Breeding Narcissus for cut flower production

, : Breeding Narcissus for cut flower production. Acta Horticulturae (47): 173-178

At Rosewarne narcissi are being bred to fill the 6-week gap between the Rijnveld's Early Sensation, flowering in early January, and Golden Harvest in mid-February. The requirements are tall stems at the gooseneck stage of flower opening, fat buds, clear colours, trumpets or large cups which would respond to pre-cooling and forcing, with high yields.

Among the Liliiforae with bulbs or corms the number of foliage leaves is often reduced to 1 in flowering plants. Among the Amaryllidoideae, however, this reduction occurs only in Narcissus and Braxireon (= Tapeinanthus). At their autumnal flowerin...
