“…Thomson et al [47] identified the "saltol" QTL that is involve into controls the Na + / K + ratio at the seedling stage in shoot using a conventional breeding approach in rice. According to Hasan et al [48] one method of effective conventional breeding is marker-assisted backcrossing used to transfer alleles at target loci. Hence, the implementation of conventional breeding approaches shows limitations to handle the QTL character like salt tolerance in wheat crop improvement programs.…”

Cereal crops including rice, wheat, corn, sorghum, pearl millet and small millet, are grown for food, feed and fuel in crop-livestock based agricultural systems around the world. Soil salinity occupies an important place among the soil problems that threaten the sustainability of agriculture in a wide area around the world. Salinity intensity is predicted to exacerbate further due to global warming and climate change, requiring greater attention to crop breeding to increase resilience to salinity-induced oxidative stress. Knowledge of physiological responses to varying degrees of oxidative stress has helped predict crop agronomic traits under saline ecosystems and their use in crop breeding programs. Recent developments in high-throughput phenotyping technologies have made it possible and accelerated the screening of vast crop genetic resources for traits that promote salinity tolerance. Many stress-tolerant plant genetic resources have been developed using conventional crop breeding, further simplified by modern molecular approaches. Considerable efforts have been made to develop genomic resources which used to examine genetic diversity, linkage mapping (QTLs), marker-trait association (MTA), and genomic selection (GS) in crop species. Currently, high-throughput genotyping (HTPG) platforms are available at an economical cost, offering tremendous opportunities to introduce marker-assisted selection (MAS) in traditional crop breeding programs targeting salinity. Next generation sequencing (NGS) technology, microenvironment modeling and a whole-genome sequence database have contributed to a better understanding of germplasm resources, plant genomes, gene networks and metabolic pathways, and developing genome-wide SNP markers. The use of developed genetic and genomic resources in plant breeding has paved a way to develop high yielding, nutrient-rich and abiotic stress tolerant crops. Present chapter provides an overview of how the strategic usage of genetic resources, genomic tools, stress biology, and breeding approaches can further enhance the breeding potential and producing salinity-tolerant crop varieties/lines.

“…However, it was reported that this may induce somaclonal variation within regenerants [ 9 ]. Using plentiful and reliable sources, such as the immature female inflorescences of date palms, is considered the most promising method for the propagation of elite varieties of female and male date palms [ 10 ]. The use of the immature female inflorescences method will shorten the time required for the production of a large number of date palm plants to 1 to 2 years, compared to 3–4 years in the case of using a shoot tip.…”

Immature female inflorescences are promising materials for use as explants for the tissue culture of date palm. Four types of MS media were used in this study during the four micropropagation stages—starting media (SM), maturation media (MM), multiplication media (PM) and rooting media (RM)—to micropropagate three elite date palm varieties, Amri, Magdoul and Barhy using the immature female inflorescences as explant. The highest percentage of callus induction in all the varieties studied was obtained on the SM1 (9 µM 2,4-D + 5.7 µM IAA + 10 µM NAA). Culturing on the MM1 (4.5 µM 2,4-D + 9.8 µM 2-iP + 1.5 AC) allowed us to obtain the best value in terms of callus weight. After culturing on the PM1 (4.4 µM BA + 9.8 µM 2-iP) produced the highest numbers of somatic embryos and shoots. The explants on RM2 (0.5 µM NAA + 1.25 µM IBA + 3 g AC) showed the highest root numbers and root lengths, while the highest shoot length was achieved on RM3 (0.5 µM NAA + 0.5 µM IBA + 3 g AC). The Amri variety presented the best response among the three varieties in all parameters, followed by the Magdoul and Barhy varieties. In all the stages of micropropagation, the analysis of variance revealed highly significant variations among varieties and culture media, and a significant difference in the number of roots during the rooting stage. The results also showed non-significant differences in the interaction between varieties and culture media, except for shoot length in the rooting stage. The results also reveal the broad sense heritability ranging from low to high for the measured parameters. It can be concluded that the immature female inflorescences can be used as a productive explant source for successful date palm micropropagation using the SM1, MM1, PM1 and RM2 culture media. It can also be concluded that the success of date palm micropropagation not only depends on the concentrations of growth regulators, but also on their types.

In many parts of Asia, especially in the regions which are arid in nature, present in the Middle East, the date palm, i.e. Phoneix dactylifera L., is a significant plant both culturally and economically. In the last decade, many biotechnological tools have been applied to revolutionize date palm research and its cultivation process. In this comprehensive review, we provided an in-depth overview of the cutting-edge developments in date palm biotechnology, mentioning the critical areas such as genomics, genetic engineering, in vitro propagation and incorporation of artificial intelligence and machine learning (AI-ML). These advancements in date palm production led to the production of superior date palm cultivars with improved harvest, fruit traits, and resilience to biotic and abiotic stresses. Also, it explores the application of biotech tools in enhancing pest and disease management strategies, increasing productivity, and developing Date palm-based bio-factories for the synthesis of high-value compounds. This review highlights the current challenges faced by the date palm industries, including limited water resources, genetic erosion, pests and disease and the need for improved postharvest handling and processing. It examines how these tools, coupled with AI-based approaches, can be leveraged to address these challenges and ensure the long-term sustainability of date palm cultivation.
