Narrative
Sabine was selected and released because it produced more forage and was consistently more persistent under defoliation than common dallisgrass in multi-year forage evaluation plots in Louisiana and Texas. Its forage nutritive value is equivalent to that of common. Sabine differs genetically and morphologically from common dallisgrass. Sabine is a facultative apomict with a very low level of sexual reproduction; whereas, common dallisgrass is an obligate apomict. Sabine is a hexaploid with 60 chromosomes that pair during meiosis as 30 bivalents and common is a pentaploid with 50 chromosomes that associate during meiosis as 20 bivalents and 10 univalents. Sabine is more robust and grows more upright than common. Its leaves are bluish-green in color with some purple coloring at the tips of the blades. Because of the bluish color, its leaves normally appear darker than those of common. Besides the differences in their overall plant size and leaf color, the inflorescences of common and Sabine are distinctly different. Inflorescences of Sabine have more racemes (8-15) than common (3-5). The racemes of common dallisgrass usually are attached to opposite sides of the central axis of the inflorescence, essentially in one plane; whereas, those of Sabine are attached to the central axis in a spiraled arrangement. Seed set of Sabine was higher (52%) than that of common (21%). Sabine has the same amount of cold-hardiness as common dallisgrass and it may be slightly more cold-tolerant than common. Because the cultivar persisted in central Arkansas and northern Mississippi for four years, its area of adaptation may extend to northern Mississippi and southern Tennessee.

Pedigree
Description:
Sabine dallisgrass indirectly originated from PI 404826. This accession, PI 404826, differed phenotypically from the other accessions of the Uruguayan biotype and it was a facultative apomict that produced about 5% off-type plants. Sabine was selected from an off-type plant that came from PI 404826.
