    • 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.
    • 披露了双开花新几内亚凤仙花(NGI)的新鲜,鲜明和稳定的品种。 双花NGI生产一朵或多朵花,每朵花至少有七个全部或部分花瓣。 公开了双开花NGI品种,其中基本上所有的花每朵花产生至少7个全部或部分花瓣。 双花型特征已经成功地育成了迄今为止测试的所有单一类型(每花5瓣)或半双型(每花6瓣)NGI品种。 双花型特征与许多理想的NGI性状相结合,包括不同的花色,叶色,叶杂色和生长习性。 公开了将双型特征可靠地育种成多种单型或半双型NGI遗传背景的方法,以及增加每朵花或植物多样性程度的方法。
