Dendranthema Plant Breeding for Uniform Mounding Habit

The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled cross-pollination and subsequent selection processes. The breeder selected plants with desired combinations of traits (uniform mounding habit, decorative inflorescences, lavender ray florets) from the progeny and propagated them asexually to fix these parameters, achieving both improved inflorescence form and stable plant habit uniformity.

The patent resolves this contradiction by simultaneously selecting for both inflorescence quality and flowering time parameters. The breeder identified and selected plants that exhibited both desirable inflorescence forms and consistent flowering times, then propagated these selected plants asexually to stabilize both parameters together, achieving uniform flowering time consistency while maintaining high inflorescence quality.

The patent resolves this contradiction by selecting for multiple parameters simultaneously including floret color and winter hardiness. The breeder screened the progeny for both attractive lavender-colored ray florets and good winter hardiness, then selected and propagated plants that exhibited both traits, achieving a balance between aesthetic quality and winter hardiness reliability.

The patent applies preliminary action by first creating genetic diversity through controlled cross-pollination between two proprietary selections, generating a diverse progeny population. Then, the breeder performed preliminary selection of plants with desired traits before propagating them asexually. This sequence of actions (cross-pollination → selection → asexual propagation) ensures that trait stability is achieved through selection while the initial genetic diversity was utilized to create the desired uniform traits.
