ABSTRACT:
TYPE OF PLANT AND NAME OF VARIETY
The present invention relates to a new and distinct variety of peppermint plant of the species botanically know as
Mentha piperita L.
I have named my new variety “Cascade Mitcham.”
DISCOVERY AND ASEXUAL REPRODUCTION
This new peppermint was developed in a mint breeding program in which the primary objective was to develop a Mitcham type peppermint variety having acceptable oil quality and increased resistance to mint wilt caused by the soil-borne fungus,
Verticillium dahliae
. The new plant was discovered in a cultivated area on land near Albany, Oreg., and was initially identified as 84-M0107-4.
Selection 84-M0107-4 originated as a seedling from a polycross where M0107, a polyploid Mitcham peppermint plant, was the female parent. Polyploid male parents served as the pollen donors. MIRC M0107 is a seed fertile peppermint plant donated by the A.M. Todd Company of Kalamazoo, Mich., to the Mint Industry Research Council (MIRC) for a mint breeding program. Dr. M.J. Murray of the A.M. Todd Co. developed M0107, an unselfed polyploid peppermint strain of his selection 71-257 and later identified as selection 58. Selection 58 is a mutant created by irradiating Black Mitcham peppermint stolons and was released in 1972 as Todd's Mitcham peppermint.
Asexual reproduction of 84-M0107-4 was conducted each year under my direction since 1984 at a research farm and greenhouses near Albany, Oreg. Asexual reproduction has been conducted by rooting stem cuttings and by planting stolons taken from field grown plants. Characteristics of 84-M0107-4 come true to form and are established and transmitted through vegetative propagation.
