Abstract
Different crossing techniques,emasculation and pollination procedures for obtaining young embryos from hybrid of Oryza minuta and Oryza sativa have been evaluated,and the effects of different sterilization methods(20% NaClO or 0.1% HgCl2),inoculation materials,culture media and the age of embryos on the germination rate of young embryo has been investigated by using four cultivated rice(Oryza sativa,2n=24,AA) and two wild specie(Oryza minuta,2n=48,BBCC).The results showed that the production of young embryo from hybrids was higher when cultivated rice was used as female and wild species as male parent.Emasculation with artificial spikelet-cut and continuous pollination for 3 days resulted in to higher rates of embryo development.During the process of embryo rescue,applying young embryo after pollinating of 10-12 days and sterilizing with 0.1% HgCl2 for 10 minutes followed by culture inoculation with ovary-slice to 1 / 4 MS medium resulted in the higher germination rate of young embryo,and the hybrid plant were obtained.These methods are simple,convenient and economically feasible,therefore,may be utilized in crossing of cultivated rice and wild species without AA genome.
