Until recently, there has been no set of model descriptors for date palm (Phoenix dactylifera L.). We propose here a system of descriptors for date palm to meet the needs of genebanks, in situ and ex situ conservation activities, and as an aid in diversity studies. Multi-score and bi-state systems are used to express the date palm traits. We have compiled standard passport data (17 parameters); details of eco-geography (13 parameters); ethno-botany (15 parameters); management (18 parameters); characterization (58 vegetation parameters, 27 fruit parameters, 22 seed parameters, 41 inflorescence parameters, 4 molecular marker parameters, 5 cytological parameters and 24 biochemical parameters); and evaluation activities (66 biotic stress parameters and 13 abiotic stress parameters). These attributes were derived from 1275 samples representing 55 varieties cultivated in Egypt. Trait data were collected both from trees growing in their natural habitats as well as from trees growing ex situ on the farm of the Central Laboratory of Date Palm Research and Development (CLDPRD) genebank. The proposed date palm descriptors provide a standardized information set for all characterization and evaluation activities for date palm genebanks.
