Evaluation of Annual Clover Ecotypes by Using Drought Tolerance Indices

To evaluate clover ecotypes by using  drought tolerance indices, 17 annual clover ecotypes were tested in a split-plot experiment by using randomized complete  block design with three replications, under two irrigated and rain-fed conditions in the Saatlo Research Station in Urmia, Iran. In this study, based on the dry matter yield in stressed (Ys) and non-stressed (Yp) conditions, quantitative values of drought tolerance indices of mean...
