Field and loboratory experiments conducted during kharif and rabi and summer seasons of 1990 to study the influence of seasons on seed quality parameters on three open  pollinated varieties viz,. 'SS-56', Morden and 'EC-68415', showed that seeds produced during rabi and summer had higher germination per cent (94.5% and 95.3%, respectively), maximum shoot and root length (21.38 and 22.64, 20.54 and 21.84 cm, respectively), higher speed of germination (21,83 and 20.92, respectively) greater vigour Index (4156 and 3985, respectively) and lower Electrical condictivity (685 and 776 dslm respectively). The cultivar EC-68415 recorded maximum shoot and root length (22.03 and 23.11 cm, respectively), seedling growth rate (29.85 mg), speed of germination (22.42), vigour index (4137) and less EC (713 ds-lm ) as compared to other cultivars, whereas germination percentage was higher with Morden (96%) followed by EC-68415 (92.4%) and SS-56 (86.9%), The interaction effects were found significant for seed germination and vigour index only.
