Popis: The available evidence indicates that F1 hybrid varieties of most naturally self-fertilized crops have potentially great economic value. The main deterrent to their wider use is the present high cost of seed production. This can be greatly reduced by breeding into these crops systems for controlled cross-fertilization. In those crops whose flowers lack nectaries (e.g. tomatoes and lettuce), self-incompatibility appears to offer a more efficient cross-fertilizing system than male sterility. Self-incompatibility systems are already available in species of tomatoes, lettuce and beans. The prospect of finding self-incompatibility in other species closely related to the remaining self-fertilized crops appears to be good. Besides introducing self-incompatibility into self-fertilized crops, the breeder also needs to introduce an efficient system of pollen transfer between plants.
