Breeding of a new pumpkin cultivar Xinpin 1 for eating and processing dual-purpose.

【Objective】A new pumpkin cultivar called Xinpin 1 for eating and processing dual-purpose was bred to provide technical support for selecting superior pumpkin cultivars in Guangxi. 【Method】The female parent, inbred line YP, was derived from directional nine-generation selfing of Yipin pumpkin hybrid variety. The male parent, inbred line RT, was derived from eight-generation selfing of greenish-white pumpkin. The female parent was crossed with male parent, and variety comparison and production demonstration telts were carried out afterwards. 【Result 】The newly bred Xinpin 1 was proper both for eating and processing. The fruit was oval. Single fruit weight was 1.00-2.00 kg. The atrovirens pericarp had light-color spots and pulp was orange-yellow with the thickness of 2.0-3.0 cm. With less water,starch and total sugar content was 18.0% and 3.01%, respectively. It tasted smooth and sweet with chestnut flavor. Due to tenacious pulp, it was resistant in transport. Only 65 days were required from sowing to tender pumpkin harvest and another 20 days for mature pumpkin harvest. The mean yield in variety comparison test was 24564.0 kg/ha, and it was22440.0-25299.0 kg/ha in production demonstration. 【Conclusion】Having outstanding yield and quality traits, Xinpin 1can be extended as an early cultivation cultivar in winter and spring for Guangxi pumpkin planting area.
