Abstract EN
This study aimed to characterize eight accessions of Vicia narbonensis L.
originated from different Mediterranean countries.
The cytology of these species is rarely known despite the fact of its great socio-economical and ecological interest in these arid and semi-arid zones.
This work aimed mainly to characterize the karyotype, morphological pod and seed traits of the species.
Karyotypes of all accessions were similar to a diploid number of 2n =2x = 14.
All the accessions have submetacentric chromosomes with a secondary constriction attached to the long arm of pair VII close to the centromere.
Variation in chromosome size was observed; it ranged from 5.86 lm to 7.62 lm.
Indices of karyotype asymmetry were calculated as the total form percentage (TF%) and symmetric indices (Syi) which ranged from 33.75% to 35.42% and from 51.01% to 54.85%, respectively.
The predominance of submetacentric chromosomes indicated that the karyotype is symmetrical and can be considered as primitive.
However, the analysis of quantitative parameters measured on pods and seeds showed a significant variation between accessions.
A relationship between centromeric index and the pod beak length was found.
Estimation of phenotypic diversity using the Shannon diversity index (H0) showed that the length, the seed color and the number of seeds per pod are the most polymorphic traits with respectively, H0 = 0.92, 0.80 and 0.83.
Cluster analysis of karyological, pod and seed traits showed four groups of accessions.
This clustering is partially due to the geographical origin of the studied accessions.
The variation in chromosome size, pod and seed traits could offer potentially valuable genetic resources for the improvement of V.
narbonensis which is considered as neglected and underutilized crop species (NUCS).
