The department is divided into four breeding groups including cucumber, melon, squash and watermelon.  We focus on cucurbit vegetable crops germplasm collection, preservation and evaluation; genetic  analysis and candidate gene mining of disease resistance, stress tolerance and quality related traits;  functional molecular marker development of the important agronomic traits; haploid and polyploid tissue  culture technology study; gene transformation, gene editing technology study; and elite material  development and new variety breeding of high quality, multi resistance, green and efficient.
