Agricultural Research in New Hampshire 37 



Sending materials to M.I.T. for analysis has required too much time, 

 hence it will be necessary to secure new equipment locally available for 

 making analyses before this project can be continued satisfactorily.

Fruit Varieties 



Medina is a new apple variety which shows considerable promise. In 

 the trial plots at Durham Medina has borne early, has produced larger 

 apples than Delicious which it somewhat resembles, and has kept unusual- 

 ly well in storage. 



Among raspberry varieties, Viking is more resistant to spur blight 

 than Latham or Taylor, but apparently its rest period is more easilv 

 broken; hence, there was more winter injury on it than on the other two 

 varieties in the winter of 1945-46. Latham suffered less winter injurv than 

 the others despite its fairly heavy infestation with spur blight. 



Winter killing in cherries was very severe this past winter and was 

 closely correlated with the amount of leaf-spot injury during the summer 

 of 1945, when many varieties were completely defoliated. Varieties 

 which were most resistant to leaf spot, and which survived the winter in 

 the best condition, were Belle Magnifique and Sweet September. 



Oriole, Cumberland, and Colora peaches have again come through 

 the winter with the largest number of live fruit buds. 



The Mcintosh variety of apple shows the heaviest infection with 

 apple scab that has occurred in many years, enough so that considerable 

 defoliation has resulted, despite an ordinarily adequate sprav program. 

 Cortland is apparently more scab resistant. 



Of the grapes on test, Van Buren shows the greatest resistance to 

 black rot, which disease practically destroyed the crop on most of the 

 other varieties. Blue Jay is to date outstanding among the Minnesota hy- 

 brids. Moonbeam, Bluebell, and Red Amber have not proved as desirable. 

 Bluebell has not been winter hardy. Red Amber and Moonbeam do not 

 ripen properly before frost. Kendaia is winter hardy and vigorous, but 

 has not produced as well as was expected. The quality of Kendaia is high. 

 Fredonia is very satisfactory and is winter hardy, but the bunches are 

 relatively small.

Fruit Plants in Northern New Hampshire 



Apples and pears have done better than other tree fruits in Coos 

 County, particularly south of Stratford. Winter injury becomes serious 

 fiom Colebrook northward. The best apple and pear trees were found in 

 the town of Dummer at a high elevation and on a slope protected from 

 cold west and northwest winds. Cortland seems hardier than Mcintosh 

 in this area, as evidenced by the fact that injury to this variety was found 

 only at Pittsburg. Anoka has done the best of all varieties on trial, and 

 Cortland seems somewhat hardier than Beacon. The Duchess variety 

 and the Florence and Dolgo crabapples have done well. Prairie Spy 

 showed considerable winter injury throughout the area.
