CLONAL SELECTION, FERTILITY AND FRUIT QUALITY OF GOLDEN DELICIOUS
Attention was payed to the testing of the apparently different clones of Golden Delicious, standard and spur. Differences between the various mutants were demonstrated as regards fruit weight, skin color and russeting, firmness, soluble solids, acidity and keeping-quality in cold storage. Also a certain positive correlation was found between russeting, amount of sugar and susceptibility to shrivelling after cold storage.
It is interesting to note that in certain aspects some new mutations of Golden Delicious are preferable to a virus free selected clone and that even though the quality of the fruit is sometimes slightly inferior to that of Golden Delicious, some spur clones have estremely important characteristics which make them equally worthwhile for new high density planting.
