“…Since seasonal variability (years) was absent in the seven traits, means of the two years were used for analysis. The findings in this study are concomitant with what Mbithe et al (2016) found among 11 Ugandan sweet potatoes, where ANOVA analysis of 22 descriptors showed high variability of most morphological characters. High phenotypic variation among sweet potato genotypes has been variously demonstrated (Karuri et al, 2010;Maquia et al, 2013;Demelie and Aragaw, 2016).…”

“…Owing to relative ease of study and inexpensiveness, morphological characters have been variously used to characterize and differentiate sweet potato accessions, assess comparative reaction and susceptibility to pests, diseases and other stresses etc. (Yada et al, 2010;Elameen et al, 2011;Vimala et al, 2012;Norman et al, 2014;Rahman et al, 2015;Amoatey et al, 2016;Mbithe et al, 2016;Su et al, 2016). Therefore, this study was conducted to characterize existing local and introduced sweet potato accessions in order to evaluate phenotypic diversity for effective utilization in breeding programs.…”

Characterization of landraces is central to any conservation measures devised for sweet potato inMalawi. Studies were therefore conducted using seven morphological descriptors and farmers' indigenous knowledge systems (IKS) to investigate the phenotypical diversity of 286 landraces and 35 introductions of sweet potato from the north, south east and lower Shire. The accessions were planted in a check plot design at Bvumbwe Agricultural Research Station. The results showed that farmers' knowledge (IKS) is a means for preliminary characterization of accessions as evidenced by elimination of 75 duplicate accessions by 12 farmers. Analysis of variance (ANOVA) showed that all accessions and populations were phenotypically variable (p≤0.01) and Chi-square test of the morphological descriptors used in the study varied significantly among the three eco-geographical areas and among the landraces and introductions (p≤0.05 and p≤0.01), implying high variability of the accessions. However, the accessions clustered at 50% dissimilarity and generally irrespective of eco-geographical origin, signifying some similarity probably due to gene flow. Shannon Weaver Diversity Index (H') indicated that different traits had different source areas of highest diversity which were significantly different (p≤0.05); nonetheless Shire Valley had the highest mean diversity for all traits (H'=0.67) which was significantly different from the other two populations (p≤0.05) inferring that the lower shire would be ideal for in situ conservation of sweet potato diversity.

“…These correlations indicate the importance of sink-source relationships in plants. M.J. Mbithe et al [20] observed a similar relationship on sweet potato genotypes in Uganda.…”

“…However, most genotypes were not ideal in terms of root yield stability except for genotype Nyautenge. High yield is a product of genetic make up of individual genotypes [5,17], increased weight of roots, or increased number of roots, per plant [20]. There was a potential of some genotypes to yield more if all roots harvested from each plot would be equal to the largest root.…”

A main characteristic of sweet potato [Ipomoea batatas(L.) Lam.] is its high phenotypic and genotypic variability. There is no, or limited, information on suitability of agro-morphological characteristics for utilization in production and processing. Currrently, farmers are growing different sweet potato genotypes characterized with low yield. The aim of the study was to evaluate agro-morphological characteristics of 68 sweet potato genotypes in order to determine the best performing ones. The sweet potato genotypes were grown at the Kenya Agricultural and Livestock Research Organization and the Embu and Miyare Agriculture Training College. The locations were chosen because they are the main sweet potato producing areas with different climatic and production conditions. Six storage root and five aerial characters were used in the characterization. The genotypes differed in storage root stalk and root length; vine internode length and vine internode growth rate; petiole length and leaf size, and yield at both sites. Genotype Nyautenge was the best performing in terms of storage root yield. There was poor correlation among agro-morphological attributes. The study demonstrates the potential of some sweet potato genotypes such as Nyautenge for high productivity.
