Abstract
The mutlivariate analysis of four year records on several vegetative and productive traits of twenty-one apple mutants (3 of ‘Jonathan’, 3 of ‘Ozark Gold’, 14 of ‘Mollie’s Delicious’, 1 of ‘Neipling’s Early Stayman)’ induced by gamma radiations showed that observation of some traits of one-year-old shoots is the most efficient way to reveal compact growing apple mutants.
In particular, basal cross-section area, total length and leaf area resulted the most appropriate parameters, while internode length together with conopy height and width are less appropriate.
In particular, basal cross-section area, total length and leaf area resulted the most appropriate parameters, while internode length together with conopy height and width are less appropriate.
The most interesting mutants we found are: one of ‘Mollie’s Delicious for the best balance among tree and fruit traits and for high skin color; one of ‘Neipling’s Early Stayman’ with an earlier and more extensively red colored apple than the original clone.
