Phenotypic variability and seed yield of Jatropha curcas L. introduced to Tunisia
Eight accessions of Jatropha curcas (six American and two African) were sown in the south of Tunisia (Gabès) to study its agricultural properties and development under local semi-arid conditions. Traits observed included general aspects of plant development (plant height, canopy circumference, numbe...

| description | Eight accessions of Jatropha curcas (six American and two African) were sown in the south of Tunisia (Gabès) to study its agricultural properties and development under local semi-arid conditions. Traits observed included general aspects of plant development (plant height, canopy circumference, number of nodes and seed yield); leaf characteristics (petiole length, limb length, limb width and foliar surface); and seed traits (size and shape). Morphological analysis of seeds included seed image area, perimeter, length/width ratio, circularity index and J index. This index reflects the similarity of seed images with an ellipse showing differences in seed shape between accessions. Jatropha curcas genotypes introduced in Tunisia are polymorphic, their seed yield is low and variable between genotypes. Seed morphology analysis gave an indication in relation with the productivity in some of the accessions. The comparative agronomic studies are crucial before early selection. |

Se sembraron en el sur de Túnez (Gabès) semillas de ocho accesiones de Jatropha curcas (seis americanas y dos africanas) para estudiar sus propiedades agrícolas y desarrollo en condiciones locales semiáridas. Los caracteres observados incluyen aspectos generales del desarrollo de planta (altura, circunferencia del follaje, número de nodos y producción de semillas); características de las hojas (longitud del peciolo, longitud del limbo, anchura del limbo y superficie foliar); y caracteres de la semilla (tamaño y forma). El análisis morfológico de las semillas incluyó el área de las imágenes, el perímetro, la relación longitud/anchura, el índice de circularidad y el índice J. Este índice refleja la semejanza de las imágenes de cada semilla con una elipse mostrando diferencias en la forma de las mismas entre accesiones. Los genotipos de J. curcas introducidos en Túnez son polimórficos, su producción de semilla es baja y variable entre genotipos. El análisis morfológico de las semillas da una idea en relación con la producción en algunas de las accesiones. Estudios agronómicos comparativos son cruciales antes de la selección.
