Seeds of mungbean varieties i.e. NCM-2013, Chackwal-Mung 06, NM-11 and AZRI-06 were selected for screening in saline soil. These miunngbean varieties were sown with normal as well as artificially salinity developed soil (ECe= 5.0 dSm-1 ) using completely randomized design with three repeats for screening purposes. The experiment was conducted during July to September, 2015 in the Head House of Land Resources Research Institute, National Agricultural research Centre, Islamabad, Pakistan. Data were collected on germination, plant height, root length, fresh / dry weight and chlorophyll contents during experiment period. Ionic concentrations of P, Cu, Fe, Mg and Zn were determined to compare the difference of edible quality in normal soil as well as saline soil Agronomic parameters like germination%, shoot height, root length, fresh weight/plant, dry weight/plant and chlorophyll content% were significantly affected by mungbean varieties under normal and saline conditions for screening purpose. Maximum germination (65% and 40%) was recorded under normal and saline soils r by NM-II and AZRI-06 mungbean varieties respectively. Shoot length was maximum (31.5 cm and 12.5 cm) by AZRI-06 and NM-II under normal and saline soil conditions respectively. Whereby root showed maximum lengths (16.5cm and 6.3 cm) by AZRI-06 and NM-II respectively. Fresh weight were the highest (7.6 g and 3.45 g) by AZRI-06 under both conditions. Dry weight was concerned it was the maximum (1.4 g and 0.6 g) by AZRI-06 and NCM-2013 under normal and saline conditions respectively. Maximum chlorophyll contents (34.6% and 25.1 %) were registered by AZRI-06 and NM-II under normal and saline conditions respectively. Maximum P% (0.13), Cu (5.01ppm), Fe (177.1ppm), Mg (1.99ppm) and Zn (158.8ppm) of Chakwal Mung-06 in normal soil and similar trend was also recorded in ionic concentration of P, Cu, Fe and Mg under saline soil. The saline soil affected the quality of mungbean showing the reduction under salt stress in ionic concentration. The results of ionic values showed that Chakwal Mung-06 attained the highest position following the AZRI-06.
