Step 1: Understanding the Concept:
Pear (Pyrus communis) is an important temperate fruit crop grown in the high-altitude zones of Himachal Pradesh.
Cultivars are classified based on their ripening and harvesting window into early, mid-season, and late-season varieties.
Step 2: Detailed Explanation:
Let us review the harvesting season of the listed pear cultivars:
A. Bartlett (William's Bartlett): This is the most popular, high-quality commercial cultivar. It matures during July-August, making it a classic mid-season variety.
B. Starkrimson: This is a red-colored pear mutation (budsport) that matures in late July to mid-August, placing it in the mid-season category.
C. Flemish Beauty: It is a highly productive, sweet variety that matures during August, classified as a mid-season cultivar.
D. Conference: This is a late-season cultivar that matures in September. It requires a longer growing season and is harvested after mid-season varieties are finished.
Therefore, the mid-season pear cultivars are Bartlett (A), Starkrimson (B), and Flemish Beauty (C).
Step 3: Final Answer:
Since A, B, and C are mid-season cultivars while D is late-season, the correct choice is (B).
