Double-flowering New Guinea Impatiens

A method for the breeding of double-flowering New Guinea Impatiens plants that produce one or more flowers with at least 7 full or partial petals per flower comprising the steps of:

• a. crossing a first single-type plant having doubleness in its genetic background, either as the male or female parent to:
• i. a semi-double-type plant;
• ii. a double-type plant;
• or
• iii. a second single-type plant having doubleness in its genetic background;
• b. selecting F1 progeny that are single-type, semi-double-type or double-type;
• c. crossing said F1 progeny that are single-type, semi-double-type or double-type to:
• i. a second double-type plant;
• ii. a second semi-double-type plant;
• or
• iii. a third single-type plant having doubleness in its genetic background;
• and
• d. selecting double-flowering progeny.
