Narrative
First release of naturally occurring tetraploid Russian Wildrye germplasm. Previous work limited to tetraploids artificially induced from diploids. Seeds heavier, 0.53 g 100 seeds-1. Seedling vigor greater, rate of emergence at depth of 7.6 cm is 3.4 seedling/day. Stature taller, 103 cm. Leaves longer and wider, 15.2 x 5.6 cm. Dry matter production and crude protein similar to current cultivars under different environments. Water-use efficiency better than diploids as determined by carbon isotope discrimination measurement.
