Double-flowering New Guinea Impatiens

Abstract

New, distinct and stable cultivars of double-flowering New Guinea Impatiens (NGI) are disclosed. Double-flowering NGI produce one or more flowers with at least seven full or partial petals per flower. Double-flowering NGI cultivars are disclosed in which substantially all the flowers produce at least 7 full or partial petals per flower. The double-type flower characteristic has been successfully bred into all single-type (5 petals per flower) or semi-double-type (6 petals per flower) NGI cultivars thus far tested. The double-type flower characteristic has been combined with many desirable NGI traits including different flower colors, leaf colors, leaf variegation, and growth habits. Methods for the reliable breeding of the double-type characteristic into diverse single-type or semi-double-type NGI genetic backgrounds, as well as methods for increasing the degree of doubleness per flower or plant, are disclosed.
