Screening Method for Transgenic Maize with Kanamycin Resistance

Objective] The paper was to establish simple and effective method to screen marker gene in maize with kanamycin resistance.Method] Using inbred line Chang 7-2 and hybrid Zhengdan 958 of maize as test materials,their seeds were soaked with different concentrations and volumes of kanamycin for 3 and 4 d,respectively,the rate of albino seedlings and average seedling height after sowing for 10 d were investigated.Result] The rate of albino seedlings not only was related to kanamycin concentration,but also ha...
