Embodiment 1
[0032] Seed Production of Hybrid Pepper Yuehong 1
[0033] On September 20, 2009, the male parent (No. W405, sold by the Vegetable Research Institute of Guangdong Academy of Agricultural Sciences) was sown in Sanya, Hainan, and planted on October 15; the female parent (No. 1780, sold by Guangdong Academy of Agricultural Sciences Vegetable Institute for sale), October 22 colonization in the open field. On December 1st, according to the strict inspection of the plant morphology and flower bud characteristics of the father and mother, the miscellaneous plants were pulled out, and the miscellaneous plants were removed again on December 15th; hybrid pollination began on December 15th.
[0034] Specifically include the following steps:
[0035] (1) Picking the male parent anthers: pick off the large flower buds that are about to open after the petals turn white, take out the anthers with tweezers, then put the anthers in a container and dry them for 2-12 hours in an airtight contai...
Embodiment 2
[0046] Seed Production of Hybrid Pepper Huifeng 2
[0047] On February 10, 2010, the male parent (No. W2102, sold by the Vegetable Research Institute of Guangdong Academy of Agricultural Sciences) was sown in Xinzhou, Shanxi, and planted on May 15; the female parent (No. W2280, sold by Guangdong Academy of Agricultural Sciences Vegetable Institute for sale), and planted in plastic greenhouses on May 15. On June 8th, according to the strict inspection of the plant morphology and flower bud characteristics of the father and mother, the miscellaneous plants were pulled out, and the miscellaneous plants were removed again on June 14; hybrid pollination began on June 15th.
[0048] The specific operation steps are the same as the steps (1)-(4) of Example 1.
[0049] The female parent F was harvested on September 30, 2010 1 On average, 33 kg of hybrid pepper Huifeng No. 2 seeds were obtained per acre.

Abstract
The invention discloses a seed production method for a hybrid pepper variety. The seed production method comprises the following steps of: manually removing an anther of a pepper female parent, collecting pollen of a peeper male parent, and carrying out artificial supplementary pollination on the pepper female parent, wherein the produced F1 generation seed is a hybrid seed; the step of manually removing the anther of the pepper female parent is carried out through adopting a manual rotation method; the manual rotation method comprises the following steps: a joint position between a pedicel and a receptacle is pinched by a left hand; a position, where is close to the receptacle, of a corolla is gently pinched by a thumb and a forefinger of a right hand; and the thumb and the forefinger slowly twist, so that the corolla and the anther are removed, and a style and an ovary are exposed. A female parent emasculation method (manual rotation method) disclosed by the invention has the characteristics of saving labor and force, capably reducing production cost, realizing thorough emasculation, and capably ensuring emasculation quality; and a stamp-pad ink marking method is adopted by the invention, and the stamp-pad ink cost is low, so that the production cost can be reduced, as well as labor and force are saved. The conventional marking method is an iron ring marking method; the ironring marking method is realized through bonding an iron ring on a pollinated stalk, so that the operation cost is high; and the iron ring has a certain weight, so that flowers are easy to fall off, therefore the yield is low.
Description
technical field [0001] The invention belongs to the technical field of crop seed production, and in particular relates to a method for producing hybrid pepper varieties. Background technique [0002] Pepper is one of the most important vegetable crops in the world. It has a wide range of uses. It can be eaten fresh and an important seasoning. It has become an indispensable food in people's daily life. [0003] my country has a long history of pepper cultivation, abundant germplasm resources, and the planting area ranks first in the world, with an annual planting area of more than 1.3 million ha 2 , plays an important role in ensuring the annual balanced supply of vegetables in our country. [0004] The heterosis of pepper is obvious, and the hybrid varieties have been widely used in production. Since the 1980s, my country has successively bred a large number of high-quality, high-yield, and disease-resistant hybrid varieties, forming varieties such as Zhongjiao series, X...
