Aneuploidy and the origin of off-types in semidwarf wheat cultivars



Aneuploidy and the origin of off-types in semidwarf wheat cultivars



Indian Journal of Genetics & Plant Breeding 52(2): 153-155



The frequency of off-type plants observed among 111111; 136363 and 120000 plants in breeder seed plots of cvs Sonalika, IWP 722 and PBW 154 varied from 0.010 to 0.018%. Cytological analysis of 12 off-type progenies of each cultivar revealed that 50.0, 58.3 and 83.3% of progenies, respectively for cvs Sonalika, IWP 72 and PBW 154 were aneuploids. Thus aneuploidy contributed to 0.009, 0.006 and 0.008% for off-type plants.
