Comparison of modern breeding strategies and time required to develop novel plant varieties. (A) Conventional breeding: it is largely divided into cross and mutagenesis. Cross elite recipient line and donor line (with the desired trait, e.g., disease resistance, high-yielding) to improve trait. Mutagenesis randomly transforms using chemical or physical mutations and selects plants with the desired traits. (B) Genetic modification breeding: by introducing exogenous genes into elite varieties, they improve traits. (C) Genome editing: precisely modify the target sequence in the plant genome to improve traits. Figure based on Chen et al. (2019).
