Abstract: 

Existing restrictions in spring sowing of chickpea (Cicer arietinum L.) as dry farming have made the study of Entezary sowing unavoidable. However, lack of suitable varieties of chickpea has endangered this system of sowing. This study was conducted at the Experimental station of Faculty of Agriculture, Ferdowsi University of Mashhad for two years (1997-99) to evaluate the reactions of 315 of Kabuli Chickpea germplasm to Entezary sowing. Ten seeds of each accession with a distance of 10cm were planted in rows with 50 cm apart without replication. Two planting dates were chosen in the late November and late December in 1997-8 and 1998-9 growing seasons. To determine the percentage of survival, seedlings were counted after winter. At the first sowing date of 1997-98,45.5% and in the second sowing date 51.8% of accessions were highly tolerant (rank 1) and / or tolerant (rank 2). In contrast in 1998-99 at first sowing 54.8% and second sowing 60.0% of accessions were high tolerant (rank 1) and / or tolerant (rank 2). Cold severity and duration in the first year were higher than those in the second. Therefore, a large number of accessions were killed. At first sowing date in both years, 84 accessions and second sowing date 110 accessions ranked 1 and / or 2.25 and 20 accessions (at date 1 and 2, respectively) selected on basis of survival index, yield per plant, weight of 100 seeds and tolerance to Ascochyta blight at each planting dates. one of selected accessions was in all dates in common. Results show that among the studied accessions there are some adaptive accessions to the Entezary sowing and obtaining such suitable varieties of chickpea is possible.
