SOME COMMENTS ON PAPERS READ AT THE SIXTH INTERNATIONAL GRASSLAND CONGRESS.

This article comments on the papers presented at the Sixth International Grassland Congress held in State College, Pennsylvania from August 17 to 23, 1952. A large proportion of the papers in the Genetics and Breeding Section were of the cytogenetics type in that they reported investigations of the breeding behavior of certain species and hybrids. The significance of this may be in the fact that methods based on selection within mixed population and subsequent strain building from basic plants, after tests of combining ability, have explored fairly thoroughly the available material within a few of the more common species.
