Conclusion

The study revealed important variation among onion genotypes in their response to purple blotch disease caused by Alternaria porri. A subset of genotypes, namely Arka Kalyan (12.80 %), 1783 (13.73 %), 1774 (17.87 %), Bhima Red (19.47 %), Bhima Kiran (20.20 %) and Bhima Shakti (20.73 %) stood out by showing the lowest levels of disease incidence. Conversely, genotypes such as W-507 (63.93 %) registered as the highest disease incidence.
