In Mizoram, Mulberry is generally propagated through:
A)
Saplings
B)
Cuttings
C)
Seeds
D)
All of these
In sericulture, specifically for Mulberry (Morus spp.) cultivation in Mizoram and across India, vegetative propagation is the preferred method.
1. Why 'Cuttings' is correct: Stem cuttings are the most common and efficient method of propagation. This ensures that the new plants are genetically identical (clones) to the parent plant, maintaining the high-yielding and high-quality leaf characteristics necessary for feeding silkworms. Cuttings establish faster and have a higher survival rate compared to seeds.
2. Why 'Seeds' is incorrect: Propagation by seeds is rarely used in commercial sericulture because it leads to high genetic variability (segregation), meaning the offspring may not possess the desirable leaf qualities of the parent plant.
3. Why 'Saplings' is incorrect: While saplings are the result of propagation, they are not the 'method' of propagation itself. One creates saplings *via* cuttings.
Therefore, for the promotion of Sericulture Extension Officers, the technical standard is that Mulberry is generally propagated through stem cuttings.
