The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Many apple (Malus domestica) cultivars, particularly those in the "Delicious" group (like 'Red Delicious' and its mutations), are self-unfruitful and cross-incompatible with closely related sports.
To obtain a commercial fruit set, orchards must be interplanted with compatible, heavy pollen-producing "pollinizer" cultivars that bloom at the same time.
Step 2: Detailed Explanation:
The cultivar 'Golden Delicious' is globally recognized as the most effective universal pollinizer for the Delicious groups of apples.
- It produces an abundance of highly viable, compatible pollen.
- Its flowering period overlaps perfectly with the bloom period of 'Red Delicious' and its bud sports.
- It is highly attractive to insect pollinators (bees).
Let us evaluate the other options:
- 'Jonathan': It is a good pollinizer, but its bloom overlap with all Delicious mutations is less consistent compared to 'Golden Delicious'.
- 'Jona Gold': It is a triploid cultivar ($3n$). Triploid apples produce sterile, non-viable pollen and cannot serve as pollinizers.
- 'Greensleeves': It is a green apple cultivar, but not widely used or recommended as a primary pollinizer for the Delicious group.
Therefore, 'Golden Delicious' is the correct answer.
Step 3: Final Answer:
The apple cultivar that serves as an excellent pollinizer for the delicious group is Golden Delicious.
