What is the botanical name of six-row barley?

✅Explanation: Hordeum vulgare is the botanical name for six-row barley. This type of barley has six rows of grains on its spike and is commonly used in animal feed, brewing, and certain food products.

📌Other Options Explanations:
-(b) Hordeum distichon: This is the botanical name for two-row barley, which has two rows of grains and is preferred for malting and brewing high-quality beers due to its lower protein and higher starch content.

🛑 Additional Information::

• Characteristics of Hordeum vulgare (Six-Rowed Barley):

• Number of Rows:
-Produces six rows of kernels on the spike.

• Grain Yield:
-Typically has higher grain yield compared to two-row barley due to the increased number of kernels per spike.

• Protein Content:
-Higher protein content, making it suitable for animal feed but less ideal for malting quality in beer production.

• Enzyme Activity:
-Contains higher enzyme activity, beneficial for brewing processes that require this characteristic.

• Adaptability:
-Well-suited for a variety of climates and soils, showing good adaptability.

• Spike Structure:
-The spike has fertile florets in all three spikelets of each rachis node, leading to six rows of grains.

• Uses:
-Primarily used for animal feed, brewing (especially for enzyme-rich malt), and occasionally for human consumption in food products.

• Geographic Distribution:
-Widely grown across the world, especially in regions where six-row barley is preferred for livestock feed or industrial uses.

• Straw Quality:
-Straw is often used as fodder for livestock due to its higher volume and decent nutritional value.

• Resistance:
-Tends to have moderate resistance to some diseases, although specific susceptibility depends on the variety.
