A COMPARISON OF VIRUS-FREE CLONES OF GOLDEN DELICIOUS
Four clones of Golden Delicious were compared with respect to pomological characteristics in three trials in several locations. Clone B was included in each trial. Trees of clone B were the most vigorous and had the highest production. Clone T.17 was comparable in all respects except that the fruit skin was much more russeted than that of clone-B fruits. Clone A showed a lower level of growth and production than clone B and the fruits were usually slightly smaller and more russeted. The clone "Smoothee" was quite interesting: the trees of this clone were more slender than those of the other clones and although growth and production were roughly the same as for clone A, the fruit size and smoothness were much better than for clones A and B.
