New Hampshire Red Raspberry 



As reported in New Hampshire Station Bulletin No. 383. Taylor red 

 raspberry was pollinated within a screened greenhouse in the spring of 1943 

 with pollen of Ruhus chamaemorus, the baked apple berry. Open-pollinated 

 seeds were saved in the field from the small red-fruited first generation 



plants that grew about two feet tall.

 somewhat branched 

 plant was selected and called NH 

 ^101 (also carried by some cooper- 

 ators as NH 4/^104). Hardy and pro- 

 ductive, this selection which was 

 named New Hampshire and introduc- 

 ed commercially in 1955, has large 

 conic red berries with a long slender 

 torus or receptacle. This makes for 

 rapid harvesting of the easily-picked 

 berries that are outstandingly firm. 

 The bright red berries have good 

 flavor fresh and also canned or fro- 

 zen. The fruits ripen towards mid- 

 season, but the picking period ex- 

 tends over a period of several weeks. 

 In 1956, the first picking came on 

 July 23 and the last harvest was made 

 August 24. A total yield of three and
