Sesame (Sesamum indicum L.) plays a crucial role in Ethiopian agriculture, serving both subsistence and commercial purposes. However, our understanding of the extensive genetic diversity population structure sesame remains limited. To address this knowledge gap, we genotyped 368 germplasms, categorizing into four distinct breeding groups: Accessions, landraces, improved varieties, wild types, using comprehensive set 28 polymorphic markers, including 23 simple sequence repeat (SSR) 5 Insertion-Deletion (InDel) markers. These markers ensured robust genomic representation, with at least two per linkage group. Our results unveiled substantial diversity, identifying total 535 alleles across all accessions. On average, each locus displayed 8.83 alleles, observed expected heterozygosity values 0.30 0.36, respectively. Gene PIC were recorded 0.37 0.35. The percentage loci varied significantly among groups, ranging from 8.00% to 82.40%, indicating high accessions (82.4%), moderate varieties (31.20%) landraces (29.60%), limited types (8.00).

Abstract Sesame is one of the world’s oldest oil seed crops grown mainly for its seeds. Lengthened storage time, inappropriate staking, back warded threshing method and poor facilities are major causes postharvest quality losses sesame seed. Therefore, objective was to review effect time conditions on longevity. Seed longevity mostly governed by moisture content, temperature, humidity, period, pre-storage conditions, pest infestations. Moisture content a pre-requisite long-term storage, most important factor affecting seeds remain consistent viable up 12 months under appropriate otherwise it get lessened viability. The crop should be harvested at stored 6% or lower content. In tropics where temperature as high 33 °C relative humidity about 80%, deteriorate rapidly. Varietal mixtures harvest affect in storage. Pests such as, Mites, Indian mealy moth, Weevils, Flour beetles, serious problems Under low insects may not problem. Oil require high-quality constructions prevent leakages allow easy access bin sampling monitoring. well-constructed room/ware house maintain viability

ABSTRACT Limited information exists on the impact of current seed storage methods quality in Central Ethiopia. The study aimed to assess extent decline on‐farm stored chickpeas. Two hundred two farmers were identified using a multistage and purposive technique, samples collected from five districts. rounds at early March planting time September 2022. Seed tests, including physical purity, physiological quality, health conducted standard laboratory techniques for samples. In Round 1, results showed that mean moisture (SM, %), germination (SG, %) 94.9%, 10.7%, 83.8%, respectively. Moreover, about 95.5% 81.8% satisfied certified class D standards SM SG, However, 2, met SG dropped 36.9% 63.1%, infection varied between 12% 80%, whereas 25% 100%. During both sampling, no sample fulfilled specified chickpea (%). Overall, was considerably lower during compared storage. challenges maintaining production, storage, management practices indicating need improve processing, handling enhance farm‐level productivity.

Sesame ( Sesamum indicum L.) is a crucial oilseed crop, valued for its nutritional qualities and resilience to environmental stress. However, as drought global temperatures increase, sesame cultivation increasingly threatened. While seeds are widely consumed in African Asian countries, few studies explore the impact on seed composition, focusing instead oil. This study addresses this gap by evaluating profiles of from 11 M 4 mutants their wild-type parents, cultivated under field water deficit conditions (50 % control irrigation) at two distinct locations, Taoujdate Afourare, Morocco, 2021. Targeted traits include moisture, ash content, oil total polyphenols, anthocyanins, flavonoids, amino acids, antioxidant activity. Data analysis revealed that specific responded favorably deficit, with increased levels activity, moisture. Notably, mutant ML2-68 showed high content (9.53 %) stability, ideal diverse environments. ML2-72 maintained (49.05 %), acids (14.46 mg GlyE/g), anthocyanins (4.51 mg/g), moisture (5.08 while US2-6 excelled phenolic compound (25.13 mg/g) accumulation free radical scavenging (96.09 suggesting health benefits. These results position genotypes ML2-68, ML2-72, US2-7, promising enhancing crop nutrition stability challenging environments, supporting efforts develop drought-resilient varieties.
