Breeding Techniques

Traditional plant breeding depends on spontaneous and induced mutations available in the crop plants. Such mutations are rare and occur randomly. By contrast, molecular breeding and genome editing are advanced breeding techniques that can enhance the selection process and produce precisely targeted modifications in any crop. Identification of molecular markers, based on SSRs and SNPs, and the availability of high-throughput (HTP) genotyping platforms have accelerated the process of generating dense genetic linkage maps and thereby enhanced application of marker-assisted breeding for crop improvement. Advanced molecular biology techniques that facilitate precise, efficient, and targeted modifications at genomic loci are termed as “genome editing.” The genome editing tools include “zinc-finger nucleases (ZNFs),” “transcription activator-like effector nucleases (TALENs),” oligonucleotide-directed mutagenesis (ODM), and “clustered regularly interspersed short palindromic repeats (CRISPER/Cas) system,” which can be used for targeted gene editing. Concepts of molecular plant breeding and genome editing systems are presented in this chapter.

Climate change and population size records threaten food security. Therefore, the call for a more sustainable and efficient crop production has never been more urgent. Traditional plant breeding was one of the first successful approaches to expand cultivation areas and crop yield. Later, biotechnological tools and their products, such as genetically modified organisms containing exogenous DNA, further broadened the limits of agricultural results, yet bringing huge financial, bureaucratic, and public rejection hurdles. In the 90s, scientific advances brought the opportunity to drive mutations using engineered nucleases, and since 2013 CRISPR-Cas has emerged as the most practical toolkit to edit genomes. One of the most striking possibilities is to generate edited and non-transgenic plants. In this review, we present the working mechanism behind CRISPR-induced mutations and pinpoint the latest techniques developed, as well as its myriad of applications in agriculture. The enhancing scope of CRISPR ranges from introducing traits of agronomic interest – such as herbicide resistance, resistance/tolerance to biotic and abiotic stresses, and quality and durability of products – to accelerating plant breeding processes, including haploid induction, generating male-sterile lines, fixating hybrid vigor, and overcoming self-incompatibility. We also discuss regulatory issues surrounding edited plants and derived products around the world, challenges that must be overcome, and future prospects to harness all the potential of this amazing tool to guarantee the new crop production revolution.
