“…This general lack of guidance makes it difficult for those wanting to execute genomic selection practices in their own research [ 98 ]. Conversely, since its popularity as a user-friendly genome editing solution is increasing, CRISPR-Cas9 is becoming more widely available for use in both academia and the private sector [ 52 , 99 ]. Similarly, RNAi technology has been proven to be highly applicable to crop speed breeding efforts and has been put into practice across the field of agriculture [ 100 ].…”

As climate changes and a growing global population continue to escalate the need for greater production capabilities of food crops, technological advances in agricultural and crop research will remain a necessity. While great advances in crop improvement over the past century have contributed to massive increases in yield, classic breeding schemes lack the rate of genetic gain needed to meet future demands. In the past decade, new breeding techniques and tools have been developed to aid in crop improvement. One such advancement is the use of speed breeding. Speed breeding is known as the application of methods that significantly reduce the time between crop generations, thereby streamlining breeding and research efforts. These rapid-generation advancement tactics help to accelerate the pace of crop improvement efforts to sustain food security and meet the food, feed, and fiber demands of the world’s growing population. Speed breeding may be achieved through a variety of techniques, including environmental optimization, genomic selection, CRISPR-Cas9 technology, and epigenomic tools. This review aims to discuss these prominent advances in crop breeding technologies and techniques that have the potential to greatly improve plant breeders’ ability to rapidly produce vital cultivars.

“…Genome editing (GE) approaches have been transforming the fields of plant breeding and genomics by enabling precise genetic manipulation of crop species. The utilization of CRISPR/Cas9 holds significant promise in revolutionizing agriculture and creating opportunities for innovative developments in plant gene editing systems ( Chinnusamy et al., 2023 ; Saini et al., 2023 ). While the effectiveness of GE techniques has been demonstrated in other field crops and even in tree crops, it remains a relatively uncharted path for genetic improvement in palm species such as coconut, arecanut, or date palm, with the exception of oil palm.…”

Palms encompass over 2,500 species, across 200 genera, ranking second only to grasses (Poaceae) and legumes (Fabaceae) in the realm of agricultural food production and industrial applications. The coconut (Cocos nucifera L.), arecanut (Areca catechu L.), oil palm (Elaeis guineensis Jacq.), and date palm (Phoenix dactylifera L.) are among the economically significant perennial species within the Arecaceae family. Coconut, often referred to as the "tree of life," is celebrated for its diverse range of applications in food, nutrition, medicine, and various industrial uses (Ramesh et al., 2021). Coconut products encompass edible oil derived from the kernel or testa, tender coconut water, kernel, copra, coconut shell, coconut cake, wood-based products, coir pith, and items resulting from various valorization processes. The unopened spathe is tapped to extract inflorescence sap (neera), which can be further processed into jaggery, sugar, vinegar, and a variety of secondary products (Hebbar et al., 2022).Arecanut (Areca catechu L.) is a crop in tropical Asia and certain parts of East Africa. In India, it holds a prominent place as a major commercial crop and is also medically important, primarily grown in a few states of the country. Nevertheless, its commercial products are distributed throughout India, and the country undeniably leads in terms of both area under cultivation and production, accounting for 54% of the world's output. The fruit or nuts of the Areca catechu L. palm, commonly known as betel nut or supari, have a long history of use as a masticatory product by the Indian population, dating back to the Vedic period. As a result, arecanut is deeply intertwined with India's history and social heritage. On a global scale, the betel quid is used by as many as 600 million people in Asia alone.Date palm, on the other hand, thrives in arid regions such as Egypt, Iran, Saudi Arabia, and the UAE, among others (Aljohi et al., 2016). In addition to its fruit, date palm seeds also serve as a novel source of edible oil, further expanding its industrial applications (Ali et al., 2015). Oil palm stands out as an economically vital palm species, supplying approximately 35% of the world's vegetable oil. The genetic improvement of oil palm could play a pivotal role in global nutritional security.

“…2 Additionally, gene mutations introduced through gene editing are similar to natural mutations, making them more acceptable compared to genetically modified organisms (GMOs). In recent years, gene editing technology has been widely applied in various fields such as crop improvement 3 and disease treatment. 4 However, there is no unified consensus on a supervision, management, and evaluation system for gene-edited products in the international community.…”
