Different maize genotypes showed different ability of emberyogenic calli establishment and plant regeneration . mol7 , ji846 , 81162 and 7922 had the most high rate of induction , ye 107 , 5416 and 444 were high , but longkang11 and dongnong46 had little rate of it ; the concentration of 2 , 4 - d had an enfluence on the mopha , growth and differentiation of calli 玉米胚性愈伤组织的发生是受遗传因素控制的，不同基因型其胚性愈伤组织发生率及植株再生能力存在显著差异，其中以81162 、吉846 、 7922 、 mo17的胚性愈伤诱导频率较高，掖107 、 5416 、 444的诱导率较低，龙抗11 、东农46最低。
