Abstract

Salinity is one of the major environmental factors affecting the crop production of wheat (Triticum aestivum L.) worldwide. Screening of varieties with tolerance to salt stress is important for future breeding problems. Current study was focused on two aspects; damage during cell division due to stress and on peroxidase activity to determine the coping capability of the varieties. Mitotic index of most varieties under study was decreased because of the cell damage but two varieties Abadgar-93 (treatment 2.46%, control 4.21%) and Kiran-95 (treatment 2.20%, control 3.05%) showed less decrease and similarly these varieties showed less peroxidases activity indicating more tolerance to the saline condition. Wheat varieties from Sindh, Pakistan showed potential for breeding programs and needed to be screened more thoroughly for their quality, yield potential and tolerance towards abiotic stresses.
