168 April for Tal Abaid (36*42'N, 38°57'E and 355 m altitude), at a frequency of at least once in every 13 years. Since the winter-planted crop at such a period would generally be actively photosynthesizing and making rapid growth, owing to a favorable radiation level and thermal and moisture regimes, a sudden exposure to frost could have a very serious consequence for the crop. To ensure the future success of winter planting of chickpeas in the lowland Mediterranean" region, it is necessary to develop cultivars that have tolerance not only to ascochyta blight but also to cold (T,
