Abstract: This paper deals with systematic studies on the protoplast culture of multitiller and multispike forage maize, including selection of genotypes, induction and subculture of embryogenic calli, cell suspansion culture and protoplast culture. Methods such as liquid culture, nurse culture and agarose bead culture were used for protoplast culture. Four cell clones were obtained. Of which calli and embryoids derived from protoplasts were induced from 79, 55 and 79-8 three genotypes, and regenerated plants were acquired from 79 and 79-8. One of the regenerated plants, after being transplanted into soil, developed normally with flowering and earing. After self and cross pollinations three ears with normally developed seeds were obtained. These seeds germinated well in germination test.

Key words: Forage maize, Protoplast culture, Flowering and seeding of regenerated Plant
