Embodiment 1

[0073] The breeding method of the present embodiment comprises the following steps:

[0074] 1) Breeding of female parent

[0075] Chunxuehong is an unlimited-growing pink tomato cultivated by Syngenta. The plant is sprawling, robust, and has strong comprehensive disease resistance. It is resistant to tomato yellow leafroll virus (anti-TY) and root-knot nematode. The fruit is pink, with a smooth fruit surface, slightly flattened fruit shape, and green fruit shoulders. The weight of a single fruit is 250-300g, and it has strong continuous fruiting ability. The fruit has high soluble solid content, less fiber, moderate sweet-sour ratio and good taste.

[0076] With Chunxuehong as the original resource, it was planted in cold sheds in early spring and summer sowing for 4 years. After 7 generations, a high-generation inbred line female parent was bred. The plants of this line grow robustly, resist TY and root-knot nematodes, Strong continuous fruit setting ability and good fruit...

Embodiment 2

[0100] The breeding method of the present embodiment comprises the following steps:

[0101] 1) Breeding of female parent

[0102] Chunxuehong is an unlimited-growing pink tomato cultivated by Syngenta. The plant is sprawling, robust, and has strong comprehensive disease resistance. It is resistant to tomato yellow leafroll virus (anti-TY) and root-knot nematode. The fruit is pink, with a smooth fruit surface, slightly flattened fruit shape, and green fruit shoulders. The weight of a single fruit is 250-300g, and it has strong continuous fruiting ability. The fruit has high soluble solid content, less fiber, moderate sweet-sour ratio and good taste.

[0103] With Chunxuehong as the original resource, it was planted in cold sheds in early spring and summer sowing for 4 years. After 7 generations, a high-generation inbred line female parent was bred. The plants of this line grow robustly, resist TY and root-knot nematodes, Strong continuous fruit setting ability and good fruit...

Embodiment 3

[0127] The breeding method of the present embodiment comprises the following steps:

[0128] 1) Breeding of female parent

[0129] Chunxuehong is an unlimited-growing pink tomato cultivated by Syngenta. The plant is sprawling, robust, and has strong comprehensive disease resistance. It is resistant to tomato yellow leafroll virus (anti-TY) and root-knot nematode. The fruit is pink, with a smooth fruit surface, slightly flattened fruit shape, and green fruit shoulders. The weight of a single fruit is 250-300g, and it has strong continuous fruiting ability. The fruit has high soluble solid content, less fiber, moderate sweet-sour ratio and good taste.

[0130] With Chunxuehong as the original resource, it was planted in cold sheds in early spring and summer sowing for 4 years. After 7 generations, a high-generation inbred line female parent was bred. The plants of this line grow robustly, resist TY and root-knot nematodes, Strong continuous fruit setting ability and good fruit...

Abstract

The invention relates to a breeding method of a good-taste and transport-and-storage-resistant pink tomato. The breeding method of the good-taste and transport-and-storage-resistant pink tomato comprises the following steps of taking Chunxuehong tomato as the female parent to perform 7 generations of individual selection and mixed seed reservation; taking Difenni tomato as the male parent to perform 4 generations of individual selection through a continuous selfing and molecular marker-assisted selection method to obtain 4th-generation strains, then combining tomato yellow leaf curl disease-resistant virus and performing 2 generations of individual selection to obtain 6th-generation strains, performing 2 generations of individual selection, removing abnormal plants and performing mixed seed reservation; crossing the female parent and the male parent to obtain seeds of the good-taste and transport-and-storage-resistant pink tomato. The bred good-taste and transport-and-storage-resistantpink tomato has the advantages of being good in taste, high in sugar degree, regular in fruit shape, good in color, resistant to transport and storage, robust in plant growth, high in comprehensive disease resistance and the like.

Description

technical field [0001] The invention relates to the technical field of tomato breeding and cultivation, in particular to a breeding method for fine-quality pink tomato with good taste, storage and transportation resistance. Background technique [0002] Tomato, namely tomato (scientific name: Lycopersicon esculentum Mill.), is a kind of annual or perennial herbaceous plant of Solanaceae tomato genus, originated in South America. Tomato is a food that belongs to both vegetables and fruits. It has high nutritional value and is rich in vitamins, dietary fiber, minerals, organic acids and antioxidants. Tomatoes have the advantages of many varieties, high yield, rich nutrition and wide application. In addition, whether tomato is paired with other foods, or boiled in soup, stir-fried, etc., it has the effect of improving flavor, freshness, and embellishment. Therefore, it is deeply loved by people, and its demand is constantly increasing, and the planting area is also expanding. ...
