Evaluación del comportamiento de especies silvestres de almendro en un escenario de estrés hídrico. Listados de especies silvestres de almendro tolerantes y sensibles a estrés hídrico

Abstract

Se evaluó el comportamiento de especies silvestres de almendro frente al estrés hídrico, buscando identificar variedades tolerantes y sensibles. En 2023 y 2024 se propagaron in vitro especies como Prunus webbii, P. kostchii, P. mira y otras seis más, logrando su establecimiento exitoso. Además, se realizó un estudio de asociación del genoma completo (GWAS) en 140 genotipos (silvestres, comerciales, locales y modernos) del banco de germoplasma de Prunus (CITA), relacionando variabilidad genética con el uso eficiente del agua (UEA) a través del análisis del isótopo Δ13C. Valores bajos de Δ13C indicaron mayor eficiencia en el UEA. Las especies silvestres analizadas, junto a variedades como Mardía®, Vialfas® y ‘Guara’, mostraron mejores UEA. El GWAS permitió identificar 45.350 SNPs y reveló tres grupos poblacionales según origen y estatus, con solapamiento entre accesiones silvestres y variedades locales. Finalmente, se detectaron dos regiones genómicas clave (en cromosomas PD06 y PD08) asociadas al UEA, útiles para el desarrollo de futuros marcadores moleculares en el programa de mejora genética del almendro.

El proyecto Biodiversa forma parte del Plan Complementario de I+D+i de Agroalimentación AGROALNEXT dentro del Plan de Recuperación, Transformación y Resiliencia financiado por la Unión Europea – Next Generation EU.
