Abstract
Cell fusion was used to obtain hybrid plants of rice (Oryza sativa L.) and four wild Oryza species, O. officinalis, O. eichingeri, O. brachyantha, and O. perrieri, to incorporate useful traits of the latter species into rice. A total of 250 mature hybrid plants were obtained by electrofusion and nurse culture methods. The hybrid nature of these plants was confirmed by karyotypic, morphological, and isozyme analysis. The hybrids of O. sativa+O. eichingeri, O. sativa+O. officinalis and O. sativa+O. perrieri produced viable pollen and the O. sativa+O. eichingeri hybrid has produced a progeny plant. Our study demonstrates the use of cell fusion for future rice improvement.
