黄瓜新品种华青40的选育

Breeding of a novel cucumber cultivar Huaqing 40

摘要

华青40是以自交系CU1407165为母本、自交系CU1407230为父本杂交选育而成的黄瓜新品种。该品种植株长势旺盛，叶片中大，深绿色，节间适中，单性结实能力强；瓜长32 cm左右，瓜皮色深绿油亮，短把，密刺，瘤中小，蜡粉少，果肉浅绿，口感清脆，风味浓郁，商品性较好。667 m²产量3 657.6~4 512.2 kg。干物质含量(w,后同)8.4 g·100 g^-1，可溶性固形物含量3.1%，维生素C含量9 mg·100 g^-1，总糖含量1820 mg·100 g^-1。综合抗性较强，高抗黄瓜白粉病、黄瓜花叶病毒病(CMV)，适合春秋保护地种植。2023年通过农业农村部非主要农作物品种登记。

Abstract

Huaqing 40 is a combined hybrid that was developed from the inbred line CU 1407165 and CU 1407230 as the female and male parent, respectively. The new hybrid cucumber cultivar was selected through multiple trials of comparisons and selections. The cultivar is characterized by its vigorous growth, medium-sized and dark green leaves, moderate internodes, and high parthenocarpic fruit yield. The cucumber fruit length is about 32 cm with glossy skin, dark green, short stalk, thick thorns, small and medium-sized nodules, less waxed, light green flesh, good fertility, taste crisp, rich flavor, good commodity. Its yield is 3 657.6-4 512.2 kg per 667 m². The dry weight content (w) is 8.4 g · 100 g^-1 with 3.1% soluble solid content, 9 mg·100 g^-1 vitamin C content, and 1820 mg·100 g^-1 total sugar content. The novel cultivar is highly resistant to powdery mildew fungus and cucumber mosaic virus, suitable for facility cultivations in spring or autumn.
