A Study was conducted to investigate the relationship between seed vigour and field performance in chickpea. Two cultivars (Jam and Kaka), were used at two locations (The khalat-Pushan Laboratorial Centre and Research Station, Faculty of Agriculture, Tabriz University) in 1977. The seeds of two Cultivars were divided into three groups from which one group was considered as the non-deteriorated or Control (VI) and the other two groups were artificially deteriorated by the rapid aging test, at 40 °C, for 15 and 20 days respectively (V2,V3). Therefore, there were three various vigour levels for each cultivar, (V 1,V2, V3). Electrical conductivity of leaked material form seeds, percentage of the viable seeds, percentage of the normal seedlings, speed of germination, and average dry weight of the seedlings were measured for each seed mass. For field study, seeds were sown in a split-plot experiment factorial with R.C.B design, in three replications and percentage and speed of the seedling emrege were measured. During growth season, the other traits were measured, as: percentage of green cover, time to flowering, time to maturity, harvest index, yield components and final yield. Results showed that in all laboratorial traits, vigourous seeds (VI) had significantly better, performance than deteriorated seeds (V2,V3). Correlation between studied traits, showed that among the seed vigour tests, electrical conductivity test and the speed of germination were significantly correlated with seed yield. Therefore seed vigour tests, have a considerable ability for prediction of chickpea performance.
