Bumble bee pollination seed production method of hot pepper cytoplasmic male sterile line

Abstract

The invention provides a bumble bee pollination seed production method of hot pepper cytoplasmic male sterile line, comprising the steps of raising seedling; preparing soil and paving mulching films; building a net room or shed room; transplanting male parents and female parents to the net room or shed room; putting the bumble bees to the net room or shed room at this time; regulating flower quantity, because the bumble bees are used for pollinating, the male parents produce lots of fruits, the development speed of the fruits is accelerated and then the pollen for the male parents is supplied insufficiently, thus removing the fruits of the male parents in time so as to increase flower quantity of the male parents. The method replaces the artificial pollination with the bumble bee pollination, so that the method solves the contradict between labor intensity and insufficient labor during the seed production of hot pepper male sterile, simplifies pollination process, achieves annual seed production scale of the seed production in the net room, the shed and sunlight greenhouse, enables the hot pepper male sterile seed production to be in large scale production and annual, and has a profound significance in research and development of the seed production technology of the hot pepper cytoplasmic male sterile line in our country.

Description

technical field [0001] The invention belongs to the technical field of male sterile line pollination and seed production, and in particular relates to a method for pollination and seed production of capsicum cytoplasmic male sterile line bumblebee Background technique [0002] Artificial pollination is a key link in the production of pepper cytoplasmic male sterile lines. It usually goes through the following steps: deflowering-stripping pollen-drying pollen-sieving-artificial pollination. This method has complicated procedures, labor-intensive, and high production costs; The influence of human factors is relatively large, especially in recent years, the serious shortage of labor force makes artificial pollination a restrictive factor in the production of pepper male sterile lines. At present, the seed production of pepper male sterile lines in my country mostly adopts net room breeding. Due to the limitation of climatic factors, the seed production scale is small and the de...

[0002] Artificial pollination is a key link in the production of pepper cytoplasmic male sterile lines. It usually goes through the following steps: deflowering-stripping pollen-drying pollen-sieving-artificial pollination. This method has complicated procedures, labor-intensive, and high production costs; The influence of human factors is relatively large, especially in recent years, the labor force is seriously scarce, making artificial pollination a restrictive factor in the production of pepper male sterile lines

At present, the seed production method of pepper male sterile lines in my country mostly adopts net room breeding. Due to the limitation of climatic factors, the seed production scale is small and the development speed is slow, which seriously affects the research and development of pepper male sterile seed production technology in my country.
