Step 1: Understanding the Concept:
Plant propagation is the process of reproducing plants. Mangoes (*Mangifera indica*) are highly heterozygous and do not breed true from seeds.
To maintain desirable clonal characteristics, vegetative (asexual) propagation methods are used commercially.
Step 2: Detailed Explanation:
Let us analyze the vegetative propagation methods used for mangoes:
1. Inarching grafting: This is an older, traditional method of propagation. While labor-intensive, it is still used in some parts of India for highly reliable results.
2. Veneer grafting: This is a highly successful and widely adopted commercial method for propagating mangoes. It is easy to perform, achieves high success rates, and can be used on rootstocks of different ages.
3. Epicotyl grafting (also known as Stone grafting): This is a rapid commercial propagation method where young seedlings (10-15 days old) are grafted. It is highly successful in humid, tropical coastal climates like Konkan, Maharashtra.
4. Budding: While shield or patch budding can occasionally be performed on mangoes in experimental setups, it has extremely low success rates under field conditions due to latex exudation and graft incompatibility. As a result, budding is not a commercially viable method for mango propagation.
Step 3: Final Answer:
Budding is not a commercial propagation method for mango, corresponding to option (A).
