Endosperm balance numbers among New Guinea-Indonesian Impatiens species
Florist and Nursery Crops Laboratory, Horticultural Science Institute USDA, ARS. Beltsville, MD 20705
Abstract
The results of crosses among various plant accessions of impatiens species from the New Gulnea-Indonesian area support the endosperrn balance number (EBN) hypothesis. With few exceptions, oeses among plants with equal EBN's succeeded and those between unequal EBN's failed. Existing cross data Indicate that the present collection of New Guinea-Indonesian Impatiens is comprised of standard (2EBN) and tetraplold (4EBN) species.
