Technical Abstract: Hairy vetch (Vicia villosa L.) is a major leguminous cover crop utilized in the United States. The high incidence of hard seed in the species is a limitation to farmer acceptance of this species. Furthermore, economic viability of seed production of this crop is hampered by the high incidence of shatter in the species. We report here on the initial phases of a program to develop soft-seeded non-shattering hairy vetch. This program has a two-pronged approach that includes 1) breeding for soft seed and non-shattering hairy vetch and 2) determining underlying genes for hard seed and shattering in hairy vetch. So far, in the project rapid phenotyping assays have been developed and evaluated. Two GWAS seed production evaluation nurseries were established and are under evaluation in Texas and Oregon. Efforts are underway to create a hairy vetch reference assembly. A rapid inexpensive PCR-SSR-amplicon genotyping assay has been developed for routine genotyping to assist in the program. A first cycle of phenotypic selection for soft-seeded hairy vetch is in progress.
