35、 Longping realised that larger fields were not the solution.Instead,farmers needed to boost yields in the fields they had.How this could be done was a challenging question at the time.Yuan was convinced that the answer could be found in the creation of hybrid rice.A hybrid is a cross between two or

36、more varieties of a.One characteristic of hybrids is that they usually attain a higher yield than conventional crops.However,whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate.The common assumption then was that it could not be done.Throu
