Development of high yielding aromatic mutants of rice (Oryza sativa L.) from a local aromatic cultivar, Tulaipanji by using gama radiation

Published on

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 (>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.
