Only By Ceaseless Progeny Tests Is True 
^^Bud Selection” Possible 
Years of ceaseless testing and recording went on before the discovery 
became commercially practical. This entailed intensive study and research 
of thousands of trees, of branches, and even of tiny twigs, for the selection 
of the buds which appeared to have the desired performance characteristics 
—buds from that tiny living cell which was the source of the true and con¬ 
sistent growth and bearing performance we were seeking! 
This meant that every one of the thousands of buds had >.o prove itself, 
or after perhaps several years of study, be discarded. But those surviving 
these merciless tests possessed the qualities which we were hunting for. A 
progeny tree had to prove itself more than true to name, but also true to

Drain, Massachusetts State College, inspecting an orchard 
ideal characteristics in its growth, disease resistance, the size and quality 
of the fruit it bore. 
Thus it is that today every one of the Greening’s trees offered in this 
catalog is a tree of "Registered Pedigree”—whose growth and crop per¬ 
formance are the nearest it is possible to come to ideal, and whose controlled 
characteristics give the orchardist KNOWN desirable qualities before he 
plants. 
No wonder, then, that “Bud Selection” has been given the support of 
leading scientists in the field, the wholehearted cooperation of leading 
orchardists everywhere, and has come to be recognized and accepted as 
great a contribution to the science of pomology as any development in any 
science today! 
HUNDREDS OF LEADING ORCHARDS UNDER 
OBSERVATION 
Every Owner Glad to Cooperate in This Merciless Search for Greater 
Quality and Productivity 
Every year, through hundreds of leading orchards, whose owners gladly cooperate 
with him, there walks a man—notebook in hand—searching eagerly for outstanding 
perfection in fruit. 
This man is Roy E. Gibson, director of Greening Research Department, who, under 
the direction of Chas. E. Greening, perfected the principles of Greening “Bud Selec¬ 
tion.” To quote from a letter received from Mr. Stanley Johnson, Superintendent of 
the Michigan State Experiment Station, South Haven, Michigan, “Mr. Gibson is, I 
believe, the keenest orchard observer I have ever met.” 
It is Mr. Gibson’s duty to select from trees, buds for the propagation of Greening 
“Bud Selected” fruit trees. When in his search Mr. Gibson finds a tree, sport, branch 
or limb on which fruit of evident perfection grows, careful records start. 
Each tree, or branch is given a number, painted on the trunk. A record is kept for a 
number of years before any propagating buds are taken. This complete record is kept 
on file in the Greening Record Library, a record available for inspection to our offices. 
State Horticultural Colleges and Experiment Stations, leading pomologists, horti¬ 
cultural societies and fruit growers everywhere are giving Greening their whole¬ 
hearted cooperation and support in this important work of orchard improvement. 
To list just a few among those whose names will be familiar to every one, there are 
Dr. V. R. Gardner and Prof. C. P. Halligan, of the Michigan State College; A. D. 
Shamel, Physiologist U. S. Department of Agriculture, Riverside, California,- H. P. 
Gould and L. B. Scott, Pomologists Bureau of Plant Industry, Washington, D. C.; 
Geo. M. Darrow, Bureau of Plant Breeding, Washington, D. C.,- Stanley Johnson, 
Superintendent Michigan Experiment Station, South Haven, Michigan. 
A GREAT STEP FORWARD IN FRUIT TREE PROPAGATION 
Greening “Bud Selection” therefore resolves itself to a scientific principle 
of fruit tree propagation, practiced by Greening for the sole purpose of 
making more money for the fruit grower. 
Greening “Bud Selection” is dedicated to the purpose of locating, 
segregating and separating buds and scions of desirable and unmixed 
variety as to color, size, uniform shape and early and consistent productive 
ability—and to propagate trees only from those buds and scions that have 
these essential qualities. 
Undesirable characteristics that heretofore have been explained with 
some such remark as “those things just happen” are quickly understood, once 
the scientific principles of Greening “Bud Selection” are understood. 
When they are understood they can be eliminated and are being eliminated 
constantly, in propagating Greening “Bud Selected” fruit trees. 
HOW PEDIGREED FRUIT STRAINS ARE REGISTERED 
The Greening Record Library 
All the world applauds an accomplishment that can stand as the only thing of its kind, or 
the only thing of its magnitude. And Greening’s have a notable possession that qualifies 
under this distinction. They call it their “Million Dollar Library.” (Fact is, it is while not 
actually) a million dollar possession, or one measured by any definite sum of money, is indeed 
PRICELESS ! 
It is the secret of Greening “BUD SELECTION”—the exclusive key that unlocks the vast 
store of Greening s accumulated experience. No one else has it or can have it. It goes far 
back into the years. 
It is a record of things forever beyond retrieval. That is why no one can duplicate its 
decisive and unimpeachable data. 
On the pages of these books are detailed records of the performance of thousands of 
trees—the dates they were planted, when they began to bear, how much, what kind of 
fruit they bore each year the quality, color, size, shape and every other characteristic having 
to do with profitable yield. 
These books record the history of Greening parent trees and provide the register from 
whence Greening trees are given the certification of “REGISTERED, PEDIGREED STOCK.” 
Without these permanent records, “BUD SELECTION” would be a farce. Superficial 
BUD SELECTION as a mere advertising claim, cannot succeed in producing successful 
fruit trees in the long run. Greening’s genuine “BUD SELECTION” can only be equalled by 
the same long period of time and study and by the application of the same high skill and 
horticultural knowledge as exercised in the long, keen observation and time that has been 
invested by Greening. 
In books like this, performance records of thousands of 
trees are kept in the Greening "Million Dollar Library"
