The Extent of Aberrants Produced by Merion Kentucky Bluegrass, Poa pratensis L., as Determined by First and Second Generation Progeny Tests1

  1. J. M. Duich and
  2. H. B. Musser2



Aberrants produced by Merion Kentucky bluegrass averaged from 2.8 to 4.2% in 2 generations of progeny tests. Aberrancy from plural seedlings averaged 12.3% from the less than 2% polyembryos produced. Only 19% of the aberrants were found to be plus or equal. Second-generation progeny tests are necessary and valuable for verification of first-generation classifications and obtaining information on advanced-generation performance.
