Farmer participatory evaluation of four hybrid water yam clones in the yam belt of Nigeria
Four hybrid water yam (Dioscorea alata) genotypes (TDa 00/00194, TDa 00/00103, TDa 00/00104, TDa 00/00363) with two superior landraces (TDa 92-2 and UM 680) were evaluated for high and stable yields, pest and disease resistance, and acceptable food and market qualities in 2006 using th...

| description | Four hybrid water yam (Dioscorea alata) genotypes (TDa 00/00194, TDa 00/00103, TDa 00/00104, TDa 00/00363) with two superior landraces (TDa 92-2 and UM 680) were evaluated for high and stable yields, pest and disease resistance, and acceptable food and market qualities in 2006 using the farmer participatory (FP) approach. This researcher managed trial was carried out in Umudike (humid forest), Abakaliki and Nsukka (derived savanna), and Makurdi (southern Guinea savanna). Farmers participated in evaluating the genotypes for physiological attributes, yield, and eating qualities during mid-season (August/September) and at harvest. The hybrid yams gave almost twice the tuber yield of the landraces. Also the landraces were scored higher than the landraces in terms of pest and disease resistance, plant canopy, leaf litter, etc. In terms of food quality, TDa 00/00194 (4.0) was rated a little higher than the local best UM 680 (3.9) though this did not differ from TDa 00/00104 (3.5). Results from sensory evaluation and palatability tests showed that TDa 00/00194 and TDa 00/00364 had the highest rating in food quality for amala preparation. In selecting water yams therefore, consideration should be based on sensory acceptance, high dry matter, and low peel loss. |

Quatre hybrides génotypes d’igname, l’eau yam (Dioscorea alata) (TDa 00/00194, TDa 00/00103, TDa 00/00104, TDa 00/00363 avec deux variétés supérieurs de races- une variété qui tolère l’effort biotique et abiotique ayant pour le résultat la stabilité élevée de rendement (TDa 92-2 et UM 680) ont été évalués pour les rendements élevés et durable, la résistance aux ravageurs et de la maladie et les qualités acceptables de nourritures et du marché en 2006 utilisant l’approche participatives de fermier et vulgarisation (FPE). Cette chercheurs gérés essais a été effectuée dans Umudike (forêt humide), Abakaliki et Nsukka (la savane dérivée) et Makurdi (Sud de la Guinée de Savane). Les fermiers ont participé à évaluer les génotypes pour les attributs physiologiques, le rendement et les qualités consommables pendant la demi saison (août/septembre) et à la récolte. Les hybrides d’igname ont donné presque deux fois le rendement de tubercule des variétés locales. Également les hybrides ont été marqués plus élevées que des variétés locales en termes des résistances aux ravageurs et de la maladie, plante abris et les feuilles mortes etc. Sur le plan de qualité des produits alimentaires, TDa 00/00194 (4.0) ont été évaluées d’avoir une meilleure qualité en comparaison du meilleure de variété locale UM680 (3.9) bien que ceci n’ait pas différé de TDa 00/00104 (3.5). Le résultat d’évaluation sensorielle et l’acceptation de goût ont prouvé que TDa 00/00194 et TDa 00/00364 ont eu l’estimation la plus élevée de la qualité des produits alimentaires pour la préparation d’amala. En choisissant l’eau yam donc, la considération devrait être basée sur l’acceptation sensorielle, la matière sèche élevée et une perte réduite d’épluchure. 2009 2018-02-06T12:14:51Z 2018-02-06T12:14:51Z Conference Paper https://hdl.handle.net/10568/90805 en fr Limited Access Ikeorgu, J.G., Oselebe, H., Oluwatayo, J., Ugwuoke, K., Ukpabi, U. & Asiedu, R.
