摘　　要：【目的】选育鲜食、加工兼用型南瓜新品种,为广西南瓜生产提供良种选择和技术支撑。【方法】以一品南瓜杂交种一代经过9代连续自交定向分离的自交系YP为母本、日本甜粟杂交绿白皮色南瓜材料经8代自交提纯的高世代自交系RT为父本进行配组杂交,并进行品种比较试验和生产试验示范。【结果】选育成的鲜食加工兼用南瓜＂新品一号＂,果实扁圆形,单瓜重1.00-2.00 kg,果皮墨绿色布有浅色小点,果肉橙黄色,果肉厚2.0-3.0 cm,含水量少,淀粉含量18.0%,总糖含量3.01%,口感粉甜带板栗风味;果肉硬韧,耐贮运;从播种至采收嫩瓜仅需65 d,老熟瓜需85 d,品种比较试验平均产量24564.0 kg/ha,生产试验平均产量22440.0-25299.0 kg/ha。【结论】＂新品一号＂南瓜产量和品质等综合性状突出,可作为鲜食、加工兼用型南瓜新品种在广西南瓜种植区作冬春季大田露地提早栽培推广品种。[Objective]A new pumpkin cultivar called Xinpin 1 for eating and processing dual-purpose was bred to provide technical support for selecting superior pumpkin cuhivars in Guangxi. [Method]The female parent, inbred line YP, was derived from directional nine-generation selling of Yipin pumpkin hybrid variety. The male parent, inbred line RT, was derived from eight-generation selling 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 a- trovirens 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 was 22440.0-25299.0 kg/ha in production demonstration. [Conclusion ]Having outstanding yield and quality traits, Xinpin 1 can be extended as an early cultivation cultivar in winter and spring for Guangxi pumpkin planting area.
