High-yielding variety

(Redirected from High-yielding varieties)
High-yielding varieties (HYVs) of agricultural crops are usually characterized by a combination of the following traits in contrast to the conventional varieties:
- higher crop yield per area (hectare)
- dwarfness
- improved response to fertilizers
- high reliance on irrigation and fertilizers - see intensive farming
- early maturation
Most important HYVs can be found among wheat, corn, soybean, rice, potato, and cotton.
HYVs become popular in the 1960s and play an important role in the green revolution, although their ancestral roots can be older.[1]
