ASEXUAL PROPAGATION OF GENETIC-CYTOPLASMIC MALE STERILE AND/OR OTHER ONION LINES

摘要

A tissue culture process for the asexual propagation of plants of the genus Allium is described and claimed. The method involves culturing, on first and second culture media, immature flower buds obtained from umbels of the plants prior to opening of the umbel spathes. The method provides many more plants than other methods of asexual propagation and permits use in hybrid seed production of genetic-cytoplasmic male sterile plants for which no genetically similar maintainer lines are available.
