Speed Breeding: To Expedite Research and Breeding in Rice
Keywords:
Speed Breeding, Rice, Photoperiod.Abstract
To meet the growing population’s food requirements, speed breeding could be the most appropriate strategy to develop improved cultivars with high yield potential, and it can enhance research in agriculture by reducing the generation time. However, the strategy involves a costly setup and is quite expensive. In hilly and temperate regions of India, only one crop can be taken in the monsoon season, as the temperature drops in October, it restricts breeding advancement. In rice, with the manipulation of photoperiod requirements in controlled conditions inside a polyhouse, three to four crops can be taken within a single year, which will speed up cultivar development.Downloads
