Initially screening for salt tolerance species were carried out and the scientists identified one salt tolerant variety of cotton (NIAB-999) and one salt tolerant variety of wheat (Sarsabz) for salt-affected areas. Two salt tolerant mutants, one each of mungbean & cowpea were developed and an early maturing cowpea mutant line was also identified that can tolerate salinity up to EC = 10 dS m.
