Evaluation of sterile of appraisal-sensitive genie male-sterile in paddy and study on water temperature procession system for breeding

The sterile sensitive phase of the Appraisal-sensitive Genie Male-sterile in paddy shows sterile and it can breed hybridized seed with male parent when they stay in a certain temperature. However, in anther temperature conditions, they show male sterile and they breed seed with themselves. The conversion temperature that from sterile to male sterile decide the two-line hybrid rice breed seed hazard, so the technology crux of breed seed is how to decide the conversion temperature and screens the photoperiod-sensitive genie mail-sterile rice that leads to the temperature lower. In this paper, we use the air conditioner to cooling and heating. The temperature is automatic-controlled from 17℃ to 30℃ by temperature-controll instrument. The water in temperature controlled pool and the procession pool is continuous circulation in order to ensure the water temperature constant and stay in necessary range and meet with the evaluation the male-sterile of photoperiod-sensitive genie male-sterile rice and fast the breeding seed. It provides an economical and adaptation equipment for breeding hybridized seeds, and contracts with man-climate, it has quite less cost, the characterical is fairly static. and can quite good simulate the natural circumastion. Especially using the cool water in breeding seed. The real application proves that the systematic performance is reliable, less investment and consumer and the result is very good.
