V. Padmajaa@gmail.com<p>Tuberose (<em>Polianthes tuberosa</em> Linn.) is one of the most important flower crops grown under the tropical and subtropical conditions in India. The crop is affected by leaf spot disease caused by <em>Alternaria polianthi</em>, which significantly impacts its growth and flower yield. The disease is prevalent in both single and double varieties, especially in the regions with high rainfall and humidity. A study was conducted with gamma ray irradiated bulbs using 44 variants of mutant population with one untreated bulb (Control). Among the variants of mutant population studied in the VM<sub>2</sub> generation, mutant M<sub>333</sub> exhibited significantly highest per cent disease index (susceptible) compared to untreated control. No incidence of disease was noticed with mutants<em> viz.,</em> M<sub>473C</sub>, M<sub>178</sub> and M<sub>21,</sub> hence these were characterized as immune mutants to the leaf spot disease caused by <em>Alternaria polianthi</em>.</p>2026-01-03T00:00:00+00:00Copyright (c) 2026
