Sinossi
Excerpt from Seed Breeding
The law of inertia, which is defined as being that condition of matter by which its existing state is retained, if at rest, rest; if in motion, the continuance of that motion until other forces in action shall produce a change, serves as well for the consideration of the problem of life. A perfect likeness be tween parent and offspring would presuppose the parents being from all time in a state of inertia, a supposition which nullifies the proposition, as the act of having offspring would be a departure from that state. Yet when we define the science of breeding, and state that like produces like, we recognize the fallacy of the preposition as applied with exactness to individuals, and modify it immediately by limi tations, which if they serve to weaken the statement, yet serve to make it not contradictory to our experience. Rather the law of variation should be the key-word for breeding; although the proposition that like produces like as a men tal conception is as true and as applicable as is the proposi tion that inertia is a definition of a law of nature. Like does produce like when every condition is removed which would produce difference, which only can be done as a men tal act; a body is considered as continumg in Its present state when every condition involving a change is removed by a mental act. Hence the law of likeness is of the most importance to that breeder who desires to so modify surround ings as to restrain his animals from being improved in their progeny; and the law of variation is deserving of the more attention from that breeder who would desire to improve his animals in their progeny.

Paperback. Condizione: New. Print on Demand. This book posits that farming can see great improvements through the use of scientific principles applied to the raising of livestock, the planting of crops, and particularly the breeding of grains. The author presents a clear and comprehensive theory of breeding predicated on the idea that increasing herd and crop productivity is achieved through a progressive process that can be learned and applied anywhere. Arguing that a true and comprehensive understanding of hereditary dynamics is indispensable to progress, the author maintains that this principle extends far beyond the simple principle that âlike begets like,â and must be understood in its broader context. From the breeding of better sheep to the development of better corn, this volume provides a wealth of historical examples, practical advice, and theoretical explanations for farmers who want to increase the yield and quality of their products. The author shows that it is through careful selection of the best specimens that we can overcome the tendency for species to revert to type, and ultimately arrive at plants and livestock that consistently exceed expectations. This book contains important insights and valuable information for any agriculturalist, and provides a firm foundation for understanding the discipline of breeding.
