Sentences with phrase «crop varieties»
"Crop varieties" refers to different types or kinds of plants that have been selectively bred or genetically modified to have specific traits, such as improved yields, resistance to diseases or pests, or better tolerance to certain climates or growing conditions. These varieties allow farmers to choose the plants that best suit their needs and increase the diversity of crops that can be grown. Full definition
