Tomato breeding method and fruit vinegar brewing method

Abstract

The invention relates to a tomato breeding method and a method for brewing fruit vinegar, and particularly relates to a tomato strain breeding method which comprises the following steps: screening 3-5 seeds of excellent single plants from a selfing separation offspring F2 generation of F1, blanching the seeds for 3 minutes by hot water at 60 DEG C, continuously soaking for 5 hours, sowing, and cultivating 2-3 seedlings with 6-8 true leaves for each offspring; the seedlings cultivated in the first step are transplanted in an exercising mode, and one robust seedling is transplanted from excellent single-plant offspring; when the inflorescence of the rice seedlings in the step 2 appears, pinching is performed for 3-5 days, and 2-3 full flower buds are reserved; when the flower buds reserved in the step 3 bloom, the plants are vibrated, and a fruit with a normal shape is selected and reserved; when the fruits in the step 4 turn color, collecting seeds to obtain F3-generation seeds, slightly rubbing the F3-generation seeds with fine sand, and performing sowing and seedling raising again; repeating the steps 1-5, continuously sowing and selfing for more than 6 generations. According to the breeding method disclosed by the invention, the breeding cost is effectively reduced, and six generations can be bred in two years; the tomato fruit vinegar brewed by the method is strong in natural fragrance, safe and nutritional.

Description

technical field [0001] The invention relates to the field of vegetable breeding and product processing, in particular to a tomato breeding method and a method for brewing fruit vinegar. Background technique [0002] In the traditional tomato breeding process, multi-generation mixed seed collection and pedigree selection methods are mostly used, which have problems such as large planting groups, large land use, long cycle, more labor, time-consuming and laborious, and poor selection effects; After multiple generations of selection, there are serious diseases caused by conventional seedling breeding. At the same time, after multiple generations of selection, the genetic population is likely to decrease, which in turn affects the selection effect. Based on this, we have studied a tomato breeding method with short time, fast breeding speed, significantly improved selection efficiency and preservation of selection scale. A series of different colors, different hardness and differ...

Problems solved by technology

[0003] At present, most of the fruit vinegars sold on the market have been tested to have high formaldehyde content and are not suitable for direct drinking. Therefore, it is necessary to screen the cultivated varieties to find tomato varieties suitable for brewing drinks, and to develop a low formaldehyde content that can It is an urgent problem to be solved by relevant personnel in the field to brew tomato fruit vinegar that can be drunk directly, and produce a nutritious and healthy tomato drink with strong aroma, no added other flavors and pigments, and safety.
