The effect of NaCl on the growth, yield, and ion uptake of nine cultivars of Vigna mungo L. (blackgram), AARIM 35, AARIM 46, AARIM 50, Mash 48, Mash 59, Mash 216, Mash 654, Mash 891, and Qandhari mash was assessed in a pot experiment. Different cultivars showed differing responses to NaCl salinity. At 40 meq 1 −1 NaCl cvs AARIM 50, Mash 891, and Qandhari mash had significantly greater mean leaf area compared with the other cultivars. Cultivars did not differ significantly in chlorophyll content at the salt treatment. The high leaf area producing cultivars AARIM 50, Mash 891, and Qandhari mash contained relatively high amount of Na+ in both shoots and roots indicating the typical halophytic nature. The leaf osmotic potential was relatively lower in AARIM 50 and Mash 891 and high in Qandhari mash at the salt treatment. Cvs AARIM 35, Mash 216, Qandhari mash had greater seed number per plant, 1000 seed weight, and seed yield, although the former two had lower leaf area, whereas cvs AARIM 46, AARIM 50, and Mash 891 showed intermediate performance for yield parameters but had relatively greater leaf area. Cvs Mash 48, Mash 59, and Mash 654 did not survive till seed setting at 40 meq 1 −1 NaCl. The protein content of Qandhari mash decreased significantly compared with the other cultivars at the salt treatment. The presence of considerable amount of inter‐cultivar variability in blackgram showed that advancement in improvement of salt tolerance in blackgram is highly possible.
