Question

Scientific name of flint maize is:

• A. Zea mays indentata
• B. Zea mays indurata
• C. Zea mays saccharata
• D. Zea mays everta

Hint:

In India, the most commonly cultivated maize type is Flint Maize ($indurata$), whereas in the USA, Dent Maize ($indentata$) dominates the production.

Answer 1

The Correct Option is B

Concept: Maize (Zea mays) is classified into several types based on the characteristics of the endosperm in the kernel.

Step 1: Define Flint Maize.
Flint maize (Zea mays indurata) has a kernel composed mainly of hard, vitreous (glass-like) starch that surrounds a small soft starchy center. The outer layer is very hard, resembling "flint." It is widely grown in India and Europe due to its ability to germinate in cooler, wetter soils compared to dent maize.

Step 2: Identify other subspecies.
* Zea mays indentata: Dent Maize (characterized by a depression or "dent" at the top of the kernel). * Zea mays saccharata: Sweet Corn (high sugar content, used for fresh consumption). * Zea mays everta: Popcorn (extreme form of flint with very thick pericarp).

Step 3: Confirm the match.
The term *indurata* comes from the Latin word for "hardened," which perfectly describes the flint maize kernel.
