop improvement using polyploidization has been successful in watermelon, cucumber, melon and other important Cucurbitaceae crops. Recent studies have shown that polyploids often have distinct environmental fitness advantages. With the increasingly serious of climate problems nowadays, improving the environmental adaptability of Cucurbitaceae crops via polyploidy has become one of the essential contents of Cucurbitaceae crop breeding. According to the genome composition, polyploids are divided into autopolyploids and allopolyploids. Most of the previous studies on Cucurbitaceae crops only focused on autopolyploid, and the understanding and research on allopolyploid were obviously lacking, which needed further development and utilization. Meanwhile, along with the advancement of genome sequencing technology and the rapid development of various omics and molecular biology technologies, many important progresses have been made in plant polyploidy research, which provides unprecedented opportunity for research on polyploidy-related mechanisms in Cucurbitaceae crops. This paper systematically reviewed the recent research and application on polyploidy in Cucurbitaceae crops, aiming to explore the development and future of polyploidy in the breeding of Cucurbitaceae crops, and providing a reference for the genetic breeding of cucurbit and other crops.
