‘乐亭白黄瓜’是河北乐亭县日光温室越冬茬旱黄瓜基地主栽的农家品种,由于缺乏系统选育,品种性状混杂,制约了当地旱黄瓜产业健康发展。现以‘乐亭白黄瓜’为试材,在春季日光温室栽培条件下,对该原始群体的生长势、早熟性、产量和品质等性状进行了调查分析。结果表明:‘乐亭白黄瓜’栽培群体的植株分枝少,但株高和节间长度分离较严重,变异系数分别为33.7%和20.9%。第一雌花节位集中分布在第4~11节;20节内雌花节位数集中分布在2~4个,变异系数27.4%。初步鉴定单性结实力较弱。商品瓜棒状,瓜长度集中分布在20~25cm,变异系数15.1%;瓜皮色均匀一致的占25.7%。雌花花柄长度变异系数为45.0%。该研究结果为黄瓜新品种选育提供参考依据。
Laoting White Cucumber is a farmhouse cultivated in wintering cucumber field in the solar greenhouse of Laoting County, Hebei Province. Due to the lack of systematic breeding and variety traits, the healthy development of the local dry cucumber industry has been restricted. In this paper, we studied the growth potential, the early maturity, the yield and the quality of the original population under the greenhouse cultivation conditions of “Laoting White Cucumber” in the spring. The results showed that the plantlets of “Laoting White Cucumber” had few branches, but the plant height and internode length were more severely separated with the coefficient of variation of 33.7% and 20.9% respectively. The first female flower node was concentrated in the fourth to the 11th; the female node number in the 20th was concentrated in 2 ~ 4, the coefficient of variation was 27.4%. Preliminary identification of unisex strength is weak. Commodity melon stick-shaped, melon length concentrated in the distribution of 20 ~ 25cm, coefficient of variation of 15.1%; melon skin color uniform accounted for 25.7%. The coefficient of variation of flower length of female flower was 45.0%. The results provide a reference for the breeding of new cucumber varieties.
