Two varieties of cotton (cv. MCU 5 and MCU 11) were treated with gamma rays, ethyl methane sulphonate and sodium azide with the objective of determining the most efficient mutagens and most responsive genotype for induction of mutations affecting predominantly reproductive parts. Frequency and spectrum of mutations affecting floral traits was computed on M2 plant population that was screened for variations in chlorophyll, flower colour and floral parts. Among the floral variations, elongated petals, colour changes and reduced petals were the dominant ones. The differences in mutations observed in the two cultivars have been attributed to the variations in the microgenomic architecture
