| 英文摘要 | Egyptian clover (Trifolium alexandrinum) has received limited attention regarding its genetic diversity, rendering it susceptible to climate change. To develop resilient Berseem cultivars, exploring its genetic resources is vital for enhancing the diversity within its germplasm, thereby optimizing breeding programs. The examination of 24 Berseem accessions. Using three different molecular marker types; Inter-Simple Sequence Repeat (ISSR) (10 primers), Start Codon Targeted polymorphism (SCoT) (22 primers), and Sequence-Related Amplified Polymorphism (SRAP) (17 primer combinations) revealed a high genetic variability. ISSR markers had the highest polymorphism rate (82.2%) compared to SCoT (69.6%) and SRAP (65.2%). Unweighted Pair Group Method with Arithmetic Mean clustering analysis divided the studied accessions into two major groups, supported by STRUCTURE analysis, which also split samples into two subpopulations ( Delta K = 2). Additionally, this classification was verified by both principal component analysis and a heat map. The study underscores the importance of Berseem's genetic diversity in crop development and breeding, with ISSR markers offering valuable insights due to their high polymorphism. Despite the diverse geographic origins of the accessions, the lack of geographic clustering implies significant genetic mixing, possibly because of high outcrossing facilitated by insect pollination or self-incompatibility. The combined use of multiple markers deepens our understanding of Berseem's genetics by providing more detailed and comprehensive coverage of the clover genome, allowing for increased resolution, validation of results, and a holistic perspective on the genomic landscape, furthermore, identifying and recommending specific Berseem accessions (NGB-43724, NGB-19680, Gemeiza1, and Giza6) as prospective candidates for future breeding programs in Egypt. |
