摘要：To evaluate the yield and yield components of lentil genotypes under drought stress conditions, an experiment was conducted in Ardabil Agricultural Research Station during 2005 in a split-plot experimental design based on Completely Randomized Block Design (CRBD) with four replications. The treatments included four irrigation levels [(I1) irrigation on the basis of 60 mm evaporation, (I2) irrigation on the basis of 80 mm evaporation, (I3) irrigation after 100 mm evaporation from basin class A, and (I4) no irrigation] as the major factor and three lentil genotypes (Ardabil local variety, ILL4400 and ILL6212) as the minor factor. The results showed that irrigation water deficit during lentil flowering led to the decrease in pod number, grain number per plant, grain weight, grain yield and harvest index, so that I2 level of genotype ILL4400 had the highest yield followed by ILL 6212 and Ardabil local variety and I4 had the lowest yield. I3 level of ILL6212 had the highest harvest index and genotypes ILL4400 and ILL6212 had the highest grain number per plant.
