DATA FILES DESCRIPTION:
Genotypic data (SSRs)
Alleles’ size without the M13 tail. Genotyping was done using a 24-capillary 3500xL System
(Applied Biosystems) and GeneMapper v 4.1 (Applied Biosystems) was used for genotype
scoring.
Missing data are coded “999”.
Morphological data
Morphological characteristics of the panicles collected on the plants which were genotyped.
Eight morphological descriptors were selected from the IPGRI descriptors and were
completed by seven additional descriptors for seeds and glumes characteristics that showed
variability on the sorghum collected in our study area.
Missing data are coded “NA”.

Variety name (as reported by farmers)
houehold_ethny
Ethnolinguistic group of the farm’s house head
Cycle_length
Growth cycle length of the variety (according to the farmer in
charge of seed selection in the farm visited. S: short cycle, R:
long cycle)
Origin
Improvement status of the variety (I : improved – formal
breeding system, L: Local – landrace)
Structure_K4_q_0.8
Assignment according to STRUCTURE software for K = 4.
individuals whose estimated proportion of genome
originating from one population (q, hereafter admixture
coefficient) was below a 0.8 threshold were considered as
resulting from admixture between the populations
(unassigned). Individuals whose q value was equal to or
above 0.8 for a population were assigned to that population
(hereafter cluster).
