Which among the followings is not the characteristic of the durum wheat?
EXPLANATION
Crop Ecology: Ecological Optima, Environmental Limits, Crop Geography & Agro-Ecological Delineation
- Durum Wheat Leaf Morphology (Option 1): Durum wheat (Triticum durum, tetraploid $2n=28$, AABB) leaves are characteristically broader, stiffer, more erect, and darker green compared to common bread wheat (Triticum aestivum, hexaploid $2n=42$, AABBDD). The assertion that durum leaves are narrower is incorrect, making it the right answer.
- Grain Hardness & Weight (Option 2): Durum wheat grains are flinty, extremely hard, vitreous, and possess higher test weight and thousand-kernel weight than bread wheat.
- Grain Size (Option 3): Durum kernels are typically larger and more elongated than common hexaploid wheat kernels.
- Dough Elasticity (Option 4): Durum wheat gluten has high tenacity but low extensibility and elasticity, making it ideal for pasta, semolina (sooji), and macaroni rather than leavened loaf bread. (Correct answer: Option 1)
