Micropropagation of zygotic embryos from genetically diverse almond seedling orchards in eastern Morocco

Numerous studies on perennial crops have shown that almond has a low tolerance to climate change, which led detailed study for its adaptation by focusing selecting heat-tolerant varieties. The long period of agriculture creates particular challenges in changing climate. risk complicates the choice variety best current may be poorly suited future climates. Hence interest having large variability tolerant genotypes. In eastern Mediterranean region Morocco, seedling trees are largely grown, created an important gene pool, both breeding programs and selection superior genotypes adapted difficult pedo-climatic conditions. For conservation crop biodiversity these groves, micropropagation is considered feasible technique producing regenerating planting materials. Zygotic embryos several local ecotypes native population known as ''Beldi'' were cultivated Murashige Skoog (MS) medium supplemented with different concentrations combinations auxins cytokinins. results showed multiple shoot initiation from zygotic MS containing 1mg/L 6-Benzyl-aminopurine (BAP) combined 0.5 mg/L Indole butyric acid (IBA). A high rooting rate was obtained half-strength IBA.
