Abstract

Lentil (Lens culinaris Medik) enjoys the second largest cultivation area among all planted pulses in Khorasan Razavi Province. In order to investigate the effect of drought stress on yield and yield components of selected lentil droughttolerant genotypes, a split-plots experiment has been carried out with three replications at research field of Ferdowsi University, Mashhad, Khorasan Razavi Province, during 2012-13. The main factor is the two irrigation levels: Nondrought stress and drought stress (providing 100% and 40% of water requirement), while the sub-factor includes nine genotypes. Results show that under non-stress conditions, the number of seed per pod, number of pods per square meter, harvest index, seed yield, and biological yield in MLC356 genotype have been significantly higher than other genotypes. However, under drought stress, the last two traits show a severe reduction. Under stress conditions, the highest and lowest levels of both maximum quantum efficiency of photosystem II and economic water use efficiency belong to cabralinta and MLC121 genotypes, respectively. Also, it is determined that the number of fertilized pods per plant and 1000 Seed Weight have been the most important traits to affect lentil yield.
