Development of blast resistant versions of improved samba Mahsuri variety of rice (Oryza sativa L.) through marker assisted breeding

Abstract

The present research work was carried out in some villages of Sirsa district of Haryana (India) to assess the ground water quality and also check its suitability for irrigation purpose. A total of 15 ground water samples were taken from different locations in both the pre and post monsoon period of 2017. On the basis of chemical analysis, the variation is the mean concentration of cations and that of the anions were observed as Nat+>Mg2+ >Ca2+>K+ and Cl->HCO3->SO42->CO32- respectively in both pre and post monsoon time. The results of the physico chemical study of ground water were compared with the Indian standards and WHO Standards. Several parameters like potential soil salinity (PSS), permeability index (PI), Sodium absorption ratio (SAR), Chloro alkaline Indices (CAI-I and CAI-II), Gibb’s ratio (GR.I and G.R.II), Sodium percentage (%Na), Soluble Sodium percentage (SSP), Residual Sodium carbonate (RSC), meteoric genesis (Met. Gen.), Base exchange, Magnesium Hazard, Kelly’s ration (KI) were measured to check the suitability for irrigation.
