By September, the answer to the problem was obvious. The 

 bushes treated with iron had. dark green foliage and had made good 

 growth. The bushes treated with the other materials made only 

 limited growth, had small leaves, and had now developed the typi- 

 cal interveinal chlorosis symptom of iron deficiency. 



If your blueberry bushes are not producing well, making little 

 new growth, and have pale, yellowish leaves, they could be suffer- 

 ing from "iron deficiency anemia."

MISNAMED TREES AND PROPAGATION OF THE UNKNOWN 



James F. Anderson 

 Department of Plant and Soil Sciences 



As reported in the January-February, 1972 issue of Fruit Rotes , 

 one of the major problems encountered in our variety evaluation 

 program is that of misnamed trees. The problem is most acute in 

 our peach testing program, where we have had instances when up to 

 25% of the trees of one variety were not true- to-name ; in other 

 instances, we have had a complete substitution for the variety. 

 We have also discovered mixtures in our apple blocks. One of the 

 most serious problems is in our Red Delicious strain test orchard, 

 where a complete substitution for one strain, and substitutions of 

 one or two trees in two other strains have been found. This could 

 lead to an inaccurate evaluation of a variety or strain. I am 

 sure that this problem can occur in commercial orchards. 



Mixtures can develop during several stages of the nursery op- 

 eration and during the planting operation in the growers' orchards. 

 Many of the maj or nurseries have their trees inspected for trueness- 

 to-name and this eliminates most of the mixtures that have occurred 

 as a result of budding and/or staking errors. Unfortunately, the 

 budsport strains of apple varieties are indistinguishable from 

 their parent variety and other strains in the nursery row. 



Mixtures that occur during the digging and shipping process or 

 when the trees are planted in the grower's orchard will probably 

 not be noticed until the trees have begun to fruit. 



It is not uncommon for a grower to forget or lose the variety 

 names of some trees in his orchards. These trees may have proven 

 to be very profitable and he wishes to plant more of them. In 

 such an instance, we would suggest the grower make arrangements 

 with a nursery to custom-bud the number of trees desired.
