Abstract
Ten chemical characters and crown LT50s were measured on 14 cold-hardened cultivars of winter wheat (Triticum aestivum L. em. Thell.) to determine their usefulness in winter survival prediction tests. Differences among genotypes with a range of cold hardiness potential (LT50 −13 °C to −20 °C) were significant for 6 to 10 characters evaluated. Crown LT50 was the best prediction of field survival (FSI). Cell sap viscosity, total crown nitrogen, crown ethanol, insoluble nitrogen, and crown uronic acid were highly correlated with both FSI and LT50. Proline, pH and ATP were not significantly correlated with either FSI or LT50.Key words: Chemical tests, selection, winterhardiness, wheat
