This study USES indoor cultivation and potted trial, with seven backbone maize for material, high salt (NaCl) and water treatment, two different maize under salt stress in the seed germination and seedling morphological changes. Results show that the stress of maize seed germination and seedling morphological and different degree of adverse effects of different maize resistant to salt exists obvious differences between genotype. 5 inbred lines of seed germination salt resistance from high to low for "330", "E28", "Mo17", "huang zong 31" and "C". Overall, the morphological characters of different inbred lines with the same inbred lines of different morphological characters of resistance to salt stress index. Comprehensive analysis of the five key under salt stress on the characteristics of morphology, inbred lines H92 ", "the strongest maize resistant to salt, as to choose" genotypes, K184 "and" above the salt resistant 31 ", and "low" and the "yellow C 3.3 high salt to the most sensitive. In addition, the corn varieties resistant to salt stress of genetic improvement is possible.

This research uses in the room the raise and the pot experiment, take 7 backbone corn inbred line department as the material, establishes high salty (NaCl) and the running water two kind of processing, the research different corn inbred line is under the salty coercion seed germination and the seedling adult plant shape change.The result indicated that, the salty coercion to the corn inbred line is the seed germination and the seedling adult plant shape degree different adverse effect, different corn inbred line department's salt endurance existence obvious genotype difference.5 inbred lines are the salt endurance which the seed sprouts from high to low in turn are 330,E28,Mo17,the synthesis 31 and yellow C. Overall, the different inbred line department's identical shape character and the identical inbred line department's different shape character bears the salty coercion index existence difference.Generalized analysis salt coercion next 5 big backbone inbred line department's shape characteristic, by H92 the salt endurance strongest corn inbred line department, may take bears the salty genotype to choose,K184 and synthesis 31 the salt endurance is low, but 330 and yellow C is most sensitive to Gao Yan.In addition, carries on to the corn variety bears the salty coercion the heredity improvement is feasible.
