In Mizoram, mulberry is generally propagated through:

A) Seedling
B) Cutting
C) Sapling
D) Layering
Mulberry (Morus spp.) is primarily propagated vegetatively to ensure that the offspring maintain the exact genetic characteristics of the parent plant, particularly for high-leaf-yield varieties used in sericulture. In Mizoram and other sericulture-growing regions, 'Stem Cuttings' are the most common and commercially viable method of propagation. 1. Why 'Cutting' is correct: Stem cuttings (usually 15-20 cm long) are planted during the rainy season. This method is faster, ensures uniformity in the plantation, and provides a higher success rate compared to seeds. 2. Why 'Seedling' is incorrect: Propagation by seeds often leads to high genetic variability, meaning the resulting plants may not produce the high-quality leaves required for silkworms. 3. Why 'Sapling' is incorrect: A sapling is a young tree; it is the result of propagation, not the method of propagation itself. 4. Why 'Layering' is incorrect: While layering is biologically possible for mulberry, it is labor-intensive and impractical for large-scale commercial plantation establishment in the hilly terrain of Mizoram.
