    Agricultural production system is extremely vulnerable to climate change, and this change will heavily affect the grain yields, thereby threating the food security worldwide. People from developing countries are at greatest risk of experiencing food insecurity, and today, millions of people are going to bed hungry. Wheat is serving as a staple food for millions of people around the world. Development of high-yielding wheat varieties during the Green Revolution is considered an important event in agricultural history. However, these plant breeding activities also resulted in genetic erosion in wheat. Moreover, it is also believed that after domestication process, selection process also resulted in the loss of genetic diversity of wheat. Therefore, commercial wheat cultivars are prone to various biotic and abiotic stresses. To combat with climate changes and to serve enough quantity of food with quality, there is a need to harness wheat landraces. Landraces are considered as repository of gene pool that enhance the biodiversity and maintain and stabilize the ecosystem in a sustainable way to make it functional. Wheat landraces are traditional crop populations developed by the farmers through natural and human selection under their years of cultivations and have adaptation to local environment and management practices. Wheat landraces have more genetic diversity compared to their cultivated ones, and breeding community has utilized their potential in development of climate-resilient wheat cultivars. Here, we are exploring the role of landraces in wheat breeding and hoping that provided information will catch the attention of breeding community to collect, conserve, and perform breeding activities using wheat landraces. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

    Origin, Taxonomy, and Distribution of Ancient Wheats in Turkey
    (Springer International Publishing, 2022) Baloch, Faheem Shehzad; Aktaş, Hüsnü; Rasheed, Awais; Nadeem, Muhammad Azhar; Cabi, Evren; Hatipoğlu, Rüştü; Sajjad, Muhammad
    Ancient wheats “einkorn (Triticum monococcum ssp. monococcum), emmer (T. turgidum ssp. dicoccum) and spelt (T. aestivum L. ssp. spelta),” which are diploid, tetraploid, and hexaploid wheats, respectively, are also known as “ancient wheat (also termed as farro).” Ancient wheats are not only a promising source of many important traits related with biotic and abiotic stresses for modern wheat improvement, but they are also attracting renewed interest for cultivation due to the global efforts in enhancing food diversity. The exploitation of ancient species is seen as a key factor to further drive genetic improvements in wheat breeding programs worldwide. Therefore, it is of utmost importance to have information about the taxonomy of the ancient wheats to design a breeding for tetraploid and hexaploid wheat for the growing population of the world. For designing the breeding program, we need to introgress favorable alleles from these precious ancient wheat genetic resources. Turkey, one of the most important diversity and domestication centers of wheat, harbors frequent distribution of the various diploid and tetraploid ancient wheat species. In this chapter, we tried to summarize the phylogenetic and taxonomic relationship of various ancient wheat species belonging to different ploidy levels and their distribution areas in Turkey. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
