Breeding of Vegetable, Spice and Tuber crops (2+1)

Hybrid varieties

• The development of hybrid varieties differs from hybridization and selection for superior individuals in the subsequent generation.
  
• The F1 hybrid of crosses between different genotypes is often much more vigorous than its parents.
  
• This hybrid vigour, or heterosis, can be manifested in many ways, including increased rate of growth, greater uniformity, earlier flowering, and increased yield, the last being of greatest importance in agriculture.
