Study Notes
- The Green Revolution of the 1960s helped feed the world's expanding population.
- Elite variety breeding, hybrid crop development, fertilizer use, and management advancements were used to achieve this with significant public investment.
- Many parts of the world benefited from the increase in food security that followed, which also enhanced agricultural growth.
- Reducing crop losses brought on by environmental variables, such as climate change, is necessary for future food security.
- Breeding and trait development have been accelerated by more current genomic technologies for greater environmental resistance and productivity.
- Genome-wide association studies and other gene mapping techniques combined with cutting-edge phenotyping tools make it possible to examine genetic variation with nucleotide-scale accuracy.
- Rapid selection of novel genetic combinations in top varieties is made possible by the discovery of loci that contribute to characteristics in conjunction with molecular marker-assisted breeding.
- The targeted editing of genomes using CRISPR-Cas technology is progressively accelerating advancements in the spatial and temporal management of altered genes and pathways.
- To make the necessary advancements in crop improvement, which can be fueled by genetic diversity and implemented by genome-scale breeding, precisely tuned gene engineering, and more precise agronomic management practices, a better understanding of plant mechanisms that increase yields in variable environments is crucial.
