3 Induced Mutagenesis: Biophysiological Damages and Cytological Abberrations
3.1 Bio-Physiological Damages
The variations in terms of bio-physiological damages, gene mutations and chromosome mutations induced by mutagens in any mutation breeding programme have been used as criteria in determining the mechanism of action of the mutagen in question and also the sensitivity of the biological material towards the mutagenic treatments. Among the variations caused, gene and chromosomal mutations may be transferred from M1 to the subsequent generations, whereas, biological and physiological damages are generally restricted to the M1 generation.
It is possible to identify plants, which suffer maximum damage due to mutagenic treatment using different ...
