摘要
The wide compatibility gene contained in Paddy may be transferred into the varieties of japonica, javanica or indica type. Also, it may be recombined with restoring gene for the sterile lines of BT type or WA type,This makes it possible to utilize heterosis between subspecies by using the thiee-line method.In addition, it may be recombined with the photoperiod sensitive sterile gene within nucleus so as to develop the best genetic tool for utilization of heterosis between subspecies indica and japonica─a wide compatibility-photopeniod sensitive genic sterile Line with japonica cytoplasm and indica nucleus. It can also be combined with dwarf gene, which helps to solve the problem that the subspecies hybrids express heterobeltiosis in plant height.
