Abstract: ‘Jinghu CRV4’ is a new summer squash F₁ hybrid bred by crossing inbred line‘ 08-19-15-29-18-20-58’ as female parent with‘ 06-2-6-38-15-26-18’ as male parent. It was developed by combining marker-assisted selection technology with traditional breeding methods. It is an early maturing variety with mid-vigorous plant growth，short nods and continuous fruit setting ability. Its fruit has glossy light green rind. The plant is of mid-tall cylinder shape with straight and equal size fruit. It is tolerant to high temperature and not easy to premature aging.
