Study Notes
- Mutagenesis is a functional branch of modern plant breeding.
- Mutations can be induced in any phase of development and affect all properties and characters of plants.
- Mutations can be subepidermal or epidermal and affect somatic or gamete cells.
- Induced mutations have a high frequency, but a low percentage of positive forms used in breeding.
- Mutations affect more quantitative characters controlled by major genes.
- Mutants of agronomic interest are not easy to obtain and require a large amount of work.
- Mutations can be used to obtain disease resistance in crops.
- Mutants are of real perspective in improving plants with vegetative propagation.
- Mutagens produce a complex mixture of mutations and non-genetic aberrations.
- Desired mutants are rare and must be isolated using appropriate methods.
