A study of Corchorus L. diversity in Egypt using high-throughput phenotyping platform (HTPP): an Egyptian gene bank example

Biodiversity and identification facilitate a prioritization of determination basis for plant evolutionary, phytogeography, biodiversity and conservation of plant genetic resources. High-throughput phenotyping platforms (HTPP) provide more attractive for genotyping for biodiversity evaluation. Descriptor lists include 51 attributes applied on all growth-stages of 53 C. olitorius accessions plus C. capsularis , C. trilocularis , C. tridens , and C. depressus . Three main groups were split. Variance decomposition was estimated within class of 68.87% and between classes of 31.13%. Major distance recorded 18.41 between class 1 (wild taxa only) and class three (18 accessions of C. olitorius ). In contrast, the minor distance scored 8.3 between class 2 (35 accessions) and class 3 (18 accessions). Wild taxa with their rarity distribution and habitats prioritize highly conservation due to the association of evolutionary role and importance of genetic improvement. Conservation strategies applied to PGR prioritization are influenced by the distribution frequency and habitat specificity. The results are useful information on genetic diversity at the Egyptian Gene Bank, which could be used for C. olitorius genetic improvement programs and sustainable utilization.
