More extensive rhizomatous growth than T. sarosiense. Purple flowers with heads elongate. Self-incompatible but set less crossed seed than parents. Kidney shaped seeds.1451946PI 556974
1PI 556975Trifolium hybr. United StatesW6Not Available1991DEVELOPEDPRE 10/21/1991Breeding materialHybrids are male and female fertile and self-incompatible producing less crossed seed than parents. Diploid chromosome ranges from 58-60. Pollen stainability averages 89%. Purple flowers and globose heads. Strongly perennial and have rhizomatous growth. Yellowish-brown kidney-shaped seeds and weight 27 mg/10 seeds. Field evluations indicated no obvious agronomic superiority of the hybrid over the the best of the T. medium genotypes.1451947PI 556975
