Evaluation of the Rate of Excisedleaf Water Loss Used as an Indicator of Drought Resistance in Wheat

doi:10.3321/j.issn:1000-7091.1997.04.011

Abstract

Abstract: The results of China-Canada joint study on rate of water loss of wheat leaf were analysed. Rates of excised leaf water loss of the typical materials selected from the study of drought resistance genetic pattern in winter wheat were tested in project laboratories in both China and Canada. The result showed that repeatability among different replications which were carried out by the same testers was high, while the same testing materials resulted in lower repeatability among different tester. Correlation between rate of excised leaf water loss and crop yield on dryland was not found. Therefore, it was still premature to use the rate of excised leaf water loss as an indicator for drought resistance selection in wheat.

Key words: Wheat, Rate of excised-leaf water loss, Drought resistance, Indicator
