| 0 | GSHO 3641 | mov1.f | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | This mutant has four carpels and two sepal-like structures where the lodicules should be. Stamens and lodicules are absent. The plant appears normal, but is completely sterile. The stock must be maintained as a heterozygote. | 1913949 | GSHO 3641 |
| 1 | GSHO 3642 | mov2.g | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | This mutant has between five and seven carpel-like structures and normal lodicules. Stamens are not present, but some carpels are terminated with stamen-like structures. The plant appears abnormal with a twisted and compact spike and reduced awn length. The stock must be maintained as a heterozygote. | 1913950 | GSHO 3642 |
| 2 | GSHO 3643 | mov4.k | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | Not Available | 2013 | DEVELOPED | | | | | | Genetic material | The mutant spikelet has two carpels, two anthers, and two lodicules. One of the anthers appears to have been converted to a carpel in some spikelets. Mutant plants are often difficult to identify. | 1913951 | GSHO 3643 |
| 3 | GSHO 3644 | tst1.c | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | Not Available | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plants and spikes appear normal except there is no seed set in the tip of the spike. | 1913952 | GSHO 3644 |
| 4 | GSHO 3650 | sun1.a | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plants appear extremely susceptible to loose smut caused by Ustilago nuda. | 1913958 | GSHO 3650 |
| 5 | GSHO 3652 | bsp1.a | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plant appears normal except for a very bush spike caused by many awn-like structures. Spikelets lack reproductive tissue and are completely sterile. The mutant must be maintained as a heterozygote. | 1913960 | GSHO 3652 |
| 6 | GSHO 3653 | lam1.a | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plants have a very prostrate growth habit and heading is delayed to very late in the season, and sometimes do not head. During juvenile stages before the reproductive phase is induced, plants have very narrow, long leaf blades. Leaves produced during the reproductive phase have wide, short leaf blades. The mutant in Steptoe has a winter growth habit. Maintained as a heterozygote. | 1913961 | GSHO 3653 |
| 7 | GSHO 3654 | asp1.a | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plants appear normal except the spike is rudimentary or missing. a few spikelets are formed occasionally, but are mostly sterile. The stock must be maintained as a heterozygote. | 1913962 | GSHO 3654 |
| 8 | GSHO 3655 | ovl2.b | Hordeum vulgare L. subsp. vulgare | Washington, United States | NSGC |  | Not Available | 2013 | DEVELOPED | | | | | | Genetic material | Mutant plants appear normal except carpels are rudimentary and female sterile. Anther development is normal and pollen is viable. Maintained as a heterozygote. | 1913963 | GSHO 3655 |
