In view of availability of new and diverse types of cytoplasmic male sterile (CMS) lines in Indian mustard there is a need to standardize its seed production in field conditions. Planting ratio between the parental lines is important for optimizing the female parent /hybrid seed production. Experiments were conducted with seven diverse CMS lines with a single pollen parent in different planting ratios. The seed yield in various rows from the pollen parent indicated that rows nearer to the pollen parent yielded higher quantity of seeds than that in distantly located rows. Further, the most promising CMS lines, namely, moricandia and ogura, produced higher quantity of seeds in 8:2 (female: male) and 16:2 planting ratio, respectively.
