Correct answer: A. Crossing of two inbred parental lines
- A. Crossing of two inbred parental lines
- B. Harvesting seeds from the most productive plants
- C. Inducing mutations
- D. Bombarding the seeds with DNA.
Explanation
Hybridisation or heterosis or hybrid vigour is defined as the superiority of hybrid over parents. It has been commercially exploited in different commercial crops like maize, sorghum, bajra, etc. The main steps include: selection of parents, selfing of parents, emasculation, bagging, crossing of desired and selected parents and finally seed setting and harvesting.
