【 摘 要 】

Excised-leaf water retention capability of spring wheat and winter wheat were tested. Cultivar differences were well differentiated when the decrease in leaf water content % was between 11 and 30. An increase in excised-leaf water retention capability and a decrease in leaf water content were seen during winter compared to summer. Drought hardened plants showed higher water retention capability. Excised-leaf water retention capability of the progenies from three crosses of winter wheat were evaluated. Frequency distribution patterns of the progenies showed the characteristic pattern of quantitative inheritance. Excised-leaf water retention capability of wheat seems to be a quantitative character governed by polygene action.
