One hundred and thirty six sweet potato (Ipomoea batatas) landraces collected from three different agro-ecological Zones of Tanzania [Lake Victoria basin (LZ), Eastern (EZ) and Southern Highlands Zones (SHZ)] were characterized morphologically and agronomically using International Potato Centre (CIP) descriptors in two seasons. The cluster analysis revealed existence of two major groups, 1 and 2 with low genetic variability of 0.52. Number of roots, weight of roots, fresh weight/plant and dry…

Phenotypic profiles of different accessions of sweet potato (Ipomoea batatas L. Lam) in the coastal savanna agro-ecological zone of Ghana
TLDR
The exotic accession (US 020) recorded the highest total root yield and harvest index, indicating its superiority over the local accessions, and high genetic variability among the 20 accessions based on the agromorphological and yield characteristics.
Agronomic Characterization of 88 Accessions of the Sweet Potato (Ipomoea batatas (L.) Lam.) Collection of Côte d'Ivoire
The characterization of genetic resources is essential for improvement and conservation programs. The objective of this study was to study the morphological and agronomic variability of the sweet
Agronomic and Physicochemical Evaluation of Sweet Potato [Ipomoeabatatas (L.) Lam.] Collections in Ethiopia
TLDR
This study conducted during 2012/2013 cropping season to characterize, evaluate, and documenting of agronomic and physicochemical attributes of sweet potato accessions at Haramaya University recorded significantly higher values than mean of the checks.
Principal Component Analysis for Phenotypic Characterization of Sweet Potato (Ipomoea batatas (L.) Lam.) Genotypes in Malaysia
A total of 39 sweet potato genotypes (Ipomoea batatas (L.) Lam.) were grown at Malaysia Agricultural Research and Development Institute (MARDI), Industrial Crop Research Centre, in Bachok, Kelantan.
Morpho-agronomical characterisation of local and international sweetpotato germplasm from the South African collection
TLDR
The phenotypic diversity of South African sweetpotato collections is determined using morpho-agronomical characteristics to complement data on protein content of the accessions towards breeding for improved nutritional content.
Genetic Fingerprinting of Sweet Potato [ Ipomoea batatas (L.) Lam ] as Revealed by Isozyme Electrophoresis Analysis
TLDR
Two of the four isozyme markers examined, Aspartate amino transferase (AAT) and 6-phosphogluconate dehydrogenase (6 PGD) were more effective to discriminate sweet potato genotypes, and morphological data revealed three distinctive clusters.
Morphological Characterization of Leaf and Flower of Local Sweet Potato [Ipomea batatas L.] From Agam and Solok District, West Sumatra Province
TLDR
Information on genetic diversity and the pattern of relations between accessions will be very useful for the West Sumatra people in developing superior sweet potatoes.
Evaluation of Sweet Potato [Ipomoea Batatas (L.) Lam.] Accessions for their Physicochemical Attributes in Ethiopia
TLDR
Estimation of physicochemical attributes of sweet potato accessions in Ethiopia showed that presence of variations among accessions for traits studied and the possibility of selecting accession for further testing for different breeding objectives.

Genetic diversity in sweetpotato [Ipomoea batatas (L.) Lam.] in relationship to geographic sources as assessed with RAPD markers
TLDR
The reported hypothesis of the origin and dispersal of the sweetpotato is supported and indications that new genepools may be evolving in Africa and Asia due to hybridisation and adaptation to the local environments are indicated.
Molecular Resolution of Genetic Variability of Major Sweetpotato Viruses and Improved Diagnosis of Potyviruses Co-infecting Sweetpotato
TLDR
Using findings of molecular resolutions of major viruses in East Africa and Australia, a simple and sensitive RT-PCR/RFLP based diagnostic procedure was devised to differentiate potyviruses in complexes which readily differentiated SPVY and strains C and RC of SPFMV.
