“…Similar observations have also been reported by Gaul et al (1966). The gibberellic acid present in the plant might have reduced the aberration in EMS treated plant which in turn could have reduced the pollen sterility and therefore, cent per cent pollen fertility could be observed at low concentration (Narsinghani and Kumar 1971).…”

Mutation can be beneficially utilized for tailoring crop plants. Chemical mutagen become one of important tools in crop improvement. Each mutagen has its important role as positive or negative effects on crops. Cytological abnormalities during meiosis has also been regarded one of the dependable parameters for estimating mutagenic sensitivity of a species. Studies undertaken in M 1 and M 2 generations on pink flower and white flower strains of Catharanthus roseus showed EMS elicit various chromosomal aberration in meiosis. Different types of meiotic abnormalities such as fragments, univalents, stickiness and unorientation of bivalents could be observed at metaphase I and bridges, laggards, unequal separation, unorientation of bivalents and stickiness could be seen at anaphase I. Meiotic abnormalities increased along with the increase in concentration in mutagens. The percentage of meiotic abnormalities was recorded maximum in M 1 generation as compared to M 2 generation. Contrary to pink, white flower strain exhibited maximum meiotic abnormalities and pollen sterility and hence, more sensitive to EMS. The highest pollen fertility was recorded in 0.2% concentration of EMS in pink flower strain of C. roseus.
