ROBSON QUALITY SEEDS, HALL, NEW YORK 
39 

Plant breeders are developing many varieties of disease resistant vegetables but it is seldom that they are able to combine disease re- 
sistance with exceptionally high yield. 
NEW YORK CERTIFIED ONTARIO: 120 days. 
Ontario is a seedling resulting from a cross made by 
the U. S. Dept. of Agriculture. Our farms are in 
the limestone belt of New York State where the soil 
is favorable for the development of potato scab. In 
fact, we have been forced to grow our New York 
Certified seed in other areas of the State where potato 
scab is not a problem. 
Some years ago we set up a scab testing plot on 
one of our farms in cooperation .with the New York 
State College of Agriculture. Here on the same 
scab infested land year after year various new varie- 
ties of potatoes were tested for resistance to scab. 
Ontario was outstanding and also had what many 
others did not have—fair to good cooking quality and 
yield. Ontario has been tested in many other places 
and we are sure that it will do much to solve the scab 
problem in those sections that are affected. Ontario 
comes out clean where other varieties fail. 
Ontario tubers are very smooth, shallow-eyed, 
white and slightly elongated; not only very resistant 
to scab but quite resistant to late blight and “Z” 
disease. 1 peck (15 lbs.) by Parcel Post $1.95; pre- 
paid; 1 to 10 bags $5.50 per 100 lb. bag; 10 to 50 bags 
$5.35; 50 bags or more $5.25, not prepaid. 
SWEET POTATO PLANTS 
100 plants will set 150 ft. row 
Sweet potatoes can be successfully grown in the 
Northern States providing you have a sandy soil, 
plant the right variety and follow our cultural direc- 
tions. If you have the soil we will supply you with 
the plants and full cultural directions. 
Our Northern growers are finding that sweet pota- 
toes can be grown farther North than was thought pos- 
sible. This is the result of new and earlier varieties 
and better cultural practices. A new variety devel- 
oped in Maryland called “Maryland Golden’ has 
given wonderful results in New York State. We sup- 
ply each purchaser of plants with detailed instructions 
on how to grow sweet potatoes successfully. All you 
need is a moderately light, fertile soil. 
MARYLAND GOLDEN: 120 days. One of the most 
attractive and productive varieties we have ever 
seen. Flesh golden color and medium dry. Stores 
well but is tender and must be handled carefully. 
Plants ready for shipment about June Ist. 25 plants 
75c; 50 plants $1.35; 100 plants $2.20 prepaid; 500 
plants $6.00; 1000 plants $10.00 not prepaid. 
Ontario is resistant to scab and reports indicate as high as 800 bushels yield per acre. 
NEW YORK STATE CERTIFIED ESSEX: 105 
days. Vine growth and tubers much like Irish Cob- 
bler. Sets many tubers and cannot bring all of them 
up to size in a dry season. Highly resistant to late 
blight and has been grown successfully without 
Bordeaux mixture in several areas of the State. 
Cooking quality fair. Introduced by Cornell Agri- 
cultural Experiment Station. 1 peck (15 Ibs.) by
