Two chemical mutagens, namely, pyrogallol and pyrocatechol were employed to induce variability in some of the production traits in sugarcane such as the number of internodes, girth of the internode and brix per cent. Two concentrations under each mutagen were used and their effects were compared with the control in the νM generation. The results indicated the absence of gross morphological changes, but induction of a wide spectrum of variability very characteristic of polygenic mutations. The mutagenic effects were positive in the case of number of internodes and brix content and negative in respect of girth. Very high transgressive variants on the positive side were obtained and selected for further studies. Consequent to the induction of micromutations through chemical mutagenesis, the scope for improvement of sugar per acre seems promising. [ABSTRACT FROM AUTHOR] |
