Question:
Which of the following vegetable crop has brown anther type and petaloid type male sterility?
Which of the following vegetable crop has brown anther type and petaloid type male sterility?
Show Hint
Petaloid male sterility is highly stable and preferred in carrot hybrid seed production because it prevents any chance of accidental self-pollination.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Male sterility is a key tool in hybrid seed production that eliminates the need for manual emasculation. In cytoplasmic-genetic male sterility (CGMS), different morphological expressions of sterility occur depending on the interaction between mitochondrial and nuclear genes.
Step 2: Detailed Explanation:
In carrot (Daucus carota L.), two main types of cytoplasmic male sterility are exploited for hybrid seed production:
Brown Anther Type: The stamens develop normally, but the anthers turn brown, shrivel, and fail to produce viable pollen before anthesis.
Petaloid Type: A homeotic mutation occurs where the five stamens are physically replaced by five petal-like structures, making the flowers completely pollen-free.
These two distinct forms of male sterility are characteristic features used in carrot breeding.
Step 3: Final Answer:
The crop is Carrot.
