Our data provides useful information for investigating the function of the OsMsh6 gene in DNA repair and exploiting MMR mutants in induced mutation
breeding in rice.
has the potential to become an important part of the solution to the world's food crisis.

method has been successfully used to increase the quality, disease, pest resistance and ultimately the yield in many crops including potato (Ahloowalia 1990); Sonnino et al.
Present results confirm that induced mutations
are contributing significantly to creating genetic variations in crop plants.
(2001) induced mutation
has great potentials and serves as a complementary approach in genetic improvement of crops.
ABASIN-95 by induced mutation

The goal is to use hybridization and induced mutation
breeding to produce high-yielding indica lines with good-quality grain and ideal amylose content for the U.S.
Georgia-02C originated from a cross made in 1993 between 'Southern Runner' (Gorbet et al., 1987) and a Georgia high-oleic selection derived by [gamma]-irradiation induced mutation
from seed of 'Georgia Runner' (Branch, 1991).

Thus in the present study the important desirable characters, which had been achieved through induced mutation
include high yield, grain quality, early maturity, disease resistance, improved plant type and better protein, oil and fatty acids.

Therefore, artificial mutagenesis through irradiation or by use of different chemicals has become a very significant way for plant propagation in flower reproduction (Barakat and El-Sammak, 2011).Through induced mutation
, a large number of plant varieties have been developed with improved traits such as high yield, early maturity, as well as high protein content, biotic and abiotic resistance.
The highest observed induced mutation
frequency for all three Salmonella strains occurred at a daunomycin concentration of 120 [micro]g/mL (maximally induced mutation
frequencies are listed in Table 2, Column 3).
