| Abstract: | Genotyptc differences in wheat were observed in cell membrane with respect to injury caused by osmotic shock created with 40 per cent polyethylene glycol-6000. In general, genotypes with high cell membrane injury also registered much reduction in leaf water potential and osmotic potential. Cell membrane injury measured at 25 days after germination was found to be related with genotypic performance under drought conditions in field. Cell membrane stability measurements of normal plants, even at a very early stage of growth, is reported as criteria for selecting drought tolerant wheat genotypes. |
