✦ Synopsis
The available evidence indicates that F 1 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 .
