Flint corn is botanically written as
Show Hint
- Zea mays var. indentata
- Zea mays var. indurata
- Zea mays var. ceratina
- Zea mays var. tunicata
The Correct Option is B
Solution and Explanation
E. Lewis Sturtevant classified maize into distinct botanical varieties based on endosperm starch composition and kernel structure.
Step 2: Detailed Explanation:
The botanical varietal classification of maize (Zea mays L.) is:
1. Flint corn: Zea mays var. indurata (hard, vitreous endosperm surrounding small starchy center).
2. Dent corn: Zea mays var. indentata (crown indentation from starch shrinkage).
3. Waxy corn: Zea mays var. ceratina (100% amylopectin).
4. Pod corn: Zea mays var. tunicata (each kernel enclosed in a floral glume).
5. Sweet corn: Zea mays var. saccharata.
6. Popcorn: Zea mays var. everta.
Step 3: Final Answer:
Hence, flint corn is botanically written as Zea mays var. indurata.
