Drought tolerance in winter cereals609904Summary: In a trial of 16 genotypes in the laboratory and the 3 field sites in Southern Italy, grain yield/ha was more closely correlated with electrolyte leakage under osmotic stress (r = 0.69) than with germination in an osmotic solution or seedling dry matter increase after thermal stress. The average yield in field tests, conducted at 3 sites subject to drought, of genotypes with high scores in the physiological tests was 15 higher than the average yield of the discarded ones. Only Georgie showed good scores in all 3 tests. Scores in the tests were not correlated with each other, suggesting the existence of independent machanisms. A high proportion of 2 row
