Screening method of high quality blueberry varieties

Abstract

The invention provides a screening method of high quality blueberry varieties. The screening method of the high quality blueberry varieties includes: (1) selecting 10 blueberry varieties excellent in characteristic from blueberry plants 3-5 years of full productive age, and respectively selecting fruits at maturation stages of the 10 blueberry varieties as samples to be measured; (2) respectively measuring content of anthocyanin, ursolic acid and pterostilbene of the samples to be measured; (3) measuring content of vitamin A, vitamin C and vitamin E of the samples to be measured; (4) measuring content of mineral elements of calcium, magnesium, iron, zinc, potassium, sodium, phosphorus, copper and manganese of the samples to be measured; (5) performing mathematical analysis on the measured data obtained through the above steps, and screening out blueberry varieties highest in edibleness from the blueberry plants as the high quality blueberry varieties. The screening method of the high quality blueberry varieties establishes a screening index system of the blueberry varieties, which can be quantitatively evaluated, can provide scientific instructions to blueberry screening and cultivation enlarging practical work, and is important in practical application value.

Description

technical field [0001] The invention belongs to the field of ecological breeding, and in particular relates to a screening method for high-quality blueberry varieties. Background technique [0002] Fresh fruit is a good product for people's daily consumption. Among them, berry fruits are closely related to human health and people's daily life, and emerging berry varieties are getting more and more attention as domestic emerging high-quality fruits. As a fresh fruit, blueberry has high traditional nutritional value such as energy, carbohydrates, protein, amino acids, fats, vitamins and minerals, and has become increasingly popular this year. However, there are many varieties of blueberries, and the nutrient content of different varieties of blueberries varies greatly. How to effectively optimize and screen blueberry varieties and select excellent varieties for expansion and cultivation according to different needs can maximize blueberry production and meet Nutritional needs ...

AI Technical Summary

Problems solved by technology

However, the research results only cover a small number of blueberry varieties and individual functions, and it is difficult to optimize the edible efficacy of blueberry varieties due to unilateral factors.

Therefore, there is no more comprehensive evaluation of the nutritional value and edible efficacy of blueberries, and the establishment of a complex index system, although comprehensively considered, is complicated in the formation process, complex in calculation, and slow in updating
