Novel, high yielding stable Mentha arvensis plant named ‘Damroo’

Abstract

A novel Mentha arvensis mint population-variety "Damroo' capable of producing viable seeds and phenotypically homogeneous seed-derived plant population when cross pollinated within its own population and capable of high yield of mint oil.

We claim:  
     
       1. A new and distinct cultivar of  Mentha arvensis  plant named ‘Damroo,’ substantially as herein illustrated and described, having the following characteristics: 
       (a) dark greenish leaves (137A), white to whitish purple (76D) petals, and branching providing a pyramidal habit;  
       (b) tolerance to leaf spot, rust, and powdery mildew;  
       (c) essential oil containing 78-80% menthol and 12-17% isomenthone;  
       (d) seed yields in the range of about 90-96kg/hectare; and,  
       (e) the capacity to retain homogeneity of plant traits, despite out-crossing within the population.
