The method for screening radish late bloting character includes the stage of vernalization and photostage, and adopts the following steps: disinfecting the seed to be identified and soaking the seed with sterile water for accelerating germination, inoculating the seed in sprouting state into MS culture medium, placing it into refrigerator, making artificial iarovization in time periods, after low-temp. treatment placing it into tissue culture chamber to make growth culture of radish seedling. In the photostage transplanting the radish seedling into the prenursery tray with matrix and placing it into tissue culture chamber and observing the bolting condition of squaring period by using different materials and making different treatments to identify the bloting characters of different materials, so that it can accelerate radish late bloting breeding process.

The invention discloses a soybean salt tolerance and saline-alkaline tolerance screening device and an identification method. The soybean salt tolerance and saline-alkaline tolerance screening device comprises a working frame and a solution stirring bucket; the working frame comprises an upper layer and a lower layer; the upper layer of the working frame is provided with a pass box and the lower layer is provided with a water supply tower which is used for supplying water or salt solution for the pass box; the solution stirring bucket and the water supply tower are connected through a water pipe; the water supply tower and the pass box are connected through a water pipe; a fixing net is fixedly arranged inside the pass box; a breeding pipe is arranged inside grids; the lateral wall surface and the bottom surface of the breeding pipe are provided with permeable holes; the solution permeates the breeding pipe through the permeable holes; water (or the salt solution) is automatically replaced through an electromagnet valve which is controlled by a timer. The soybean salt tolerance and saline-alkaline tolerance identification method established by utilizing the device is stable, scientific and simple and beneficial to large-scale identification and large-scale screening can be performed inside space with limited greenhouse, the degree of automation is high, the environmental influences are small, the repeatability is strong, and the screening result is reliable.
