| Description |
Artemisia pallens Bess. is a low volume and high value essential oil plant used in perfumery, cosmetic and flavouring industries. On account of the failure of conventional procedures to induce variability in species, mutation techniques have been tried in our experiments. Dry
and viable seeds (moisture content 8%) of homozygous pure breeding lines were subjected to 150–500 Gy doses of gamma rays and 0.01–0.1% ethyl methane sulphonate (EMS) for
8 h. Desirable qualitative mutants were recovered from segregating M2 generation (4,283 plants scored) raised as single plant progenies. The spectrum of morphological mutants included late and early flowering types; bushy and high yielding types; tall and more capitula-producing types and high oil and high davanone yielding types. These
were raised through M3 families to evaluate stability
and transmission of mutant characters. As such out of 15 different types selected in M2, only 11 types bred true to their characteristic variability. Based on their performance, the mutants were characterised depending upon their distinguishing features. Davanone, the main component
of oil showed the maximum increase (64.22% against 54.64% in control) in mutant ‘S–5’ recovered from exposure with 250 Gy c-rays. Mutant ‘E-6’ was economically most viable
having increased oil biosynthesis (0.36% against 0.22% in control) and hence yields higher oil per unit area than the parental control (isolated from 0.05% EMS treatment).
