当前,瓜果类蔬菜的杂优利用工作正在逢勃开展,如何发挥瓜果类蔬菜杂种优势效益,正确选配适合本地生产及商品性要求,能提高品质,有显著增产作用的杂交组合是一个重要的关键问题。我区各社、队蔬菜科研所(站),在78、79两年的实践中,做了大量选配杂交组合的试验、探索工作,经品种对比和小区生产鉴定,从十多种瓜、果蔬菜的的20余个杂交组合中,初步评选出四个杂种优势明显、较适合我市推广应用的杂交组合,现介绍于下。 几个较好的瓜果类蔬菜杂交组合 1、南京早椒×茄门甜椒(简称早×甜)。该组合由南京引进,在我市反映良好,生长势强,苗期繁茂,株型大而紧凑,根系发达,茎杆粗壮,叶绿色,果大、肉厚呈中间型,辣味较母本弱,品质及商品性能均好。经多点组合对比试验,产量名列第一,一般亩产3,500斤,高者达5,000余斤,较母本增产63～75％,较父本增产二
At present, the utilization of hybrid fruits and vegetables is flourishing, how to play the heterosis of fruits and vegetables, the correct selection of suitable for local production and commercial requirements, can improve the quality of a significant increase in yield of the hybrid combination is a Important key issue. In our practice, a large number of experiments were carried out on various combinations of hybrids to explore the work of the community and team vegetable research institutes (stations) in 78 and 79 years. Based on the comparison of cultivars and identification of community production, from a dozen of melons and fruits Vegetables more than 20 hybrid combinations, initially identified four hybrids obvious advantages, more suitable for the city to promote the use of hybrid combinations, are introduced below. A few good fruits and vegetables hybrids 1, Nanjing early pepper × solanum bell pepper (referred to as early × sweet). The combination was introduced from Nanjing and showed a good growth in our city with strong growth potential and seedling stage. The plant type was large and compact with well-developed root system, thick stalks, green leaves, Weak, quality and product performance are good. The multi-point combination of comparative tests, the output ranked first, generally 3,500 pounds per mu, the highest amounted to more than 5,000 pounds, 63 to 75% increase over the female parent,
