SOME HANDLING AND STORAGE PROBLEMS OF 'IDARED'

'Idared' is an attractive, high-yielding apple variety 

 resulted from a cross of 'Jonathan' and 'Wagener' in Idaho, 

 some areas it has been widely planted in recent years, with 

 utation as a good-keeping apple with few storage problems, 

 of problems with internal breakdown of 'Idared' prompted an 

 tigation of its characteristics in New York.

Jonathan spot : 'Jonathan' was one parent of 'Idared,' and 

 like its parent th'-s variety, especially if picked late, can devel- 

 op Jonathan Spot in storage. However, if picked at the proper 

 time, the-oroblem should be minimal, and if stored in CA (3% Op. 

 11 CO2, 32 F) the problem has not developed. 



Freezing damage : Since this is a late variety, the danger of 

 freezing in the orchard exists. In fact, freezing occurred in 

 1969 and in 1972. Samples that had been frozen were stored and 

 observed. Freezing reduced their firmness at harvest, but in gen- 

 eral the apples recovered remarkably well. Whereas varieties like 

 'Northern Spy' developed much breakdown by January, 'Idared' did 

 not. However, by late spring they did show breakdown, testifying
