Problems solved by technology

[0003] The traditional method of evaluating new strains of tea trees is to use Fuding Dabai tea as a comparison to identify indicators such as tea tree phenology, economic traits, and tea-making quality. Individual traits are outstanding, but overall traits are poor. For example, the selected Fuyun No. 6 has a strong growth potential, but the quality of tea production is poor; and stress resistance are extremely poor; some varieties germinate very early, but the survival rate of introduction is low
The reason for these phenomena is that there is no comprehensive evaluation of tea tree strains, so the selected varieties have poor comprehensive properties and cannot meet the needs of the tea industry

Embodiment 1

[0028] The comprehensive quality of eight varieties including Fuding Dabaicha, Huangkui, Jinxuan, Zhenong 117, Baihaozao, Chuancha No. 2, Jinjincha and Zhenong 113 introduced to Jiangxi tea area was evaluated.

[0029] 1) Identification of evaluation indicators: survival rate, growth potential, free amino acid content, tea polyphenol content, yield, one bud and one leaf stage, total score of tea making quality, drought tolerance, cold resistance, and insect resistance of 8 tea tree varieties 10 evaluation indicators such as sex were identified, and descriptive traits were assigned values. The results are shown in Table 1.

[0030] Table 1 Indicator identification results

[0031]

[0032]

[0033] 2) Data standardization processing: survival rate, growth potential, free amino acid content, yield, one bud one leaf stage, total score of tea making quality, drought tolerance, cold resistance, and insect resistance are positively correlated indicators, and the content of tea...

Embodiment 2

[0046] The comprehensive quality of 7 newly selected varieties including Gancha No.4, Fuzhou No.2, Wulu No.1, Yongxiu No.6, mutagenesis Fuding Dabai and Fuliang Quye No.1 were evaluated.

[0047] Evaluation index identification, data standardization processing and spider diagram drawing method are the same as in embodiment 1, and the drawing result of spider diagram is shown in figure 2 . See Table 4 for the spider diagram area of ​​each species.

[0048] The area of ​​the spider graph of each strain in table 4

[0049]

[0050] The comprehensive evaluation results of spider web diagram are Fuzhou No. 2﹥Fuliangjiaye No.1﹥Gancha No.4﹥Fuding Dabai Tea﹥Wulu No.1﹥Mutated Fuding Dabai﹥Yongxiu No.6, which is better than Fuding Dabai Tea in comprehensive quality The test lines are Fuzhou No. 2, Fulianghuaye No. 1, and Gancha No. 4. The performance of these three varieties in the regional test shows that Fuzhou No. 2 has large yield, strong resistance, and better tea quality. Fu...

Embodiment 3

[0052] The comprehensive quality of three newly selected lines including Yongxiu 6, Fuding Dabaicha and Fuzhou 2 were evaluated.

[0053] Evaluation index identification, data standardization processing and spider diagram drawing method are the same as in embodiment 1, and the drawing result of spider diagram is shown in image 3 .

[0054] from image 3 It can be clearly seen the size of the area formed by the indicators of each strain. When the size of the spider web diagram can be seen intuitively, there is no need to use the area calculation formula for calculation. The comprehensive evaluation result is Fuzhou No. 2 > Fuding Dabaicha﹥Yongxiu No.6. Fuzhou No. 2 is better than Fuding Dabaicha and Yongxiu No. 6 in the 9 indicators measured, so Fuzhou No. 2 has the best evaluation. Among the indicators of Yongxiu No. 6, only the content of tea polyphenols has higher data. , and the others are worse than the other two varieties, so the evaluation result is accurate. It can...

Abstract

The invention provides a tea tree variety comprehensive evaluation method utilizing a cobweb map, which takes Fuding white tea as a contrast, evaluation indexes consist of survival rate, growth vigor,free amino acid content, tea polyphenol content, yield, one-bud one-leaf period, total score of tea making quality, drought resistance, cold resistance and insect resistance, and the cobweb map is adopted for comprehensive evaluation. According to the evaluation method disclosed by the invention, the comprehensive quality of the tea tree varieties can be sorted, and the tea tree strains with excellent comprehensive quality can be screened.

Description

technical field [0001] The invention relates to a comprehensive evaluation method for tea tree varieties using a spider graph, in particular to a comprehensive evaluation method for screening excellent tea tree strains, and belongs to the field of tea tree variety selection and breeding. Background technique [0002] The variety of tea trees not only affects the yield, function, quality and resistance of tea, but also is the key to the research and development of tea products. There are many methods for the selection of tea tree varieties, including individual plant selection, cross-breeding, and systematic breeding. At present, the most used methods are systematic breeding and cross-breeding, which screen excellent individual plants from a large number of resources. Carry out seedling breeding, and then form new strains, carry out regional tests of new strains, and study their adaptability and suitability in various regions. There are many methods for resource evaluation. ...
