Evaluation on Drought Resistance of Native Sickle Alfalfa Germplasm Collected from Different Parts of China

39 accessions of sickle alfalfa (Medicago falcata L.) collected from different regions of China were evaluated for their tolerance to drought. Differences were observed among accessions in their reactions to drought and 8 good tolerant accessions at populations level and 18 excellent tolerant accessions at individual level were identified based on drought response index (DRI).
