Abstract

Grain amaranth (Amaranthus spp.) seed stocks are customarily from self-pollinating plants that open pollinate and are not F1 hybrids. However, cytoplasmic male sterility (CMS) traits are available for hybrid seed production. DB 199313 (Reg. No. GS-10, PI 686465) grain amaranth (A. hypochondriacus L.) is the first publicly available CMS line in Amaranthus. It is an F1 hybrid from a cross between male sterile plants of DB 921 (PI 568125) and male fertile PI 568179. Fertility can be restored by crossing DB 199313 with K432 (PI 538323). DB 199313 is adapted for seed production in Ames, IA, from direct seeding in the field, but it has not been selected for competitive agronomic performance. It provides a new publicly available genetic resource for improved grain amaranth crossing.
