Zhagin (1995), found that bulbous- leaf and reduced-leaf mutants, which is
obtained by treating winter wheat varieties by chemicals, were temperature sensitive.
The reduced-leaf mutants were adaptive to low-temperatures (8-15o
C), whereas, the
bulbous-leaf mutants adapted better to high temperatures (18-20o
C). Sartaer, (1991)
found that chemical mutagens and pesticides produced shorter-strawed, compacted
ears , awned , semi-awned , early maturing , late-maturing and resistant to rust
resistant to rust mutant lines in the M2 and M3 generation ,. Induced mutation in
hexaploid wheat by treating seeds with ethylmerthane Sulfonate (EMS) produced
mutant lines with resistance to 13 races of stem rust out of 15 races (Williams et al.,
1992).
