Abstract
The phenomenon of heterosis in cereal crops is expressed mainly in the first hybrid generation (F1). In order to utilize rice hybrids in commercial production, it is first necessary to produce a large amount of F1 hybrid seeds. However, rice is a strictly self-pollinated crop with tiny florets, so that it is impossible to produce bulk quantities of F1 hybrid seeds by hand emasculation. This is the primary reason why heterosis in rice has not been utilized in commercial production. To solve this problem, the most effective way, as proved by other self-pollinated crops, is to exploit the phenomenon of cytoplasmic male sterility.
