Problems solved by technology

But the breeding cycle of celery male sterile line is long, the technology is complicated, and there are also problems such as the difficulty in removing 50% of the fertile plants in time and thoroughly so that the purity of the hybrid cannot be guaranteed.
At the same time, the purity of celery hybrids produced by male sterile lines cannot be identified at the seedling stage.

Embodiment 1

[0019] Yellow 9816×Ventura 9701

[0020] ↓

[0021] Shuofeng No. 1 (F 1 hybrid)

[0022] (Solid, thick petiole, crisp and tender, good quality, resistant to bolting, relatively heat-resistant, and the yield is 16% higher than the main variety "Ventura" in production.)

[0023] Hybrid seed production is divided into two parts: parental seed production and hybrid seed production:

[0024] 1. Parental seed production technology

[0025] (1) Reproduction of female parent Huang 9816

[0026] The adult plant seed collection method must be used for seed collection, and the parents must be strictly selected and eliminated. During natural pollination seed collection, there must not be other celery varieties within 2000 meters in the female parent breeding area.

[0027] (2) Breeding of the parent Ventura 9701 inbred line

[0028] The seed collection method of the male parent is the same as that of common celery varieties. Isolation and other requirements are the same as the mot...

Embodiment 2

[0036] Yellow 9816×Jin 9606

[0037] ↓

[0038] Shuofeng 2 (F 1 hybrid)

[0039] (Plant height, solid, thick and long petiole, good quality, anti-bolting, good heat resistance, yield is 13% higher than that of "Jinnan Shiqin" cultivated in production.)

[0040] Hybrid seed production is divided into two parts: parental seed production and hybrid seed production:

[0041] 1. Parental seed production technology

[0042] (1) Reproduction of female parent Huang 9816

[0043] The adult plant seed collection method must be used for seed collection, and the parents must be strictly selected and eliminated. During natural pollination and seed collection, there must not be other celery varieties within 2000 meters of the female parent's breeding area.

[0044] (2) Breeding of male Benjin 9606 inbred line

[0045] The seed collection method of the male parent is the same as that of common celery varieties. Isolation and other requirements are the same as the mother parent.

Embodiment 3

[0053] Yellow 9701 X white 9807

[0054] ↓

[0055] Shuofeng 3 (F 1 hybrid)

[0056] (Plant height, hollow, light white petiole, crisp and tender, good quality, more resistant to bolting, better heat resistance, 18% higher yield than the same type of varieties in production.)

[0057] Hybrid seed production is divided into two parts: parental seed production and hybrid seed production:

[0058] 1. Parental seed production technology

[0059] (1) Reproduction of female parent Huang 9701

[0060] The adult plant seed collection method must be used for seed collection, and the parents must be strictly selected and eliminated. During natural pollination and seed collection, there must not be other celery varieties within 2000 meters of the female parent's breeding area.

[0061] (2) Breeding of male parent Bai 9807 inbred line

[0062] The seed collection method of the male parent is the same as that of common celery varieties. Isolation and other requirements are the same...

Abstract

The present invention relates to a production method of celery hybride seed. Said method uses xanthated celery parental material as female parent and uses celery parental material with normal green colour as male parent, and makes hybridization to produce the invented hybrid seed. Besides, said invention also provides its seedling stage purity detection method, its result is reliable, quick and accurate.

Description

technical field [0001] The invention relates to a production and purity identification method of vegetable crop hybrids. Background technique [0002] Celery has a cultivation history of more than 2,000 years in my country, and it is currently cultivated all over the country. It is one of the popular vegetables that are deeply loved by consumers in my country. Celery has a wide range of adaptability, and it can be cultivated and supplied almost all year round in combination with protected areas and different ecological conditions. However, there is a lack of systematic research and utilization of celery breeding in my country. The existing celery breeding work is mainly to use the original local varieties to purify and rejuvenate or use the offspring of natural hybrids between different celery varieties to select and breed new varieties, but these breeding research and utilization work are very limited. This is extremely disproportionate to the status of celery in the prod...
