摘要：
The present work was carried out to study the effect of Ethyl Methane Sulphonate (EMS) treatment on microsporogenesis and pollen fertility in Coriandrum sativum L. For this purpose, the seeds were treated with three serial doses of EMS viz. 0.1, 0.3 and 0.5% and sown in triplicate to raise the M-1 generation. Control was also maintained separately for each set. During the investigation of different meiotic phases, PMCs with desynaptic chromosomes were observed in plants treated with 0.3 and 0.5% solutions of EMS. Besides the desynaptic univalent chromosome, other various types of chromosomal aberration were also observed in different phases of meiosis such as laggards, unequal separation and bridges with abnormal post meiotic products.
