“…Singh et al [85] reported high variability among 859 taro accessions from Papua New Guinea using 10 quantitative and 20 qualitative traits. High morphological variability has also been reported among taro accessions from Southeast Asia and Oceania [86,87]. Similar agro-morphological variability was observed among 2,298 taro accessions collected within the TaroGen project [88].…”

Taro is an ancient nutritional and medicinal crop woven into the fabric of the socio-economic life of those living in the tropics and sub-tropics. However, West Africa (WA), which has been a major producer of the crop for several decades, is experiencing a significant decline in production as a result of taro leaf blight (TLB), a disease caused by Phytophthora colocasiae Raciborski. A lack of research on taro in WA means that available innovative technologies have not been fully utilized to provide solutions to inherent challenges and enhance the status of the crop. Improvement through plant breeding remains the most economically and environmentally sustainable means of increasing the productivity of taro in WA. With this review, we provide insights into the importance of the taro crop in WA, evaluate taro research to date, and suggest how to address research gaps in order to promote taro sustainability in the region.

“…Similarly, Bhattacharjee et al reported wide degree of variation in leaf colour and shape corm weight and number of petiole per plant existed among different selected genotypes in India indicating greater possibility of improvement through selection [28]. Such quantitative and qualitative morphological variation might contribute desirable character that has to be included in breeding for further improvement of the crop.…”

Germplasm screening, characterization and genetic improvement activities play great role in production and productivity of crops. Crop genetic evaluation can be conducted by morphological or molecular techniques and the available result has wide application in agriculture. Beside, appropriate breeding methods help to develop desirable plant character for further utilization depending on the identified gaps. Better understanding of crop genetic characteristics and breeding methods are useful in germplasm collection, conservation and utilization particularly in case of root and tuber crops. Different scientific findings on taro genetic characterization and breeding achievements were reviewed in this paper for further understanding and information dissemination. It was characterized largely based on morphological characters and few on molecular techniques and in both presence of variability that can be used in improvement programs was reported. Classical and modern taro breeding approaches utilized resulted in high yielding variety, disease resistant variety and drought resistant cultivar.

“…Many researchers have also reported the presence of high variability in the taro using morphological markers [16]. Corm color, corm shape, corm size, petiole length, number of petioles, petiole color, corm flesh color, leaf color, leaf shape, corm weight, stolon formation [17][18][19], and flower formation [20] are just a few of the morphological markers.…”

Malnutrition afflicts a large number of people in Sub-Saharan Africa. Orphan crops, such as Taro plants, can play critical roles in ensuring global food and nutritional security in this regard. Nigeria is the world's leading producer of taro. It is primarily consumed as a main component or as a soup thickener by resource-poor rural residents in Nigeria's south-eastern regions. The corm contains a lot of carbohydrates, while the leaves have a lot of protein. Furthermore, its social and medicinal importance should not be overlooked. It is, however, a food resource that is underutilized and receives little attention from scientists. Farmers cultivate it on a small scale, and its commercial importance is primarily limited to the local area, implying that farmers are the primary users and keepers of taro genetic diversity. As a result, they've gained some valuable experience in identifying and preserving cultivars they prefer, as well as developing utilization patterns (culinary diversity) for the cultivars they've kept. Information on farmers' knowledge of taro utilization patterns, cultivar maintenance, and culinary diversity is scarce in Nigeria, particularly in the south-eastern region. The purpose of this study is to review existing literature on farmers' and consumers' perceptions and preferences for taro in order to provide insight into knowledge of taro food use, benefits, and potential brand foods. It also addresses key bottlenecks that impede taro production and consumption in Nigeria, paving the way for increased taro production and adoption by both farmers and consumers.
