Effect of Imazethapyr herbicide (Pursuit) on Germination indices of Kabuli and Desi chickpea (Cicer arietinum L.) cultivars under vitro condition

This study was performed to evaluate and compare the reaction of Desi and Kabuli type chickpea cultivars under the influence of Imazethapyr herbicide (Pursuit) in vitro. Cultivar agents in 4 levels Pirooz (T1), Bivanich (T2), Adel (T3) and Kaka (T4) and Imazethapyr herbicide in 6 levels 0.25 (C1), 0.5 (C2), 0.75 (C3), 1 (C4), 1.5 (C5) and distilled water as a control treatment (C6) were examined in factorial designs in a completely randomized design with three replications in the research laboratory of the Faculty of Agriculture, Islamic Azad University, Sanandaj Branch. The results of analysis of variance showed that the interaction of cultivar and herbicide was significant for the traits of greatest root length and tolerance index. The highest tolerance index was observed in the control treatment (distilled water) (0 ppm) and the lowest in the dose treatment of 1.5 ppm (C5). Desi type of Kaka and Pirooz cultivars had the highest tolerance index compared to Bivanich and Adel Kabuli type of chickpea cultivars. The effect of intermediate doses of Imazethapyr herbicide on germination indices were no significant.
