Patent ID: 8383881

Claim:
A method for producing polyploid plants of orchids comprising: (a). providing at least one protocorm or protocom-like body (PLB) of an orchid, with the protocorm or PLB having an upper portion with a growing point and a lower portion without any growing point, with the lower portion having a plurality of polyploidy cells; (b). cutting the protocorm or PLB at a predetermined point to separate the upper portion and the lower portion, wherein the upper portion has a first cut surface and the lower portion has a second cut surface, and removing the upper portion having the growing point; (c). subculturing the lower portion of the protocorm or PLB without any growing point in an inducing medium to induce the growth of the plurality of polypoidy cells, wherein one or more next-generation PLBs grow from the second cut surface of the lower portion; (d). cutting off at least one of the one or more next-generation PLBs from the second cut surface of the lower portion; (e). repeating (b) through (d) one or more times; and (f). subculturing the next-generation PLBs obtained from (d) or (e) in a regenerating medium to differentiate the next-generation PLBs into plantlets and identifying the plantlets of the next-generation PLBs.
