37 soybean variety drought resistance screening abstract: Selects 37 Beijing for to try the material to use high infiltrates the solution polyethylene glycol (PEG6000) simulation arid environment, the determination exsomatize leaf blade retention ability and the chlorophyll content, big awning arid coercion direct division drought-resistant rank method screening is suitable for the Beijing area planter the drought-resistant soybean variety, selects two good materials: By measured the germination percentage, the germination tendency, the root long index, the retention ability, the chlorophyll content and the big awning arid rank method screens the drought-resistant soybean variety is KY93014-3, by measured the germination percentage, the germination tendency, the root long index screen the variety is Beijing abundant 1, provides the parent material and the scientific basis for the drought-resistant breeding.The test result indicated that,In continues under the arid environment, the drought-resistant soybean seed has the germination rate to be high, the root long index is big, the retention ability is high, chlorophyll content Gao Jigao combats drought characteristics and so on rank.Key word: Soybean; Drought resistance; Screening |
