Original seed breeding equipment based on breeding of rice thermo-sensitive dual-purpose genic male sterile line

Abstract

The invention discloses original seed breeding equipment based on breeding of a rice temperature-sensitive dual-purpose genic male sterile line, and belongs to the field of breeding. According to the original seed breeding equipment based on breeding of the rice temperature-sensitive dual-purpose genic male sterile line, by arranging a shading ring piece, light-changing cavities can be inflated and sucked, light-changing liquid is introduced, so that expansion of the shading ring piece can be controlled, and the shading ring piece can restore to the original position, switching between the created long-day high-temperature environment and the created short-day low-temperature environment is achieved, meanwhile, compared with the operation of manually shading black cloth in the prior art, the workload is remarkably reduced, the working efficiency is improved, meanwhile, the illumination adjusting effect is better, meanwhile, a shading moisture absorption chain net is arranged in a matched mode, moisture in the light-changing cavities is effectively absorbed, when a long-day high-temperature environment is built, the situation that the moisture is in a vapor shape and adheres to the inner walls of the light-changing cavities under sunlight can be effectively avoided, and it is effectively guaranteed that natural light irradiating inwards is not prone to being reflected.

Description

technical field [0001] The invention relates to the field of selective breeding, and more particularly, to an original seed breeding equipment based on the selective breeding of a rice thermosensitive dual-purpose sterility line. Background technique [0002] Hybrid rice requires two basic parents, one is the female sterile line and the other is the male parent of the restorer line. These two parents together determine the agronomic traits of the hybrid rice variety. Rice temperature (light) sensitive dual-purpose GM sterile line is the female parent of two-line hybrid rice, and it is a hybrid rice parent that is highly dependent on climatic conditions. Self-propagation, under another climatic condition (long-day high temperature), can achieve sterility, as the female parent of two-line hybrid rice. [0003] Two-line hybrid rice has developed rapidly, and the two-line sterile line has developed rapidly and has been replaced rapidly. A large number of dual-purpose sterile li...

Problems solved by technology

[0009] Aiming at the problems existing in the prior art, the object of the present invention is to provide a kind of original seed breeding equipment based on rice temperature-sensitive dual-purpose GMS line breeding, which can pass through the light-changing cavity through the setting of the light-shielding ring The air is filled with air, and the light-changing liquid is passed through, so that the expansion of the shading ring can be controlled and the original position can be restored, so as to realize the switching between the long-day high temperature and short-day low temperature environment, and compared with the existing technology The operation of manually covering and placing the black cloth can significantly reduce the workload, improve work efficiency, and at the same time make the adjustment effect on the light better. In the high temperature environment, it can effectively avoid the occurrence of moisture sticking to the inner wall of the light-changing cavity in the form of steam under the sun, and effectively ensure that the natural light irradiated inward is not easy to be reflected
