Providing safe and secure food for an increasing number of people globally is challenging. Coping with such a human population by merely applying the conventional agricultural production system has not proved to be agro-ecologically friendly; nor it sustainable. Cowpea ( Vigna unguiculata (L) Walp) multi-purpose legume. It consists high-quality protein consumption, rich in livestock fodder. enriches soil that recycles nutrients through fixation nitrogen association nodulating bacteria. However, productivity this multi-functional, indigenous legume great value African smallholder farmers rural populace, also urban consumers entrepreneurs, limited. Because cowpea strategic importance Africa, there need improve on its productivity. Such endeavors Africa are wrought challenges include drought, salinity, excessive demand among synthetic chemicals, repercussions climate change, declining nutrients, microbial infestations, pest issues, so forth.

Legumes play a significant role in food and nutritional security contribute to environmental sustainability. Although legumes are highly beneficial crops, it has not yet been possible enhance their yield production satisfactory level. Amid rising population low levels, per capita average legume consumption India fallen by 71% over the last 50 years, this led protein-related malnutrition large segment of Indian population, especially women children. Several factors have hindered attempts achieve enhancement grain legumes, including biotic abiotic pressures, lack good ideotypes, less amenability mechanization, poorer responsiveness fertilizer input, poor genetic base. Therefore, there is need mine approximately 0.4 million ex situ collections that being conserved gene banks globally for identification ideal donors various traits. The National Gene Bank conserves 63,000 accessions belonging 61 species. Recent initiatives undertaken consortia mode with aim unlocking potential conducting large-scale germplasm characterization evaluation analyses. We assume phenotyping integrated omics-based science will aid target traits use gains. Additionally, cases where base major narrow, wild relatives evaluated, these exploited through pre-breeding.

The assessment of genetic diversity and structure a gene pool is prerequisite for efficient organization, conservation, utilization crop improvement. This study evaluated the population 24 Tunisian melon accessions, by using phenotypic traits eight microsatellite (SSR) markers. A considerable among accessions was observed many characters including those related to agronomical performance. All microsatellites were polymorphic detected 30 distinct alleles with moderate (0.43) information content. Shannon’s index (0.82) showed high degree polymorphism between genotypes. heterozygosity (0.10) less than expected (0.12), displaying deficit in because selection pressure. Molecular clustering analyses based on SSRs separated into five groups an intermixed landraces breeding lines belonging different botanical groups. Phenotypic two main clusters sweet non-sweet melon; however, more precise inodorus, cantalupensis, reticulatus subgroups obtained combined phenotypic–molecular data. discordance molecular data confirmed negative correlation (r = −0.16, p 0.06) as revealed Mantel test. Despite these differences, both markers provided important about germplasm, allowing correct use future programs. Together they provide powerful tool agricultural conservation tasks.

Nanhaia speciosa is a valuable industrial crop known for its significant edible and medicinal properties, attributed to abundance of secondary metabolites. This study aims elucidate the genetic relationships among N. speciosa, enhance species identification accuracy, select genetically stable, high-quality germplasms speciosa. To achieve this, we conducted chloroplast gene amplification sequencing, alongside an analysis agronomic traits 19 germplasms. Additionally, non-targeted metabolomic profiling using UPLC-Q-Orbitrap/MS chemometric methods was employed assess their metabolic diversity relationships. The results revealed notable differences in DNA barcodes structures across germplasms, with atpF-atpH sequence successfully distinguishing all into distinct varieties. Multivariate statistical analyses, including principal component (PCA), partial least squares discriminant (PLS-DA), hierarchical clustering, identified 12 key marker metabolites that effectively differentiated consistent observed phenotypic diversity. A clustering integrating genetic, phenotypic, data further validated utility barcoding identification. comprehensive showed NDL-2 NDL-18 exhibited relatively good while NDL-1 NDL-19 poor properties. provides crucial insights breeding improvement related species, offering reference identification, conservation, utilization germplasm resources within

Introduction This study focuses on cowpea, a vital crop for smallholder farmers in sub-Saharan Africa, particularly Malawi. The research aimed to understand the genetic diversity and population structure of cowpea perform genome-wide association studies (GWAS) identify marker-trait associations (MTAs) yield related traits. These insights are intended support varietal development address agricultural challenges Methods A total 306 genotypes were characterized using single nucleotide polymorphism (SNP) markers morphological assessed effects genotype, location, their interactions Fixed Random Model Circulating Probability Unification (FarmCPU) algorithm was used significant MTAs. Results traits showed interaction effects. Genotypes MWcp24, MWcp47, MWcp2232, TVu-3524 yielded highest values. Grain positively correlated with peduncle length, seeds per pod, pods plant. Three distinct clusters identified based Genetic analysis revealed an average minor allele frequency 0.31, observed heterozygosity 0.06, gene 0.33. inbreeding coefficient 0.82, indicating high level inbreeding.

Cowpea ( Vigna unguiculata L.) is an underutilised vegetable legume indigenous to and predominantly cultivated consumed in Africa. However, its reach agricultural production consumption has expanded globally. This resilient crop known for ability withstand various environmental stressors, making it suitable marginal systems commonly used by small-scale farmers. Although cowpea exhibits tolerance drought, notably sensitive salinity stress biotic agents. The degree of drought varies among different cultivars, which requires further research develop more varieties.The changing climate patterns associated uncertainties highlight the urgent need breed productive cultivars. Conventional plant breeding techniques have produced new varieties cowpeas, yet limited genetic diversity within cowpeas poses challenges future conventional efforts. New (NBTs), including gene editing tools, single base pair alterations, DNA methylation methods, offer promising alternatives accelerate improvement. such approaches are also faced with success organogenesis (OG) somatic embryogenesis (SE) tissue culture. review examines advances use culture enhance productivity resilience against abiotic stresses.
