摘要

玉兔是以 H25 为母本、L04 为父本选育而成的杂交 1 代丝瓜新品种。该品种属早中熟品种，从播种到初收春季约 60 d、秋季约 45 d。植株生长势强、连续坐果能力强。瓜圆筒形、皮翠绿色、无棱沟，瓜长 21.2~22.0 cm, 果实横径 7.7~7.9 cm, 单瓜质量约 740 g, 667 m²产量 2400 kg 左右。可溶性固形物含量(w,后同)4.8%，粗蛋白含量 0.71%，粗纤维含量 0.1%，维生素 C 含量 57.0 mg·kg^-1。丰产性和商品性好，品质优良。人工接种鉴定表现高抗疫病。适宜广东省春、秋种植。2023 年通过广东省农作物品种审定委员会评定。

Abstract

Yutu is a new F1 hybrid loofah variety bred with H25 as the female parent and L04 as the male parent. This hybrid is early to medium maturity variety, with strong plant growth potential and strong continuous fruit setting ability. From sowing to initial harvest, it takes about 60 days in spring and 45 days in autumn. The fruit is cylindrical in shape, with emerald green skin and no furrows. It is 21.2-22.0 cm in length and 7.7-7.9 cm in diameter, and single fruit mass is 740 g approximately. The output of 667 square meters is about 2400 kg. The content of soluble solids is 4.8%, the content of crude protein is 0.71%, and the content of crude fiber is 0.1%, the content of vitamin C is 57.0 mg·kg ^-1. The variety has high yield and marketability, with excellent quality. Artificial inoculation identification shows high resistance to blight.
