High-yielding variety

High-yielding varieties (HYVs) of agricultural crops are varieties of crops that are usually characterized by a combination of the following traits in contrast to the conventional varieties:

• Higher crop yield per unit area
• Dwarfness
• Improved response to fertilizers
• High reliance on irrigation and fertilizers - see intensive farming
• Early maturation
• Resistance to many diseases
• Higher quality of crops.

The most popular HYVs can be found among wheat, corn, soybean, rice, potato, and cotton. They are heavily used in commercial and plantation farms.

The Green Revolution in the late 1960s introduced farmers to cultivation of grains using high yielding varieties (HYVs) of seeds, although their ancestral roots may be older.

Compared to the traditional seeds, HYV seeds promise to produce much greater amounts of grain on a single plant. As a result, the same piece of land now produces far larger quantities of foodgrains than was possible earlier. HYV seeds, however, need plenty of water and also chemical fertilizers and pesticides to produce best results.

HYVs are developed in the field of biotechnology.
