What are the advantages and disadvantages of hybrid rice mentioned by Yuan Longping?

Advantages: The significance of hybrid rice lies in solving the problem of world population and food shortage. Because hybrid rice has higher yield, disease resistance and various comprehensive forms than non-hybrid rice, it means that the grain yield of hybrid rice has increased, which has solved the grain problem for the increasing population and limited land. Disadvantages: because of artificial hybridization, whether long-term consumption will have an impact on the human body is not clear, just like genetically modified food!
