This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

0PI 659700'Gadsby'Hordeum vulgare L. subsp. vulgare Alberta, CanadaNLGRPNot Available2010DEVELOPED2010CultivarRough awned, two-row, hulled, general purpose barley. As a seedling, has semi-erect growth habit with a green coleoptile of intermediate length. Leaf sheath and blade are glabrous and green in color at both the seedling and booting stage. By the booting stage, its leafves have a light waxy bloom. Its flag leaf has a pronounced waxy bloom, is glabrous and of medium legth and width, with an intermediate attitude. Auricles are purple colored and glabrous. Its stem is thick, with pronounced waxiness, medium green color and exerts 5 to 10 cm after heading. Its collar is platform shaped. Its culm neck is slightly curved. Has a tapering spike of medium density and length, with a horizontal attitude, and no waxiness. Its sterile spikelets are strongly divergent. The first rachis internode is short with a slight curve. The rachis margin is moderately pubescent. The glumes are medium long with a band of medium length glume hairs. The glume awns are equal in length to the glume. The lemma awns are longer than the spike. Both glume and lemma awns are rough with purplish tips. The lemma's lateral veins are glabrous. The lemma nerve color is green. The kernel has a mid-long rachilla with short rachilla hairs. The kernel has a white aleurone and is of medium length and width with a horseshoe basal marking. The lodicules are clasping. Resistant to the surface-borne smuts and to true loose smut. Was rated as moderately resistant to the spot form of net blotch but moderately susceptible to the net form. Was rated as moderately susceptible to spot blotch. Was rated as moderately resistant/moderately susceptible to Fusarium head blight (scab), common root rot, and stem rust. Was rated as susceptible to septoria or speckled leaf blotch. Resistant to scald. In 2 years of FCDC yield trials for cultivar comparison, showed a yield advantage of 12% over Seebe and 4% over Busby, although Xena had 3% higher yields. Reached anthesis at the same time as Seebe, approx. 4 d later than Busby and 3 da later than Xena. Reached maturity 2 d earlier than Seebe, although it was later than Xena by 1 d and Busby by 2 d. Its kernel weight was heavier than those of Seebe, Busby or Xena, and test weight was intermediate to Seebe and Busby. Percent plump was slightly higher than Busby and Seebe, and much higher than that for Xena. Similar in height to Seebe and Busby but taller than Xena. Biomass yields (dry matter at the soft-dough stage timed to simulate harvest for silage production) did not differ between these 4 cultivars. Had excellent water use efficiency (WUE) when based on biomass, but had lower WUE when based on grain yield.1846640PI 659700
