Wheat Landraces

Landraces are dynamic populations of cultivated plants with a large genetic base, diverse genetic makeup, and local adaptation. They are of great interest to plant breeders due to their resistance to biotic and abiotic stress factors and gene pools for wheat breeding. 75% of crop plant genetic diversity was lost in the last century, making it urgent to preserve existing species for food security.

Landraces are remarkable populations of cultivated plants with a rich genetic base, exhibiting dynamic characteristics and a historical origin. They possess a distinct identity and are free from any formal crop improvement efforts. These landraces often showcase remarkable genetic diversity, being locally adapted to specific environments and closely associated with traditional farming systems. The presence of diverse resistance genes to biotic and abiotic stress factors, particularly abundant in landraces, holds immense interest for plant breeders, as they grapple with the challenges posed by global climate change. Furthermore, the combination of gene pools derived from different landraces cultivated under diverse ecological conditions can be invaluable in wheat breeding programs, aimed at enhancing quality, yield, and other desirable agricultural parameters. It is disheartening to note that approximately 75% of the genetic diversity of crop plants has been lost in the last century, primarily due to the widespread adoption of high-yielding modern varieties. This loss underscores the urgent need to preserve existing species, not only for future generations but also to ensure a secure food supply for a rapidly growing global population.

In this book, we offer a comprehensive overview of wheat landraces, focusing on their genetic diversities, conservation, and utilization. We explore the rich tapestry of genetic variations found within landraces, highlighting their potential for sustainable agriculture and food security. We also delve into the strategies employed to conserve and maintain these valuable genetic resources, ensuring their long-term viability. Moreover, we discuss the various applications of landraces in modern breeding programs, leveraging their unique traits to develop new crop varieties with improved characteristics. By understanding the significance of wheat landraces, we can work towards a more resilient and sustainable food system, preserving the diversity of plant species and ensuring a healthy future for generations to come.
