Despite their vital contribution to agriculture, rural women frequently face significant barriers to accessing essential resources, including land, credit, and agricultural services. Yet they are vital to sustaining agri-food systems, particularly in the Global South. On International Day of Rural Women, we honor rural women for their invaluable contributions to advancing agriculture in the face of accelerating climate change.

Genetic diversity of 45 genotypes were shown in the list of genotypes Azerbaijani durum wheat (Triticum durum Desf.) genotypes were screened using simple sequence repeats (SSRs). These accessions were collected from various bioclimatic regions of Azerbaijan. Out of the used 22 primers, 13 primers showed polymorphism and were selected for the analyses. Among the genotypes under study, 31 alleles were detected. The highest number of alleles was detected in locus gwm 335 (on chromosome 5B) and on locus gwm 445 (on chromosome 2A) with 5 and 4 alleles, respectively. The lowest number of alleles was found in locus gwm 617 with only 1 allele. For A, B, and D genomes, the total number of alleles detected was 14, 15, and 2, respectively. PIC value between studied SSR markers was 0.912 and this result shows high genetic diversity between Azerbaijani durum wheat genotypes. Therefore, these primers can be recommended for studying the genetic diversity of Azerbaijani durum wheat accessions. The genetic structure of the genotypes was analyzed and the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) dendrogram revealed five major clusters using Nei genetic distance index. The results revealed that SSR markers can efficiently evaluate genetic variation in the wheat samples. Based on the previous characterization of the drought response of these genotypes, links could be established between the SSR markers and drought tolerance. If some of the SSR markers are confirmed for their association with drought tolerance, then, they can be used as markers for the identification of drought-tolerant cultivars needed to enhance wheat productivity for farmers dealing with harsh conditions.

Water stress causes large agricultural losses worldwide and deteriorates its quality. Drought tolerance in plants is a complex trait governed by multigenes and infleunce of various environmental factors affecting the expression of these genes. Thus this complexity necessitates the application of new molecular methods to identify and develop drought tolerant genotypes. The present study was conducted to investigate the genetic diversity of 45 Azerbaijani wheat (Triticum aestivum L.) core collection genotypes utilizing simple sequence repeat (SSR) markers associated with drought tolerance. Our results showed that nine primers out of twelve showed polymorphism. Maximum number of alleles were detected for WMC177 marker (on chromosome 2A), WMC 264 (on chromosome 3A) and WMC219 (on chromosome 4A) with 5, 5 and 4 alleles, respectively. The lowest alleles were determined for WMC219 marker (chromosome 4A) with only one allele. The total number of the detected alleles on A and D genome was 18 and 11 respectively. The maximum number of unique bands (3) was scored with pimer WMC 177. Seven genotypes (cv Gobustan, and Gizil bugda, landrace 6262, and research materials 6170, 6286, 6296 and 6293) possessed unique bands. Based on polymorphism analysis of the wheat genotypes by SSR markers, drought tolerant genotypes for utilization in breeding programs were selected.

The root lesion nematode, Pratylenchus thornei, causes high yield losses in rainfed wheat fields in Morocco, as well as worldwide. Growing resistant varieties is one of the most effective methods for controlling nematodes. Therefore, a collection of 69 wheat lines (Triticum aestivum and T. durum), provided by the National Institute of Agricultural Research (INRA-Meknes, Morocco) and the International Center for Agricultural Research in the Dry Areas (ICARDA-Rabat, Morocco), were screened for resistance to P. thornei in tubes (15 × 20 × 120 mm3) under greenhouse conditions. The resistance level was evaluated based on the number of nematodes extracted from roots and soil 9 weeks after infestation. Three lines, L3 (DW-37), L14 (DW-37), and L54 (USG3535), were found to be moderately resistant (Reproduction factor <1) to P. thornei.
