Abstract

Seeds of (Oryza sativa L.) cultivars CSAR-13, CSAR-27, CSAR-77, CSAR-148-205, CSAR-253,
CSAR-256, Pant-12, Basmati-370, IET-11120 and IR-539-30-2-2-3-3 were subjected to water stress
in terms of various external water potential during seed germination and seedling growth under
osmoticum solution of PEG-6000. The cumulative germination and seedling growth decreased
significantly with increasing intensity of stress irrespective of cultivar tested. However, CSAR-13,
CSAR-77 and CSAR-27 showed higher tolerance to decreasing water potential with respect to
germination, while IET-11120 and IR-539-30-2-2-3-3 proved better for seedling growth under moisture
stress condition.
