“…Plant characters such as the growth habit, branching pattern, stem pigmentation and days to maturity have been widely used to characterize various cultivars and accessions of groundnuts (Singh and Simpson, 1994). In aroids for example, a number of varieties and even species have been identified based on morphological characters (Karikari, 1971;Opoku-Agyeman et al, 2004). There is the urgent need for germplasm collection and characterization to bring to light the available gene pool to aid breeding.…”

Twelve landraces of kersting's groundnut (Kerstingiella geocarpa Harms), collected from northern Ghana in 2004 were evaluated for plant height, canopy spread, leaf area index, nodule count, days to 50% flowering, fresh and dry shoot weight, fresh and dry root weight, pod number per plant, grain yield and hundred seed weight. The following parameters were similar (p > 0.05) among the landraces: leaf area index, nodule count at 7 and 9 WAP, dry shoot weight at 7 WAP, fresh and dry shoot weight at 7 WAP, number of pods per plant and hundred seed weight. Plant height at 8 WAP significantly varied (p = 0.026) among the landraces. The landraces Boli, Heng milk mottled, Gbangu, Nakori and Puffeon produced the tallest plants. Canopy spread of Heng red mottled, Heng milk mottled, Boli, Nakori, Nankpaduri, Puffeon and Gbangu exceeded other entries at 9 WAP. Days to 50% flowering varied significantly (p = 0.001) among landraces with Puffeon, Gbangu, Heng milk mottled, Nakori and Heng red mottled flowering early. At 7 WAP, fresh shoot weight was significantly (p = 0.002) different among the landraces with Heng milk mottled, Funsi, Nankpaduri, Boli, Sigiri, Dugulatuk, and Gbangu outstanding. Grain yield was highly significant (p = 0.001) with Heng red mottled, Funsi, Puffeon, and Sigiri as best yielders. Six Principal components (PC) were significantly informative in a factor analysis. The PC1 contained 90.76% of the total variation in the collection. A cluster analysis revealed that the measured traits accounted for only 12% of the variation with two major clusters.

“…This was then followed with an evaluation of the susceptibility of local and exotic varieties to the root rot complex disease (Karikari, ). Similar individual studies were also carried out (Offei, Asante, & Danquah, ; Opoku‐agyeman et al., ; Safo‐Kantanka & Adofo, ; Tortoe & Clerk, ) but with an absence of a common front to purposefully enhance the growth and performance of cocoyam (Quaye et al., ; Ramanatha et al., ).…”

“…In spite of its high productivity levels and better storability compared to other tropical root and tuber crops (Opara, ; Opoku‐agyeman, Bennet‐Lartey, & Markwei, ; Quaye, Adofo, & Nimoh, ; Ramanatha et al., ), Xanthosoma sagittifolium has been marginalized in agricultural policies and research interventions on root and tuber crops. It remains an underexploited food resource (Falade & Okafor, ; Onyeka, ), with a reported decline of production levels in Ghana and Cameroon (Onokpise et al., ; Onyeka, ).…”

The critical role of indigenous crops in the socioeconomic growth of developing nations has necessitated calls for accelerated exploitation of staples. Cocoyam, Xanthosoma sagittifolium, is food for over 400 million people worldwide and is the most consumed aroid in West Africa. However, it remains an underexploited food resource. This study reviews existing literature and also makes use of primary data from interviews with indigenous cocoyam farmers, processors, consumers, and cocoyam scientists in the research Institutes of Ghana, to provide insight into existing nomenclature of the species, indigenous knowledge on food uses, nutritional value, and potential novel food applications of cocoyam. Adaptable technologies in conformity to new trends in food science that could be employed for in‐depth molecular studies and further exploitation of the crop are also discussed. It is envisaged that the provided information would contribute to global efforts aimed at exploiting the full potential of indigenous crops for sustainable food and nutrition security.

“…Cocoyam ( Xanthosoma sagittifolium ) is a root crop widely cultivated in tropical and sub‐tropical countries with annual production level of 10 million metric tonnes . Cocoyam is acclaimed for its use as an emergency crop during lean seasons of other staples and it is of great importance to the food chain of West and Central Africa . Ghana is the fourth largest world producer of cocoyam, having two commercial varieties, the red and white .…”

Water-Starch Interactions of Red and White Cocoyam (Xanthosoma sagittifolium )

et al. 2018

This study investigates the water–starch characteristics of two cocoyam varieties, red (mankanikɔkɔɔ) and white (mankanifufuo), alongside their relevant physicochemical and pasting properties. Differences between the varieties in their starch content, as well as amylose/amylopectin ratios are identified. Low‐field nuclear magnetic resonance (LF‐NMR) transverse relaxation time analysis of flour and starch suspensions of the two cocoyam varieties indicates changes in their gelatinization and retrogradation during heating and cooling. One to two water populations are identified for both varieties and are highly dependent on the temperature and concentration rather than the variety, however, the red variety showed higher retrogradation tendency. An increase in relaxation times at 75–80 °C is observed for flours and starches corresponding well to the amylograph pasting temperatures revealed using the Rapid Visco Analyzer.
