- 摘要:
- ‘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20~25 cm,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。
- Abstract:
- ‘Laoting white cucumber’is the main local variety cultivated in winter solar greenhouse in Laoting,Hebei.A large degree of variability due to insufficient system selection has restrained the development of cucumber industry.Plant vigor,precocity,fruit yield and quality of ‘Laoting white cucumber’ were investigated in a solar greenhouse in spring.The results showed that the plants were less branching but the coefficient of variability (CV) of plant height and internode length was 337% and 209%,respectively.The first pistillate flower bearing node was concentrated 4-11.The number of female flower nodes within 20 nodes was concentrated from 2 to 4,and the CV was 274%.The parthenocarpy was weak.The marketable fruit was club-shaped and the fruit length was concentrated at 20-25 cm.The percentage of fruit with uniform basal color was 257%.The CV of pedicel length of female flowers was 450%.These data could be helpful for the selection of elite cucumber cultivars.
