Use of Self-Incompatibility to Produce Commercial Seed-Propagated F1 Bermudagrass Hybrids1

Many clones of bermudagrass exhibit a high degree of self-incompatibility. Most of these appear to be crosscompatible. Six superior clones set an average of six times more seed when mutually pollinated with the other five clones than when selfed. Four of the 15 diallel (mutual pollination) crosses involving these six clones tested in plots established from seed yielded as much (or more) forage as the best vegetatively propagated clone in the test. One clone, unrelated to the others, gave high-yielding hybrids and high general combining ability effects when crossed with the other five dories. Commercial F1 hybrid seed could be produced by harvesting all seed from a field vegetatively planted to alternate rows of two such clones. These clones may not yield enough seed, however, to make hybrid bermudagrass seed production competitive with alternate land uses in Arizona.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
