Abstract

Background and objectives: In Iran, lentil cultivation is usually done in spring and rain fed conditions. Sowing in low soil temperature at the end of winter to early spring is one of the problems of spring cultivation in Iran. Grain Yield can be increased by replacement lentil cultivation in autumn instead of spring cultivation. The results of a research in Iran showed that autumn sowing with cold tolerant lentil genotypes could achieve the Yield of two to six times effective than spring sowing (1). Identification lentil genotypes with cold tolerance potential are one of the suitable strategies for success in autumn lentil cultivation. Therefore, this experiment was designed to select cold tolerant genotypes of lentil in field conditions. Materials and Methods: In this study, the cold tolerance of 253 lentil genotypes was evaluated in 2015-2016 on Research Center for Plant Sciences, the Ferdowsi University of Mashhad based on Augmented designs. Planting was done in the early of November. The lowest temperature during this period was-5. 9 ° C. During the growing season, the phenologic stages of the plants and the Survival percentage were recorded under effect of cold temperature of winter. At the end of the growth season, in five randomly harvested plants, Morphological traits, Yield, and Yield components were measured and recorded. Results: The rate of Survival percentage (SU %) was varied between 0 to 100%. The highest Survival percentage (100%) was observed in MLC8. The maximum grain Yield (88 g m-2) and biomass Yield (535 g m-2) were obtained from MLC415. The highest length in a plant (41 cm) was observed in MLC291. The maximum number of filled pods (83 filled pods per plant) and maximum hollow pods (72 hollow pods per plant) were observed respectively in MLC218 and MLC72. Conclusion: Based on results, 23 cold tolerant genotypes among 253 lentil genotypes with the highest cold resistant in vegetative and reproductive growth periods were identified and selected. However, due to mild winter, the further experiment is necessary for identification of cold tolerance lentil genotypes.
