Final answer:
Hybridization of important cereal crops like rice, maize, and wheat to enhance productivity and disease resistance.
Explanation:
Hybrid Rice: Rice is a crucial food crop grown worldwide. There are two major cultivated rice species, Oryza glaberrima and Oryza sativa L. Hybrid rice research aims to develop varieties that exhibit heterosis for increased yields.
Hybrid Maize and Wheat: Maize, wheat, and other cereal crops have benefited from hybridization to enhance yield and resistance to diseases. Breeding approaches like combining desired genes from different varieties have boosted agricultural productivity.
Crop Hybridization: Crops like wheat, rice, and maize have seen advancements in hybrid cultivars to improve yields. Maintaining genetic diversity among wild crop relatives is vital for developing resistance to pests and diseases.
