The invention discloses a method for rapid screening of saline-alkali-tolerant rice breeding materials, and relates to the field of saline-alkali rice breeding. If there is no mildew, ten varieties of seeds are selected, each of which has 10 seeds, and a total of 200 seeds are selected; Step 2: Raw material pretreatment: The selected rice seeds are rinsed with ethanol solution, and after the rinse is completed, use purified water to rinse again; Step 3: Grouping experiment: The treated rice seeds are grouped into petri dishes for selection and breeding. At the same time, data a, data b and data c are summarized and compared to establish a saline-alkali-tolerant rice screening model, and the rice starch The detected data is used as the judgment standard, so that the established salt-and-alkali-tolerant rice screening model can be revised, which is convenient to greatly improve the subsequent screening efficiency of rice seeds for salt-alkali-tolerant rice. |
