Cultivation method of leaf-produced astaxanthin tomato

Abstract

The invention discloses a cultivation method of a new tomato variety Yun shrimp No.3. The new tomato variety Yun shrimp No.3 is obtained by taking Yun hybrid No.8 which is hybridized by taking 92-23-7A as a female parent and 94-5-12F as a male parent as a female parent and astaxanthin-producing engineering tomatoes Shrimp red No.1 as a male parent for hybridization, the astaxanthin in leaves can be extracted by using acetone, and the content of the astaxanthin can be detected by using a UPLC (Ultra Performance Liquid Chromatography) method. The Yun shrimp No.3 is combined with main excellent characteristics of the female and male parents, the disease resistance is strong, the fruit quality is good, and the astaxanthin yield is high. The new tomato variety Yun shrimp No. 3 has the main characteristics that the plant is in determinate growth, the plant height is about 130 cm, the plant is dark red, the growth is healthy and strong, and the disease resistance is strong; the stem is yellow green to light brown, the branching ability is very strong, and the leaf yield is high; the leaf shape is common, the leafstalk is yellow green to dark red, the leaves are dark red, and the average content of a dry matter-astaxanthin is up to 2.64 mg / g; the sepal is green to dark red, the radial corolla is orange-yellow to orange-red, the anther is orange to red, and the stigma and the survival young fruits are brownish red; the fruits are bright red, the neak is purple red and is round, the fruit shape index is 0.8 to 0.92, the fruit surface is smooth, the glossness is bright, the sarcocarp is thick, the number of carpels is 5 to 6, the hardness is large, the average single fruit weight is 180 g, and the maximum single fruit weight is 400 g.

Description

Technical field: [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for cultivating tomato plant hybrid varieties, and more specifically, relates to the hybridization of '92-23-7A' as the female parent and '94-5-12F' as the male parent. Za 8' was used as the female parent, and the astaxanthin-producing engineering tomato 'Xiahong 1' was used as the male parent to obtain a three-cross tomato variety 'Yunxia 3' with good fruit quality, strong disease resistance, and high astaxanthin-yielding leaves 'Cultivation method. Background technique: [0002] The female parent '92-23-7A' and the male parent '94-5-12F' of 'Yunza 8' are inbred lines independently selected by the Tomato Research Group of the College of Landscape Architecture and Horticulture, Yunnan Agricultural University. The fruit quality of the female parent '92-23-7A' is good, the fruit shape is good, and the individual is large. The male parent '94-5-12F' has high dise...
