玉米植株的再生在1975年从品系 A188 和由该品系组配的杂交种的未成熟胚的圆锥形愈伤组织中首次获得成功(Green 等,1975)。在玉米组织培养中形成8种愈伤组织:形态发生型、胚胎发生型和无再生潜力型。通过异源愈伤组织中幼芽的形态发生可以获得数量有限的常常具有遗传学和细胞学多样性的植株。作物的形态发生潜力在很大程度上取决于基因型。玉米体细胞胚胎发生现象在1982年就曾有人描述过(Ly 等,1982)。从旺盛生长着的大量体细胞胚胎中获得的众多再生植株可以用于突变发生试验、繁殖有价值的基因型和遗传工
The regeneration of maize plants was first successful in 1975 from conical callus of line A188 and immature embryos of hybrids that were assembled from the line (Green et al., 1975). Eight types of callus were formed in maize tissue culture: morphogenesis, embryogenesis and non-regeneration potential. A limited number of plants, often genetically and cytologically diverse, can be obtained by the shoot morphogenesis in heterologous callus. The morphogenesis potential of crops depends very much on the genotype. Maize somatic embryogenesis was described in 1982 (Ly et al., 1982). Numerous regenerated plants derived from a large number of somatic embryos that are flourishing can be used for mutation testing, breeding of valuable genotypes and genetic work
