"Like begets like”. This well-known phrase which aroused so much comment among students in genetics and animal breeding has almost unconsciously become an adage to a part of their philosophy. Whatever truth or lack of it is associated with these words we admire the keenness of observation of him who wrote them. However significant the words "like begets like" could it be strictly adhered to our problem in breeding a cross-fertilized population would be greatly lessened. Much has been done in plant and animal breeding and the methods employed in accomplishing the greater part is without written history. Here and there, however, the gaps have been scaled in by written records, through the millennium of time. Though plant breeding through natural selections has been in progress, since the beginning of organic life on this earth, the application of scientific principles for plant improvement is but in its embryonic stage, and merely touched upon by man.
