“…Another explanation is the co‐presence on the same territory of Arabic‐speaking minorities (sedentary Bedouins, especially Awlad ‘Alī, Battesti et al, ) who use these Arabic names; for example, rather than the names tasutet/ alkak/ úšik, they will systematically use (or even only know) the names ṣaɛidi/ freḥī/ azzawī to denote the same palms. Besides, we observed that local practices of categorization and integration of seedlings can lead, as explained above, to a massive phenomenon of underestimation of agrobiodiversity for an uninitiated external observer and all assessments have stumbled over this obstacle (even the recent Atlas of date palm in Egypt , El‐Sharabasy & Rizk, ).…”

“…Extrapolating from early 20th century data in Siwa, an estimate of 82% of the dates in value terms was exported (and 95% of the elite cultivar ṣaɛidi) (Hohler & Maspero, ). Several population genetics analyses focused on date palm agrobiodiversity in Siwa (Abd El‐Azeem, Hashem, & Hemeida, ; Abou Gabal, Abedel Aziz, Hardash, & El‐Wakil, ; El‐Sharabasy & Rizk, ; el‐Wakil & Harhash, ; Hemeid, Sanaa, & Abd El‐Rahman, ; Selim, El‐Mahdi, & El‐Hakeem, ). Nevertheless, none of these studies integrate agricultural knowledge and practices, and the existing diversity in Siwa Oasis and its categorization system remain thus poorly understood.…”

Crop diversity is shaped by biological and social processes interacting at different spatiotemporal scales. Here, we combined population genetics and ethnobotany to investigate date palm (Phoenix dactylifera L.) diversity in Siwa Oasis, Egypt. Based on interviews with farmers and observation of practices in the field, we collected 149 date palms from Siwa Oasis and 27 uncultivated date palms from abandoned oases in the surrounding desert. Using genotyping data from 18 nuclear and plastid microsatellite loci, we confirmed that some named types each constitute a clonal line, that is, a true‐to‐type cultivar. We also found that others are collections of clonal lines, that is, ethnovarieties, or even unrelated samples, that is, local categories. This alters current assessments of agrobiodiversity, which are visibly underestimated, and uncovers the impact of low‐intensity, but highly effective, farming practices on biodiversity. These hardly observable practices, hypothesized by ethnographic survey and confirmed by genetic analysis, are enabled by the way Isiwans conceive and classify living beings in their oasis, which do not quite match the way biologists do: a classic disparity of etic versus. emic categorizations. In addition, we established that Siwa date palms represent a unique and highly diverse genetic cluster, rather than a subset of North African and Middle Eastern palm diversity. As previously shown, North African date palms display evidence of introgression by the wild relative Phoenix theophrasti, and we found that the uncultivated date palms from the abandoned oases share even more alleles with this species than cultivated palms in this region. The study of Siwa date palms could hence be a key to the understanding of date palm diversification in North Africa. Integration of ethnography and population genetics promoted the understanding of the interplay between diversity management in the oasis (short‐time scale), and the origins and dynamic of diversity through domestication and diversification (long‐time scale).

“…Phenotypicrevealed markers assess genetic diversity and performance of germplasm versus the attribute (Mahdy, 2012). These markers are based on visual observations (El-Sharabasy et al, 2021; and screen the quantitative traits to increase field crop production. PCR (polymerase chain reaction) -based markers are applied for genetic improvement and breeding, genetic diversity, and genetic relationships (Chen et al, 2008;.…”

Genetic improvement of faba bean (Vicia faba L.) genotypes selected for resistance to chocolate spot disease

et al. 2022

Inter-varietal hybridization is a powerful tool for genetic improvement and production of new genotypes for a trait of interest. Four parents of faba beans (Vicia faba L.) were hybridized using agromorphological and molecular characterization to obtain genotypes resistant to the chocolate spot disease. The study was done at the Nubaria Research Station, Giza, Egypt. Eight traits including resistance to chocolate spot, days to flowering, plant height (cm), number of branches/plant, number of pods/plant, number of seeds/plant, 100-seed weight (g), and seed yield/plant were estimated during the three growth seasons of 2016/2017, 2017/2018, and 2018/2019. Genetic parameters revealed by RAPD and ISSR markers assessed the genetic variation of genotypes with their generations. Crosses 1 (P1 “Nubaria-1” x P2 “Sakha-1”), 2 (P1 “Nubaria-1” x P3 “T.W”), and 3 (P1 “Nubaria-1” x P4 “Camolina”) revealed high resistance to disease with high yield. Markers patterned specific loci of resistant parents at a length of 360, 470, 450, 660, and 140 bp in RAPD and 1100, 810, 650, 700, 480 bp in ISSR. Inter-varietal hybridization between the resistant and susceptible genotypes is considered one of the most promising methods to obtain germplasm with resistance and high yield.
