Meiotic behaviour of plant chromosomes is influenced by both genetic and environmental factors. The present paper shows the affect of abnormal meiosis on pollen fertility. Meiotic restitution is considered to be a common mechanism of polyploidization in plants and hence is one of the most important processes in plant speciation. Pollen mother cells (PMCs) of diploid potato from anthers at different stages of meiotic process were analyzed for their chromosomal behaviour and irregularities. Pollen morphology was also studied through SEM as it is significantly helpful at the generic and specific level. Various meiotic irregularities were observed: univalent and multivalent formation, chromosome bridges, fragments, lagging chromosomes etc. B-chromosome was first time reported in wild diploid potato, though the frequency of the same was less. Specie was identified as Solanum chacoense.
