In Vitro Fertilization in Maizeough protoplast fusion, the intraovarian pollination and in vitro fertilization techniques can be made use of in producing crosses in which the incompatibility is due to the presence of an extra-long style and a short pollen tube. The technique of test-tube pollination/fertilization involves in grow

Embryogenesis in Haploid Cell Culture of Maize the pure line can quickly be selected from the inbred line derived from the haploid, much attention has been paid to some inbred lines induced by parthenogenesis and anther culture (Chase 1974; Genovesi and Collins 1982; Wu et al. 1983; Petolino and Jones 1986; Genovesi 1990). However, these two me

Isolated Microspore Culture of Maizetic embryos is lacking for most regeneration systems (Fransz and Schel 1991); therefore, totipotent microspores offer a potentially useful subject for both basic and applied studies. Although anther culture can be an efficient method of producing doubled haploid lines for breeding applications, cult

Transformation of Maize Protoplastsplasts (Davey et al. 1980; Krens et al. 1982). Soon after, however, research activities were directed toward the genetic transformation of plant cells, rather than protoplasts, using . as a natural DNA transfer system (review: Hooykaas 1989). The genetic transformation of dicotyledonous plants was a
