(letenniiiatiuns mure than 50 milligranis of ascurbic acid for each 100-grani 

 sample of fruit. This high content for tomatoes is the full equivalent of 

 citrus fruits that can be grown only in subtropical regions. 



This new tomato variety of high vitamin C content has an indeterminate 

 or spreading vine. The very firm, red fruits ripen early, are smooth under 

 New Hampshire conditions, and seem somewhat resistant to cracking of 



the fruits. They average three to four 

 fruits per pound. The fruits have 

 the character for uniform ripening. 

 As a variety, Doublerich has popular 

 appeal to those home gardeners who 

 particularly appreciate the healthful 

 properties of a tomato rich in vit- 

 amin C. When made into tomato juice 

 or canned, the ascorbic acid is re- 

 tained well. Some tomato juice 

 assayed after having been stored for 

 one year still had 50 milligrams per 

 100 grams of juice. 



While Doublerich may not be gen- 

 erally adapted as a variety for suc- 

 cessful culture in those areas special- 

 izing in canning crops, it can serve 

 as a parent in a breeding program designed to originate new varieties of high 

 ascorbic acid content that will meet fully the requirements for processing.

New Hampshire Red Pickling Tomato 



Some tomato growers in southern New Hampshire produce green tomatoes 

 for pickles. The variety Red Pear which has been used for this purpose 

 has an indeterminate plant with fruits distributed at some distance along 

 the stems. The cost of harvesting green tomatoes for pickles is comparative- 

 ly high because of uneven maturity of fruits. For this reason, we decided 

 to produce a red-pear tomato on a determinate vine which would be earlv 

 and which would produce a large crop at one time so that the cost of 

 production could be reduced. 



The ordinary red-pear tomato was crossed with Fargo Yellow Pear, a 

 variety produced some years ago at North Dakota Agricultural Experiment 

 Station. The F^ -hybrids had a long vine and red fruits, and were pro- 

 ductive and early. Seed from them gave many kinds of plants: some were 

 determinate, some long, some with red fruit, some with yellow, some with 

 uniform fruit color and some with fruits having green butts, some late, 

 and some early. Selections were made from the early fruiting types with 

 a fairly small, pear-shaped, red tomato. Since this is a comparatively 

 simple breeding project, only two calendar years were required to com- 

 plete it, during which time one generation was raised in the field each 

 year and two in the greenhouse. The final result is New Hampshire Red 

 Pickling Tomato from which one can pick a thousand tomatoes of pickling 

 size per plant at one time. The variety has met with favor.
