Assessment of perennial ryegrass (Lolium perenne L.) for breeding. II. Components of winter hardiness

  title={Assessment of perennial ryegrass (Lolium perenne L.) for breeding. II. Components of winter hardiness},
  author={Mervyn O. Humphreys},
When breeding for good winter hardiness a broad range of adaptations must be considered. Such a multitrait approach requires some understanding of physiological and genetical relationships between relevant traits. Fourteen winter related characters were measured on field grown plants from 86 perennial ryegrass accessions originating from a wide range of climates. Genetic components of variance and covariance were extracted from the data and a principal components analysis carried out. The first… CONTINUE READING
