Theme 03: Seed Production
Description
This study was conducted in an attempt to improve tolerance of annual ryegrass to Pythium ultimum Trow. Improved tolerance of ryegrass as measured in laboratory experiments was confirmed in greenhouse studies. This tolerance was defined as improved emergence and increased root length of seedlings in the presence of P. ultimum, using rolled germination paper in the laboratory, and sand in the greenhouse. Further experimentation will be required to determine usefulness of this selected trait under field conditions.
