to Virus Infection! 
Greening Bud Selection methods eliminate virus 
diseases. This fact alone is worth the entire effort that 
has gone into creating Greening Super-Selected Fruit 
Trees. 
Virus disease may be transmitted from one tree 
to another by grafting and budding. It is oftentimes 
present in the original nursery stock. It is absent in 
all Greening Super-Selected Trees. 
Buds for Greening Super-Selected Trees are taken 
only from parent trees with a virus-free record. The 
Sun-Glo Peach parent tree, illustrated and described on 
page 24, from which buds for the propagation of this 
variety are taken, has a virus-free record of 12 years.

“In 1922, the Horticultural Section of the Mich¬ 
igan Station began a study of this question, limited to 
field observations at first, then expanded to include 
propagation tests and laboratory studies. In assem¬ 
bling its present collection of over 400 ‘Selections’ the 
Station has had the cooperation of the Greening Nur¬ 
sery Company, of Monroe, Michigan, which had be¬ 
gun such a collection in 1910. Especially valuable has 
been the assistance of Mr. Roy Gibson, of the same 
firm, whose field observations, yield records, and other 
records of individual trees and limbs in hundreds of 
Michigan orchards extend back to 1917.”

“This is to certify that Roy E. Gibson, with the 
Research Department of The Greening Nursery Co., 
Monroe, Michigan, kept bud selection records in our 
orchard of the South Haven peach variety beginning 
in 1920, and in 1923 cut propagating buds from Tree 
No. 20. This tree is the equal in every way of the 
original South Haven tree that was on our farm. Tree 
No. 20 was free from every symptom of Red Suture 
or other virus diseases in the seasons of 1923, 1924, 
1925, 1926, 1927, 1928, 1929 and 1930, which condi¬ 
tion was checked by Mr. Gibson and myself person¬ 
ally.”

Read What Mr. Barden, Another 
Prominent Grower, of South 
Haven, Michigan, Says 
“This is to certify that Roy E. Gibson, with The 
Greening Nursery Co., Monroe, Michigan, has made 
observations and kept bud selection records in a num¬ 
ber of varieties of peaches in our orchards. In 1926 he 
cut propagation buds from tree marked No. 2, which 
is an ideal type of Elberta and was free from symp¬ 
toms of Red Suture and other virus diseases in the 
seasons of 1926, 1927, 1928, 1929 and 1930.”
