The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
This question focuses on the varietal characteristics and disease resistance traits of commercial pineapple (*Ananas comosus*) cultivars.
Step 2: Detailed Explanation:
Let us evaluate the characteristics of the main pineapple cultivars:
1. Smooth Cayenne:
This is the most widely grown commercial pineapple cultivar in the world, accounting for over 70% of global production.
Its leaves are mostly spineless (smooth), containing only a few small spines near the tip.
This spineless trait makes harvesting and field maintenance much easier.
It is also known for its resistance to gummosis, a disease caused by the fungus *Phytophthora* or other pathogens that leads to gummy exudations on the fruit and stem.
Thus, it matches the description.
2. Queen:
This cultivar is known for its sweet, crisp, and deep-yellow flesh.
However, its leaves are highly spiny, and it is susceptible to several pathogens.
Thus, Option (B) is incorrect.
3. Spanish cultivars (such as Red Spanish):
These are sturdy plants with highly spiny leaves, grown primarily for their resistance to shipping damage, but they are not spineless.
Thus, Option (C) is incorrect.
4. Abacaxi:
This is a spiny cultivar popular in Brazil, known for its sweet, white flesh, but it is not a smooth-leaved commercial standard.
Thus, Option (D) is incorrect.
Step 3: Final Answer:
The pineapple cultivar characterized by spineless leaves and resistance to gummosis is Smooth Cayenne.
This corresponds to Option (A).
