Standardization of a screening technique for salinity tOlerance' in groundnut (Arachis hypogaea L.) and pigeonpea (Cajanus cajan L.)

Salinity affects plant growth, development and yield In approximately 100 M ha of arable land worldwide. Besides, various management options available the Introduction of salinity tolerant varieties In such areas could partly ease the Increasing global food demand. Here, six groundnut (ICG (FDRS) 10, ICGS 44, ICGS ICGV 86031, JL 24, and TAG 24) and pigeonpea (ICPL 88039, ICPL 88034, ICPL 87119, ICPL 96058,ICP 7035 and ICPL 366) genotypes were screened by conducting two experiments In soli treated with five different NaCI (mM) concentrations (0, 50, 100, 125, 150) and (0,50, 75, 100, 150) respectively for groundnut and Pigeonpea, under controlled conditions. Salt concentrations of 100-125 mM were found to be critical to screen groundnut genotypes whereas 75 mM NaCI appeared most suited treatmen
