Embodiment 1

[0022] This example is T5 sweet pepper seed production. Taking Zhenjiang Ruifan Agronomy Co., Ltd. as an example to independently breed T5 sweet pepper, the parents are separated and screened T5F as the male parent and T5M as the female parent, both of which are small fruit-shaped sweet peppers , to grow seedlings around the Spring Festival, the seedling period is 3 months for colonization, and seed production begins in May. Seed production steps are as follows:

[0023] (1) Collect all the flowers from the male parent that are in full bloom and not loose powder to the stage of full bloom and loose powder, put them into a sulfuric acid paper bag, place them on an electric blanket to dry until the pollen is scattered, and then pass through a sieve, sieve the pollen, and then mix it with the pollen Add white flour and mix well, the ratio is 1:3.

[0024] (2) Peel the buds and detassele with bare hands, wait for the flowers of the female Honda Simendou to bloom, remove all the f...

Embodiment 2

[0030] This example is Z3 thin-skinned pepper seed production. Taking Z3 thin-skinned pepper independently selected by Zhenjiang Ruifan Agronomy Co., Ltd. as an example, the parent is the Z3F male parent and T6M as the female parent, and the male parent is a small fruit-shaped pepper. This is a small fruit-shaped sweet pepper. The seedlings are raised around the Spring Festival. The seedlings are planted in 3 months, and the seed production begins in May. Proceed as follows:

[0031] (1) Collect all the flowers from the male parent that are in full bloom and not loose powder to the stage of full bloom and loose powder, put them into a sulfuric acid paper bag, place them on an electric blanket to dry until the pollen is scattered, and then pass through a sieve, sieve the pollen, and then mix it with the pollen Add white flour and mix well, the ratio is 1:3.

[0032] (2) Peel the buds and detassele with bare hands. After the flowers of the female Honda Simendou are in full bloo...

Abstract

The invention discloses a large-field pepper hybrid seed production method and belongs to the technical field of plant hybrid seed production. The large-field pepper hybrid seed production method is used for overcoming conditions of great labor wastes, low seed production and plenty hybrid seeds in the existing large-field pepper hybrid seed production process. The large-field pepper hybrid seed production method comprises the following specific steps: (1) collecting and treating pollen; (2) castrating; (3) pollinating; (4) marking labels; and (5) performing hybridization aftertreatment and harvesting. The large-field pepper hybrid seed production method has the characteristics of low pollen consumption, convenient castration, simple pollination, simple marking and convenient allocarpy confirmation during harvesting, and is capable of greatly reducing the labor consumption during the large-field pepper hybrid seed production process and improving the hybrid seed purity.

Description

technical field [0001] The invention relates to a plant hybrid seed production method, in particular to a field capsicum hybrid seed production method, which belongs to the technical field of plant hybridization. Background technique [0002] Capsicum is a hermaphroditic crop with strong heterosis. Most of the cultivated species are hybrids, and the inbred species have self-degeneration phenomenon. Capsicum is the second largest vegetable crop in my country, and its planting area is second only to Chinese cabbage. At present, in the process of pepper seed production, a small amount of male sterile line seed production is carried out for three lines. In addition, conventional emasculation and hybrid seed production are carried out. The demand for seeds is huge. At this stage, the cost of seed production for one mu of pepper seed production The increase from 8,000 yuan in previous years to 24,000 yuan is enough to prove the manpower and material resources consumed in the proce...
