Abstract/Contents:"A laboratory assessment was made of cold tolerance in seven cultivars and one natural population of red fescue, overwintered at a lowland (30 m a.s.l.) or and upland (300 m a.s.l.) site. After 5 months overwintering, plants were exposed under laboratory conditions to seven freezing temperatures, -7, -9, -10, -11, -12, -13 and -15 C and +2 C as control. Thawed tillers were grown in soil in a glasshouse, and tiller survival and growth recorded after 28 days. Cold tolerance was estimated using LT 50 values. Tiller mortality increased with decreasing freezing temperature, with almost all tillers surviving at -7 C and almost all dying at -15 C. Cold hardening at the overwintering site markedly affected survival, plants overwintered at the upland site having significantly greater survival than those overwintered at the lowland site. All samples were affected to a similar extent by overwintering site. The samples Aber Valley, Hawk, Merlin, Polar, and Dawson were significantly more cold tolerant than Jupiter, S59, and Highlight. Tiller production data closely resembled those for tiller survival. For upland situations, cultivars or natural populations other than the currently recommended S59 have better cold tolerance, and may provide useful genetic resources for breeding cultivars for uplands use."
