A) Advantages :
- Varieties are stable and easy to maintain
- Avoids inbreeding depression
- Clonal selection, combined with hybridization generates necessary variability for several selections.
- Only method to improve clonal crops
- Hybrid vigor is easily utilized selection may be used in maintaining the purity of clones.
- Selection utilizes the natural variability already present in the population.
- Sexual reproduction is necessary for creation of variability through hybridization.
- Applicable only to the vegetatively propagative crops.
