Popis: | Glaucous Altai wildrye grass, Leymus angustus (Trin.) Pilger, has been reported to exhibit higher seed yield than the normal green phenotype. Seed quality is correlated with successful seedling establishment. Our objective was to determine the seed yield and quality of three half-sib populations of Altai wildrye that differed in visible glaucousness. Seed was harvested from 60 glaucous, 60 non-glaucous, and 60 variably glaucous half-sib lines over 3 yr at a semi-arid location. Seed yield, seed weight and germination was greater from glaucous lines than the nonglaucous lines. Key words: Glaucous, range improvement, seedling establishment, epicuticular wax |
