Plant breeding is the continuous effort to develop superior plant phenotypes better adapted to human needs by utilizing available genetic variation. It has been practiced for thousands of years, starting as an art by farmers and later as a science by breeders. The goal is to improve the quality, diversity, and performance of economically important crops. Crop breeding is a rapidly advancing science that uses recent genetic and biotechnological innovations to develop better crop varieties. After Mendel's initial genetic work on garden peas, interest in plant breeding increased in the late nineteenth century. Conventional breeding techniques led to the Green Revolution between 1960 and 1980, significantly increasing wheat and rice production. Advances in plant biotechnology, molecular markers, and genomics have enabled breeders to develop new tools for analyzing and manipulating genetic variability. Molecular tools are increasingly used in plant breeding to meet global needs for sustainable agricultural productivity. Hunger and malnutrition are pressing global health issues. The UN projected a 25% increase in world population by 2020, reaching 7.5 billion. According to FAO estimates, the number of undernourished people increased to 815 million in 2017. Food insecurity and malnutrition have serious public health consequences and reduce human potential. The situation is worsening due to decreasing land available for crop production. The solution lies in integrating the latest innovations in plant biology and genetics to enhance crop improvement through plant breeding. The aim of plant breeding is to improve the quality, diversity, and performance of agricultural and horticultural crops. These changes are permanent and heritable. Mendel's work in the mid-nineteenth century provided the foundation for conventional plant breeding. Breeding has been the basis of agriculture by creating genetically diverse populations and selecting for desirable traits. Modern selection is driven by biological assessments and genetic insights. Progress is measured by genetic gain, influenced by genetic variation, selection intensity, and time.Plant breeding is the continuous effort to develop superior plant phenotypes better adapted to human needs by utilizing available genetic variation.
