The invention relates to a method for screening a drought-resistant corn
germplasm and belongs to the field of
crop genetics and breeding. The method for screening the drought-resistant corn
germplasm includes the following steps that 1,
sowing corn seeds with the corn
germplasm, 2, conducting final singling of seedlings of corn plants, 3, treating the corn plants with
drought stress, 4, detecting corn germplasm
plant morphological indexes, 5, detecting corn germplasm yield indexes, 6, evaluating the
drought resistance ability of the corn germplasm and 7, selecting the corn germplasm with the
drought resistance. The method for screening the drought-resistant corn germplasm uses the corn germplasm as a detection object, the
drought stress treatment is conducted in the whole growth period, by detecting the
plant morphological indexes and the yield indexes, the purpose of building an objective and accurate method for screening the drought-resistant corn germplasm is achieved, and therefore a reliable basis is provided for drought-resistant corn germplasm screening.
