Combination of Somaclonal Variation and Mutagenesis for Crop Improvement

Endang G. Lestari

Abstract


Mutation-based
plant improvement, which changes one or a few specific
traits of a cultivar, can contribute to crop improvement.
Tissue culture increases the efficiency of mutagenic
treatment to induce variations. In vitro culture in
combination with induced mutation can speed up the
breeding program by generating variability, followed by
selection and multiplication of the desired genotypes. In
many vegetative propagated crops, mutation induction in
combination with in vitro culture techniques can be the
most effective method for plant improvement. In seed
propagated species, the application of mutation coupled
with doubled haploid systems seems to be highly promising
in crop improvement. This approach speeds up the breeding
program through generation of variability followed by
selection of homozygousity and rapid multiplication of
desired genotypes.


Keywords
