“…The development of an economically profitable production of any plant species like S. radiatum undoubtedly requires the use of improved high yielding varieties. To facilitate breeding efforts, characterisation of available germplasm is a necessary first step since it especially, benefits a plant breeder in choosing proper parental materials (Cilliers and Swanevelder, 2003;Sarutayophat et al, 2007). Also, the knowledge about interrelationships among descriptors (characteristics), from a plant breeder"s perspective aid in the selection of superior genotypes from the breeding population and is important in planning and evaluating breeding programmes (Sheela and Gopalan, 2006).…”

Sesamum radiatum (Schum. and Thonn) is a traditional leafy vegetable of national importance in Benin. Although, it is cultivated and consumed in many regions of the country, it is still unfortunately neglected by scientific research. In order to fill in the knowledge gaps necessary for its varietal improvement, 16 accessions collected from different agro-ecological zones were characterized using 16 quantitative morphological traits. A significant variability was found among the accessions. Day to flowering, day to fruiting, total biomass, plant height, noose diameter, number of fruits per plant and number of seeds per fruit were some of the most discriminating parameters. Multivariate analysis (principal component analysis and cluster analysis) revealed four distinct agro-morphological groups of varying performance which will be highly useful in varietal improvement. Correlation analyses between descriptors revealed uniquely desired positive and negative relationships hence, indicating predictable success for eventual breeding program. To further investigate the genetic basis of the phenotypic diversity revealed among S. radiatum accessions, the use of molecular markers such as amplified fragment length polymorphisms (AFLPs) is recommended.

“…Some genetic resources developed by the International Crops Research Institute for Semi-Arid Tropics (ICRISAT) such as ICGV 87084, ICGV 87094, and ICGV 87110 are reportedly resistant to A. flavus. Furthermore, 12 groundnut accessions with resistance to aflatoxin are developed by the Agricultural Research Council in South Africa (Cilliers and Swanevelder 2003). Improved Spanish groundnut cultivars such as ICGV 91278, ICGV 91283, and ICGV 91284 were selected by ICRISAT showing considerable resistance for aflatoxin-producing fungus (Upadhyaya et al, 2001b).…”

“…In most cases, groundnut genetic resource held in various genebanks are available for research and breeding purposes subject to the signing of material transfer agreement. For example, in South Africa, almost all groundnut genetic resource held by the Agricultural Research Council are available on request (Cilliers and Swanevelder 2003). Groundnut genetic resource held by ICRISAT are also available by interested scientists for scientific studies or breeding purposes (Upadhyaya et al 2001b).…”

Groundnut (Arachis hypogaea L.) is a multipurpose legume crop widely cultivated in sub-Saharan Africa (SSA). However, yield levels of the crop has remained relatively low in SSA owing to a range of biotic, abiotic and socioeconomic constraints. A dedicated groundnut improvement programme integrating new tools and methodologies to breed varieties suitable for current and emerging agro-ecologies and market needs is essential for enhanced and sustainable groundnut production in SSA. The objective of this review is to highlight breeding progress, opportunities and challenges on groundnut improvement with regard to cultivar development and deployment in SSA in order to guide future improvement of the crop. The review analysed the role of new tools in breeding such as, high-throughput and automated phenotyping techniques, rapid generation advancement, single seed descent approach, marker-assisted selection, genomic selection, next-generation sequencing, genetic engineering and genome editing for accelerated breeding and cultivar development of groundnut.

“…Diverse apple genetic resources avail opportunities to breeders to develop new and improved apple cultivars with desirable characteristics that encompass traits preferred by farmers such as yield potential and large fruits and those preferred by breeders such as pest and disease resistance and photosensitivity [19]. e knowledge that genetic diversity is the central pillar of biodiversity, diversity within species, between species, and of ecosystems, necessitates characterization of accessions to facilitate the making of proper choices of parental materials by breeders [19][20][21].…”

Worldwide, apple ranks fourth in terms of economic importance after citrus, grapes, and bananas with a world production of above 71 million tonnes per year. Apple accessions that are in cultivation throughout the world appear to have come from a genetically similar source. Their diversity has further been decreased through the use of preferred few accessions in breeding programmes. Determination of morphological diversity among the accessions maintained at Nyanga Experimental Station is key for identification and informed use of the accessions in adaptive research. The purpose of this study was to determine the extent of morphological diversity among apple accessions conserved at Nyanga Experimental Station, Zimbabwe, and identify promising accessions for use as cultivars in warmer environments. Sixty-eight Malus domestica accessions of worldwide provenance all maintained at Nyanga Experimental Station were evaluated in a complete randomized design with three replications. The experiment was managed following the standard cultural practices for apples. Characterization using morphological markers was done following the format of the International Board for Plant and Genetic Resources (IBPGR). Data were subjected to cluster analysis based on the unweighted paired group method using arithmetic averages (UPGMA) method. A narrow genetic diversity was observed as reflected by the pairwise genetic similarity matrix that ranged from 80 to 100%. Promising accessions such as Anna, Mayaan, Michal, Elah, Tydeman’s Early Worcester, Discovery, and Mollies Delicious were identified for use as cultivars in warmer areas.
