Abstract :
The cross-pollinated nature of the cashew tree and the use of non-selected nuts lead to the coexistence of multiple cashew varieties with unknown and highly variable characteristics within the same plantation. This genetic diversity, combined with pedoclimatic variability, often results in the unsuitability of certain genotypes to specific environments, thereby limiting their productive potential. Furthermore, the absence of a structured classification system and the lack of standardized selection criteria pose significant systematic challenges in identifying and promoting elite varieties. To improve yields, some producers opt for grafted plants, which, although costly, do not always guarantee uniformity due to insufficient characterization of the genetic material. This practical limitation perpetuates heterogeneity within plantations and reduces the adaptability of certain grafted plants to specific pedoclimatic zones. In addition, poor agronomic practices and inadequate technical support hinder the optimal exploitation of genetic resources. On a technical level, the lack of knowledge regarding the genes responsible for key morphological and phenotypic traits represents a major obstacle to breeding and varietal selection programs. The absence of molecular markers and efficient propagation techniques further complicates the establishment of high-yielding and climate-resilient plantations. This study aims to synthesize existing knowledge on the cashew tree worldwide, establish a comprehensive database of relevant research, and identify promising strategies to enhance the valorization of the species.
