LITERATURE REVIEW ON COCOYAM

One of the lessons of the Papua New Guinea breeding program was the difficulty of getting rid of wild deleterious traits. Apart from that it can help to prevent certain conditions like excess gas, cramping, bloating, constipation and even diarrhea. The first descriptor list for Taro, developed by international board for plant genetic resources was used in earlier attempts to characterize germplasm [ ]. Taro is a plant that must be tilled and watered if it is to grow and perform. Optimization of QTL detection through the use of large populations of progenies as well as trial replications is important and critical when low heritability traits are considered. Combining genotypes from the two major genepools is strategic towards establishing a broad base for any breeding programme.

Breeding programs of Taro were initiated in late s with varietal releases recorded in Fiji in , Samoa in and , Solomon Islands in and , Papua New Guinea in and India in [ 78 , 79 ]. Progenies of Tannia grown from true seed in the first filial generation showed considerable variation. Optimum fertilizer application raised the yield from In trials with Colocasia dasheen type , placing corms in a medium of rice hull ash extended its usual storage life of corms by 14 days and reduced the incidence of decay Quevedo et al. This practice has been predominantly adopted in Papua New Guinea and Samoa.

Towards an Enhanced Breeding in Cocoyam: A Review of Past and Future Research Perspectives

It was observed that for all the antinutrients studied, cookies from Results obtained for the physical properties of the cookies are shown in Table 4. Good shock and vibration absorbers and careful driving will assist in reducing the incidence of damage. Cocoyam are herbaceous perennial plants belonging to the family araceae and are grown primarily of their edible roots, although all parts of the plant are edible.

Gelatinization of starch and wheat flour starch-a review. In the past, it is teview as a lowly important crop which cultivation and consumption lie within the less privileged farmers. In Brazil, detoxified manioc is ground and cooked to a dry, often hard or crunchy meal known as farofa used as a condiment, toasted in butter, or eaten alone as a side dish. In addition, they also contain greater amounts of vitamin B-complex than whole milk and can be useful to people allergic to cereals and can be consumed by children revies are sensitive to milk thus its use in infant food formulae [ 15 ].

literature review on cocoyam

Literature review on cocoyam flourreview Rating: Prolonging the life span of cocoyam pollen through storage can assist plant breeders to effect artificial pollination. It contains dietary fibre and higher protein contents than the majority of the tropical root crops.

These traditional storage conditions reduce rfview loss and promote the curing of wounds. Mature tannia corms do not deteriorate if left in the ground and it is also common practice to harvest corms for immediate utilization as required.

Selection of cassava species to be grown, therefore, is quite important. This oil will also make your hair look healthier and fresher. The breeding of cultivars is a complex process which requires experience, adequate genetic resources, and reliable data loterature inheritance of crucial agronomic traits.

literature review on cocoyam

Analysis of the economic costs of using taro in broiler rations in the Philippines showed that the use of taro meals at It has been reported that of all the solid nutrients present in roots and tubers like cocoyamcarbohydrates predominate [26]. However, resulted in a significant reduction in starch content and increase in total sugar content.

The large roots are peeled cocoyam then ground into flour, which is then soaked in water, squeezed dry several times, and floured. It produces heart shaped leaves ‘ long and ‘ across on 3’ long petioles that all emanate from an upright tuberous rootstock, called a corm. Harvesting is carried out by lifting the corms by hand. Accessed 5 Mar Spencer stated that taro and other edible arioida were distributed from east India to Formosa and the Solomon Islands.

Cassava flours, peels and leaves revlew not be consumed raw because they contain two cyanogenic glucosideslinamarin and lotaustralin. The Pro-Gibb Plus foliar spray proved to be more effective than pre-plant soak with the same material in reference to number and vigour of the inflorescences produced, duration of flowering and the percentage of plants that flowered [ 37 ].

Poor farm management and husbanding practices especially inappropriate plant cocoyam and very limited literayure use.

THE PROBLEM AND PROSPECTS OF COCOYAM PRODUCTION Agriculture Project T

Post-harvest rots and decay of stored corms is a problem in edible aroids and can be caused by representatives of all the major taxonomic groups Cooke et al. Nigeria cassava starch in considered to be of low quality by Nigerian industries and none is floured. The study therefore seeks to examine and appraise the problems and prospects of cocoyam production in our society, a case study of Ovia North East Local Government Area.

Due to the challenges of seed propagation fertile seeds rarely develop [ 41 ]. Progeny selection in a breeding scheme depends on the objectives of the breeding programme. Due to higher yield and better produce prices, Fanteakwa literatufe have a competitive advantage over other producing districts.

An intuitive approach latter formed its own canopy.

International germplasm exchange as envisioned in reivew international projects play an important role in broadening genetic diversity. Cassava can be a powerful poverty fighter in Africa.
