An original seed breeding equipment based on the selection and breeding of rice temperature-sensitive dual-purpose genetic male sterile lines

Abstract

The invention discloses an original seed breeding equipment based on the selection and breeding of a temperature-sensitive dual-purpose nuclear sterile line of rice, belonging to the field of selection and breeding, and an original seed breeding equipment based on the selection and breeding of a temperature-sensitive dual-purpose nuclear sterile line of rice The device, through the setting of the shading ring, can inhale air into the light-changing cavity and pass in the light-changing liquid, so as to control the expansion of the light-shading ring and return to its original position, so as to realize the long-term high temperature and high temperature of the building. The short-day low-temperature environment switching, and compared with the manual operation of manually covering the black cloth in the prior art, significantly reduces the workload and improves work efficiency. It can effectively absorb the moisture in the light-changing cavity. When creating a long-day high-temperature environment, it can effectively prevent the moisture from sticking to the inner wall of the light-changing cavity in the form of steam under sunlight, and effectively ensure that the natural light irradiated inward is not easy to be absorbed. reflection.

Description

technical field [0001] The invention relates to the field of breeding and breeding, more specifically, relates to an original seed breeding equipment based on the breeding of thermosensitive dual-purpose nuclear sterile lines of rice. Background technique [0002] Hybrid rice requires two basic parents, one is the female parent of the sterile line and the other is the male parent of the restorer line. These two parents jointly determine the agronomic characteristics of the hybrid rice variety. The temperature (light) sensitive dual-purpose GMS line of rice is the female parent of two-line hybrid rice. It is a female parent of hybrid rice that is highly dependent on climatic conditions. Under a certain climatic condition (short day and low temperature), it can achieve Self-propagation, under another certain climatic conditions (long-day high temperature), can achieve sterility, as the female parent of two-line hybrid rice. [0003] The rapid development of two-line hybrid ri...

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
