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 />
