Abstract

Rhizome propagation would be a most useful method for breeding perennial rice genotypes. Some of the wild species-Oryza longistaminata, O. officinalis, O. rhizomatis, and O. australiensis-are logical sources of perenniality. Among them, only O. longistaminata has an AA genome like O. sativa. When RD23, an indica cultivar from Thailand, was pollinated by O. longistaminata, one hybrid plant was obtained through embryo rescue. The interspecific hybrid had strong rhizome expression and showed 32.53% pollen fertility. When the hybrid was pollinated by RD23, 162 BC1F1 plants were obtained, among which only one individual had rhizomes like the F1 hybrid.
