"Sex is not a necessary attribute of all living things.. [it is] a most necessary attribute if progress in evolution of new forms is to occur, as they have progressed through the ages and as we now see them progressing on this planet."

"Power to vary in plants or animals is itself a feature as readily transmissible as is stability of character. The quality of varying to meet varying environments is therefore one of the hereditary traits which the plant breeder must consider, and which may itself be extended or overcome by the processes of crossing and selection."

"Those who are making history seldom have time to record it."

"A knowledge of Mendelism is recognized by me as only the ABC to the broader knowledge of heredity necessary for success in animal and plant improvement, and all variations and all mutations of every nature are responses to environment which, by repetition and combination, are slowly but surely fixed in heredity and at last made tangible, most often through the crossing of varieties, species, or genera, either by nature or that part of nature called man."

"The essential basis of life itself, namely, , is a substance composed largely of water and having the physical constitution of a viscid liquid."

"The richest soil that was ever prepared would not grow a single blade of grass or the tiniest Weed if that soil were absolutely dry. ...There must be water in the soil to dissolve out and transfer its elements in order that the rootlets of the plant shall be able to make the slightest use of these elements. ...But ...a plant may grow and thrive for a time quite without the presence of soil if its roots are placed in water. ... some of the richest soils in the world are those that are absolutely barren and fully merit the designation of desert lands because water is lacking"

"In manufacturing food for its own cells, the plant is producing a supply of food that will be available for the sustenance of animal cells also. Thus the entire animal World may be said to be a vast parasitic colony as absolutely dependent upon the vegetable colony for its essential food supplies as any other parasite is dependent upon its host."

"When the wise plant developer goes into his garden or orchard... his eyes turn always first and foremost to the leaves..."

"He introduced almost every "new" trait by directed immigration—that is, by importing favorable features from other lineages through hybridization."

"The most interesting thing in the world, from the standpoint of animal economy—which of course includes human economy—is the wonderful laboratory or factory of the plant..."

"As a young man he developed the Burbank potato in his native Massachusetts and used the proceeds to bankroll his larger, lifetime operation in California."

"Nature has time without limit, but man has immediate need for better and still better food, houses and clothing, and our present state of civilization depends largely upon the improvements of plants and animals which have consciously and half-consciously been made by man, and future civilization must more and more depend upon scientific efforts to this end."
