| Abstract/Contents: | "Buffalograss (Buchloë dactyloides (Nutt.) Engelm.) is native to the Great Plains region of North America. It exists as a ploidy level series of diploid (2n=2x=20), tetraploid (2n=4x=40), and hexaploid (2n=6x=60) individuals. The turf-type cultivar 'Tatanka' often has poor seed production and establishment vigor that may be due to unbalanced chromosome number and aneuploidy. Inbreeding my also be involved. Plants were collected from Foundation and Ceritfied seed fields of Tatanka, and ploidy level was determined using flow cytometry. Female plants in the foundation field were pentaploid and males were mainly hexaploid. Plants sampled from the certitfied field and seed from both fields yielded progeny over the range between 5x & 6x. Seed harvested from these fields exhibited significantly lower germination, bur size, and seed weight compared to other buffalograss cultivars. Inbreeding among parents of Tatanka may also play a role in redued germination and vigor. Adequate genetic diversity and uniform and balanced chromosome numbers should be carefully considered in the selection of parental clones for seeded buffalograss cultivars." |
