Causes:
ADVERTISEMENTS:
1. Change in chromosome number/ structure.
2. Gene mutation.
3. Plasmagene mutation.
4. Attention in gene expression.
ADVERTISEMENTS:
5. Gene amplification.
6. Mitotic and erasing over.
7. Rearrangements in Cytoplsamic genes.
Applications:
ADVERTISEMENTS:
1. Resistant to disease variants can be isolated.
2. Stress Resistance.
3. Low-temperature mutant.
4. Mutants for Agronomic traits.
5. Mutants for Efficient Nutrient Utilization. Achivements
1. ‘Scarlet’ variety in sweet potato.
2. Sigma – Alfalfa.
Advantages:
1. High frequency mutagensis.
2. Variation is created.
3. Novelity.
4. Less time for variety release.
Limitations:
1. Selected cell lines fail to regenerate.
2. Many of the selected clones are unstable.
