“…Within the Pacific region, the findings of Yen and Wheeler (1968) regarding the distribution of these forms, particularly the representatives in tropical Polynesia and Papua New Guinea as exclusively 2n=28, have not been contradicted. On numerical data alone, however, the recent record of the triploid from on the Solomon Islands (Jackson et al 1977) gives impetus to the question of provenience of the New Zealand forms of 2n=42. Explanations of direct transmission in prehistory from Melanesia to New Zealand are generally unacceptable on cultural grounds, so that the alternatives remain of introduction in historic times as Yen and Wheeler (1968) proffered, or that 42 chromosome forms arose independently in the Pacific from 28-forms.…”

“…Meristems have proved to be the most suitable explants for somatic embryogenesis in many plant species [11]. Abo El-Nil and Zettler [1] and Jackson et al [8] used shoot-tips and meristems to initiate taro tissue culture. First callus formation and indirect plantlet development from axillary meristems of taro was reported by Yam et al [28,29].…”

This is a first report on direct somatic embryogenesis and organogenesis of taro (Colocasia esculenta var. esculenta) using axillary meristem explants. Best somatic embryogenesis was observed in cultures that were established on Murashige and Skoog (1962) (MS medium) containing 10 µM 2, 4-dichlorophenoxyacetic acid (2, 4-D) and 2 µM thidiazuron (TDZ) and then transferred on medium with 5 µM TDZ. MS medium containing 3 µM gibberellic acid (GA) and 4.5% sucrose proved best for inducing germination in somatic embryos which converted into 20.0 ± 3.46 complete plantlets per embryo cluster per explant on ½ strength MS basal salts with 1% sucrose. Best organogenesis was observed in cultures that were established on MS medium containing 2 µM TDZ and then transferred on medium with 5 µM TDZ. Subsequent transfer of these cultures on MS medium with 5 µM indole-3-acetic acid (IAA) and 7.5 µM 6-benzylaminopurine (BAP) resulted in maximum shoot multiplication. MS medium containing 2 µM IAA proved best for inducing rooting in multiplied shoots. Both direct somatic embryogenesis and organogenesis resulted in mass and rapid production of taro plantlets which were acclimatized and field transferred. Vigorous plant growth and healthy corm production was observed in the field. This in vitro propagation method of taro through direct somatic embryogenesis and organogenesis is significantly reliable over prevailing methods available for other cultivars and provides sustainable means of quality taro production in the Pacific and the Caribbean region where non-availability of elite seedlings is a limiting issue.

“…However, viable seed production depends on the availability and compatibility of resistant germplasms as well as the vagaries of weather and pests and diseases [19]. Several researchers have reported on the production of improved taro cultivars through tissue culture [20][21]. Similarly, de novo regeneration in taro has also been reported and documented [22][23].…”

During the past years, precisely [1965][1966][1967][1968][1969][1970][1971][1972][1973][1974][1975][1976][1977][1978][1979][1980], yam and taro reigned supreme in the Southern parts of Nigeria. Yam was the king and taro the queen. They were then the staple food of choice and were even offered to the gods. Their acceptance and ascendancy were challenged by the arrival and domestication of the easy growers (plantain, banana, maize and later cassava, tannia and sweet potato). The easy growers gained recognition and prominence as staple foods and subsequently replaced the earlier staples. Thus, cassava and sweet potato superseded yam and taro respectively. Nutritionally, taro has broader compliments of vitamins and nutrients compared to other root and tuber crops. The domestication of the new crops which are relatively more yielding and at the same time enjoys international leverage in research and development pose enormous challenges for the future of taro as a major crop. Strategic options for increase in taro production and consumption should be on consumer education and on its nutritional and health benefits. Increased attention on taro research will provoke a better understanding and contributions the crop can offer in the areas of food security, health and economic empowerment. The paper now reviews some of the nutritional and medicinal benefits of taro. Its contributions as an industrial crop will also be highlighted with special emphasis on the challenges facing taro crop cultivation in Nigeria and the possible approaches to enhance its sustainable production.
