Interpretive Summary:

Technical Abstract: Phenotypic diversity was estimated for 20 vegetative and reproductive traits in a safflower germplasm collection of 630 accessions from 12 Middle Eastern countries. Accessions were clustered in 9 distinct groups based on all vegetative and reproductive traits, as well as their tolerance to salinity. Thermal time to flowering, rosette period and physiological maturity were among the most diverse traits in the collection. Oil-, forage-, and ornamental-types were identified and constituted 65, 27 and 8% of the collection, respectively. These three groups have distinct phenological and morphological characteristics; however, about 20% of the forage-type had approximately similar oil content as the oil-type accessions. The forage-type accessions, with profuse branching and long vegetative growth stage, were the most tolerant to salinity. Accessions were selected, based on the overall phenotypic diversity and tolerance to salinity, for further development as source for oil, forage and food coloring germplasm.
