For modern and industrialized horticulture, there
is always a demand and necessity for new cultivars.
Induced mutations have played an important role in
the improvement of plants, and more than 3200 mutant
cultivars have been developed through this approach
(Pierre, 2012). Modern day plant breeding is based on
creating variations followed by selection, evaluation,
and multiplication of the desired genotypes. In a crop
improvement program, plant breeders often combine
several techniques in order to increase efficiency and
reduce the time needed for the development of a new
cultivar. Plant breeders combine tissue culture technique
for rapid multiplication of regenerants, mutation induction
to enhance variations, and molecular marker methods to
detect the genetic variation (Ahloowalia and Maluszynski,
2001). Such a combination of techniques has been
exploited for the creation of new and novel plant cultivars,
particularly in vegetatively propagated species (Broertjes
and Van Harten, 1988; Pinet-Leblay et al., 199...
