Narrative

Considerable phenotypic variability exists among plants of Polar because of wide genotypic base of the parent clones. About 5% have very pubescent and 60% slightly pubescent nodes. About 75% of the lemmas are slightly to extremely pubescent. Less susceptible to lodging and spread by rhizomes somewhat less vigorously than most cvs. Outstanding winterhardiness in Alaska and produces consistently high forage yields.
