Capsule shattering in sesame is a major agronomic constraint that reduces yield stability and limits mechanized harvesting efficiency. To address this challenge, 200 genetically diverse sesame genotypes from Sudan were genotyped using genotyping-by-sequencing (GBS) and evaluated for three consecutive seasons under field conditions for shattering type (ST), type of capsule beak (TCB), and bicarpellate capsule shape (BS). The re...

Sudan is the birthplace of sorghum, and vast genetic diversity exists among its wild relatives. To assess the genetic potential of Sudan wild sorghum accessions, we used 41 stay-green-specific microsatellite (SSR) markers to analyze the genetic variability and population structure of 256 accessions. Overall, 17 SSR markers were polymorphic, with 55 alleles on average 3.3 per locus. The polymorphic information content (PIC) ran...

Striga hermonthica , a parasitic weed, poses a significant threat to sorghum production in sub-Saharan Africa, potentially causing yield losses of up to 100%. Identifying sources of Striga resistance trait within the diverse wild sorghum accessions is imperative to developing resistant sorghum cultivars. This study analyzed the genetic variation of 255 Sudanese wild sorghum accessions using simple sequence repeat (SSR) markers...

Stem rust [causal organism: Puccinia graminis f. sp. tritici ( Pgt )], stripe rust [ Puccinia striiformis f. sp. tritici ( Pst )], and leaf rust [ Puccinia triticina ( Pt )] are important fungal diseases of wheat in Central Asia and worldwide. Therefore, identification of seedling and adult plant resistance (APR) genes is of major importance for the national wheat breeding program in many countries. The objectives of this stud...
