INFLUENCE ON FLOWER COLOR BY PROPAGATION METHODS ON BEGONIA ELATIOR HYBRIDS

Many cultivars of elatior type begonias are found out as bud sports (bud mutations). And, often the variation of characteristics are recognized in grower’s field.

Checking the difference of characteristics by propagation methods, cultivar "Aurore" of Schwabenland type and "Aida" are recognized great variations of flower color by leaf cutting (in the case of cv. "Aurore" first generation: 100% changed the flower color, and second generation: also 100% changed the flower color from mother plant, in the case of cv. "Aida", first generation: 95.2% changed the flower color, and second generation: also 84.4% changed the flower color from mother plant). But, by top cutting, the variation of each cultivar are few (in the case of cv. "Aurore", both of two generations: no changed the flower color from mother plant, and, in the case of cv. "Aida", first generation changed only 7.2%, also second generation changed only 1.7%, it from mother plant).

Therefore, especially these two cultivars must be propagated by top cutting for keeping stability of the characteristics.
