one-half pints per foot of row was recorded for a 50-foot row grown in clean 

 cultivation. New Hampshire responds to heavy fertilization and produces an 

 ample number of sucker plants, though it tends to sucker less than some 

 varieties. Many of the suckers tend to arise three and four feet from the 

 parent plant and these may be readily controlled by cultivation or this fact 

 must be taken into account when a nurseryman wishes to propagate large 

 numbers of plants. While New Hampshire cannot be rated resistant to com- 

 mon raspberry diseases, with good cultural practices it is proving a fine 

 commercial kind for New Hampshire and is liked by the home owner. 



Success Purple Raspberry 



Another selection from the second generation mentioned above under the 

 New Hampshire raspberry was designated NH :#100, a much-branched, low- 

 growing three-foot-tall, red raspberry. While this selection failed to become 

 popular under further testing, it served as a pollen parent in breeding work. 

 Morrison black raspberry was pollinated by NH 4^100. A progeny of purple 

 raspberries resulted. Six of the best seedling selections were propagated for 

 row tests. After testing both on the Station grounds and elsewhere, NH 

 :f^P-4 was chosen for naming. The name Success was given to this new 

 variety introduced in 19.56. The medium to large size purple berries are 

 sweet, being less tart to the taste as fresh fruit than are most kinds of the 

 purple raspberry. The flavor is excellent as fresh fruit and excels for both 

 frozen and canned products. Flavor of the canned fruits has been compared 

 to the Loganberry. Many who have tried the Success raspberry prefer its 

 flavor to all other kinds. The flavor resembles the black raspberry somewhat, 

 though it is distinctive in itself. 



The plants are highly productive. Eleven plants in a private garden lightly 

 pruned to trellises yielded 120 quarts of fruit in 1956. The strong-growing 

 arched canes exceed six feet in height and some canes may measure 10 to 

 ] 2 feet to the tip when allowed to grow freely. The tips of the canes may 

 root late in the fall. Also the plants produce some sucker shoots after the 

 plants have become well established. Both of these means may serve for 

 jjropagation. When large plants have been dug up for transplanting, many 

 young plants are regenerated from roots remaining in the soil. Resort has 

 been made to 



softwood cuttings of 



the primocanes to hasten the increase 

 of this variety. Such cuttings taken in 

 July and placed in either a mist- 

 nozzle or Wardian case propagation 

 frame give rooted plants, the strong- 

 est of which may be field planted; 

 others may be wintered successfully 

 in a cold frame where they may be 

 mulched with sawdust to be planted 

 in the open field the following spring. 

 Success raspberry has been resist- 

 ant to spur blight, a serious disease of 

 the red raspberries. It is not immune 

 to anthracnose which frequently 

 bothers black raspberries. Plants of 



Success raspberry, a purple variety of 

 unusual quality and high productivity.
