The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
This question focuses on the selection of rootstocks for commercial rose propagation.
The choice of rootstock depends on its ease of propagation from cuttings, root vigour, graft compatibility, and adaptability to regional soil and climatic conditions.
Step 2: Detailed Explanation:
Let us analyze the common rose rootstocks:
1. Rosa indica var. *odorata* (commonly known as 'Edouard' rose):
This is a highly vigorous, sturdy, and disease-resistant rootstock.
It is highly adapted to the hot, humid plains and tropical soil conditions of both North and South India.
It roots easily from cuttings and shows excellent graft compatibility with most hybrid tea, floribunda, and miniature rose varieties.
This makes it the most common and preferred rootstock for budding roses under South Indian conditions.
2. Rosa multiflora:
This is another popular rootstock, especially in temperate regions or hills, but it is less suited to the hot, clayey soils of the South Indian plains compared to *R. indica* var. *odorata*.
Thus, Option (B) is incorrect.
3. Rosa foetida, Rosa lucida:
These are wild species of historical or ornamental interest, but they are not used as commercial budding rootstocks in India.
Thus, Options (A) and (C) are incorrect.
Step 3: Final Answer:
The most common rose rootstock used under South Indian conditions is Rosa indica var. odorata.
This corresponds to Option (D).
