Abstract
Mutation induced variability is an important method in plant breeding to create non-existing desirable genotype(s) for crop improvement. In this endeavour, gamma radiation was used to create variability for improving plant type and yield attributing traits in a local aromatic cultivar, Tulaipanji. Eight desirable mutants were identified from M4 generation. All those eight mutants induced from Tulpanji were photoperiod-insensitive, non-lodging, semi-dwarf with high yield potential and retained the aroma. Mutants TP3-2, TP3- 4 and TP3-6 showed high increase in yield (greater than 89%) over the control cultivar, Tulpanji. As the mutants were photoperiod insensitive, they may be recommended for cultivation for both boro and kharif seasons after necessary trials and demonstrations.
