This research was conducted at Abu Jerash farm, Faculty of Agriculture,
Damascus University during 2011/2012 season to assess the effect of different
doses and concentrations of physical and chemical mutagens on some
quantitative and qualitative t
raits in the second generation (M2) of two
varieties of durum wheat.
Results showed significant differences (p<0.05) between the varieties,
treatments and the mutual interactions. Bowhoth 9 was superior in the average
of total number of changes (16.59%) compared with Doma1 (13.29%). The
total number of qualitative changes in the varieties studied was 14 types of
change, alternated and varied in appearance with the different doses and
concentrations of mutagens used. Bowhoth9 was superior in the average of
grain`s number (238.84), grains weight (11.89g) and the one thousand grain`s
weight (58.35g) in comparison with the parallel counterparts of averages
174.31, 7.06g, 54.38g, respectively in Doma1.
