CRISPR/Cas is a genome editing technique, permits accurate improvement of fiscally significant yield species by transgenic and non-transgenic strategies. We have reviewed CRISPR/Cas9 with or without DNA solution design in both maize as samples to redesign tolerance against dry season obstruction, improving seed’s oil contents production, and a gift of herbicide strength. Fundamentally, by exploiting the technologies of CRISPR/Cas9, development with late advances in plant tissue culture can be brought directly into monetarily significant genotypes. The various crop species are major agricultural products and play an indispensable role in sustaining human life. Over a long period, breeders strove to increase crop yield and improve quality through traditional breeding strategies. Today, many breeders have achieved remarkable results using modern molecular technologies. Recently, a new gene-editing system named the clustered regularly interspaced short palindromic repeats CRISPR/Cas9 technology has also improved crop quality. It has become the most popular tool for crop improvement due to its versatility. It has accelerated crop breeding progress by its precision in specific gene editing. This review summarizes the current application of CRISPR/Cas9 technology in crop quality improvement. It includes the modulation in appearance, palatability, nutritional components, and other preferred traits of various crops. Assortment created through such CRISPR/Cas9 engaged advanced raising procedures can be muddled from the regularly happening assortment and appropriately should be quickly open for commercialization.
