“…Taro viruses, which could lead to diseases, damage the crop yield and sometimes lead to plant death [17]. Multiple viruses have been found to infect taro, including the four main viruses; Dasheen mosaic virus (DsMV) , Taro bacilliform virus (TaBV) , Colocasia bobone disease virus (CBDV) , and Taro vein chlorosis virus (TaVCV) [5,6,8,9,17,18,19,20,21,22,23,24,25,26] that this review will centre on. This review will also mention a relatively new virus Taro bacilliform CH virus (TaBCHV) [17,19,27].…”

Taro is an important crop in parts of the world, especially in the Pacific Islands. Like all plants, it is also susceptible to virus infections that could result in diseases, which negatively affects the source of food and trade revenue. Understanding the biology of taro viruses could improve current knowledge regarding the relationship between viruses and taro, thus allowing for a better approach towards the management of the diseases that are associated with them. By compiling and discussing the research on taro and its four major viruses (Dasheen mosaic virus, Taro bacilliform virus, Colocasia bobone disease virus, and Taro vein chlorosis virus) and a relatively new one (Taro bacilliform CH virus), this paper explores the details of each virus by examining their characteristics and highlighting information that could be used to mitigate taro infections and disease management.

“…An alternative explanation is that DsMV has recently spread to traditional Maori taro cultivars from imported taro or other hosts such as Zantedeschia. Comparison of three DsMV isolates from different sources by Matthews et al (1996) found differences in serological reaction between isolates. Further analysis of the isolates from taro in New Zealand may provide clues to their origin.…”

“…With the high cost of imported taro, interest in growing taro in New Zealand, especially cultivars more suited to a temperate climate, has been revived (Scheffer 1995;Follett & Scheffer 1996). Dasheen mosaic potyvirus (DsMV) has previously been recorded from Zandedeschia in New Zealand (Matthews et al 1996) but there appear to be no published records of DsMV infecting taro. This research note reports the serological identification of DsMV from two experimental taro crops in the Auckland region of New Zealand.…”

“…Dasheen mosaic virus (DMV) is associated with all edible aroids and the use of vegetative means of propagation has contributed significantly to the worldwide distribution of the virus (Yam et al, 1990;Asokan et al, 1984;Valverde et al, 1997). Other viruses are known to infect members of the genus, but DMV is the most widespread and prevalent (Matthews et al, 1996). Ramírez (1985) reported that DMV infections occurs in at least 80% of all commercial plantations in Costa Rica, however, no reports on its incidence in Nicaraguan cocoyam plantations have so far been published.…”

Agronomic performance of three cocoyam (Xanthosoma violaceum Schott) genotypes grown in Nicaragua

2005

Cocoyam (Xanthosoma spp.), the third most important starch food crop in Nicaragua, can be cultivated countrywide. However, very little information about the field performance and genetic background of the different genotypes is available. In this study, the agronomic performance of three purple genotypes established in four locations with different climatic conditions, were evaluated during 2 years. Phenotypic characteristics, yield, and virus incidence were assessed and the time at which the different genotypes reached their physiological maturity was estimated. The trials were based on randomized complete block design with three or four blocks. Genotype × location interaction was found both for phenotypic and yield traits. A differential response of the genotypes to the varying climatic conditions at the locations is suggested to be one of the causes to the interaction. The unpredictable and variable climate in the area where cocoyam traditionally has been grown is one possible explanation to the frequent genotype × year interaction at that location. Other locations with more stable climate only showed an interaction between genotype and year in a few traits. The genotypic differences regarding the time when the area of the largest leaf reached its maximum and the variation in presence of sprouts and roots on the cormels at harvest, indicate differences in optimal harvest time between genotypes. The percentage of plants infected with dasheen mosaic virus (DMV) differed across locations but not between genotypes.
