Zoology - Strategies for Enhancement in Food Production Question with Solution | TestHub

A wide range of fungal, bacterial and viral pathogens, affect the yield of cultivated crop species, especially in tropical climates. Crop losses can often be significant, up to 20-30 percent, or sometimes even total. In this situation, breeding and development of cultivars resistant to disease enhances food production. Some of the diseases caused by fungi are rusts, e.g., brown rust of wheat, red rot of sugarcane and late blight of potato; by bacteria– black rot of crucifers; and by viruses – tobacco mosaic, turnip mosaic, etc.
