Presentation of Award<br />

J. Roy Q u i n b y w a s p r e s e n t e d w i t h a marble mosaic plaque w i t h the following inscription:<br />

In recognition of 57 years contribution to our knowledge of sorghum by the delegates of the<br />

Sorghum in the Eighties Symposium, Hyderabad, India.<br />

November 2 - 7 . 1981"<br />

J . Roy Quinby w a s e m p l o y e d t o w o r k o n s o r g h u m<br />

at t h e Chillicothe Station at Texas A & M University<br />

in 1924, 57 years ago. O n e of his earliest<br />

publications appeared in 1 9 3 1 . He b e c a m e superintendent<br />

of t h e station in 1925 and at that t i m e<br />

his lifelong associate, J. C. Stephens w a s also<br />

e m p l o y e d there.<br />

M r . Q u i n b y has pioneered our k n o w l e d g e of t h e<br />

inheritance of maturity in s o r g h u m w i t h the first<br />

publication appearing in 1945. He also undertook<br />

t h e study of t h e genetic control of plant height and<br />

published in 1954. The understanding of t h e<br />

inheritance of t h e s e t w o traits has been f u n ­<br />

d a m e n t a l to all s o r g h u m scientists w o r k i n g to<br />

adapt s o r g h u m to n e w areas or n e w situations<br />

leading to i m p r o v e d production.<br />

M r . Q u i n b y has had a long interest in t h e<br />

c o m m e r c i a l use of hybrids including t h e use of<br />

m a l e sterility to facilitate s e e d production.<br />

There are major papers concerning hybrid vigor<br />

that w e r e published by Karper and Quinby in<br />

1937, and by Stephens and Quinby in 1952.<br />

Results s h o w i n g substantial increases in yield d u e<br />

to hybrid vigor w e r e p r e s e n t e d in t h e s e papers. I<br />

w o u l d like t o read f r o m Mr. Q u i n b y ' s o w n w r i t i n g<br />

in a TAES publication "A T r i u m p h of Research....Sorghum<br />

in T e x a s . " "Dr. R. D. L e w i s c a m e<br />

to Texas in 1946 to be Director of the Texas<br />

Agricultural E x p e r i m e n t Station. W h i l e h e w a s<br />

visiting at t h e Chillicothe Station I s h o w e d Dr.<br />

L e w i s a m a n u s c r i p t that contained a picture w i t h<br />

t h e caption The use of hybrid vigor in s o r g h u m<br />

a w a i t s t h e solution of p r o b l e m s in t h e economical<br />

production of hybrid s e e d .<br />

" B e f o r e Dr. L e w i s left t h e Chillicothe Station<br />

that day he told Stephens and me that he w o u l d<br />

approve a proposal for research on m e t h o d s of<br />

producing hybrid s o r g h u m s e e d i f w e w o u l d<br />

prepare s u c h a proposal." Roy Quinby and his<br />

associates undertook to i m p l e m e n t Hatch Project<br />

6 1 0 dated 4 October 1947. The objective of this<br />

project w a s to produce seed of s o r g h u m hybrids<br />

in commercially useful a m o u n t s .<br />

In 1948 Stephens felt that he had identified<br />

cytoplasmic male-sterility. Again quoting Mr.<br />

Quinby, "Early one morning in 1952 Stephens and<br />

I decided that cytoplasmic male-sterility looked<br />

t o o g o o d t o abandon" and w o r k o n other m e c h a n ­<br />

isms of male-sterility w e r e terminated. By 1955,<br />

seven hybrids w e r e considered to be useful for<br />

farmer production. Mr. Quinby and J.C. Stephens<br />

shared the Hoblitzelle A w a r d for The A d v a n c e ­<br />

m e n t of Texas Rural Life.<br />

Events m o v e d rapidly; by 1957 there w a s<br />

sufficient hybrid seed t o s o w 1 5 % o f t h e s o r g h u m<br />

acreage in the USA and by 1960 s o m e 9 5 % w a s<br />

s o w n . Hybrids combined w i t h irrigation and increased<br />

use of fertilizer increased s o r g h u m production<br />

in the USA threefold w i t h little increase in<br />

acreage.<br />

Mr. Quinby joined the Pioneer Seed C o m p a n y<br />

in 1961 after retiring f r o m the Texas A & M<br />

University. Quinby m a d e the first cross to start a<br />

c o n v e r s i o n program in January 1962. J. C.<br />

Stephens prepared a proposal to undertake a<br />

tropical conversion program using facilities of t h e<br />

U.S. Department of Agriculture in Puerto Rico in<br />

t h e tropics and those of the Texas Agricultural<br />

Experiment Station, at Chillicothe, in t h e t e m p e r ­<br />

ate zone. The proposal w a s approved by t h e<br />

Texas Station and U.S. D e p a r t m e n t of Agriculture<br />

in June 1963 and w o r k began at Mayaguez,<br />

Puerto Rico, in the fall of that year. All s o r g h u m<br />

scientists are aware of this conversion program<br />

and m o s t of t h e m are using converted lines in<br />

their breeding programs. This program has b e e n<br />

invaluable as a source of resistance traits and has<br />

contributed to yield i m p r o v e m e n t in m a n y places<br />

in t h e w o r l d .<br />

Today, Roy Quinby is actively involved in t h e<br />
