Roots and Tubers for the 21st Century Trends, Projections, and Policy Options

Characterization of cocoyam Xanthosoma spp. The present study assessed the physical, chemical, functional, and microbiological properties of cocoyam Xanthosoma spp. The flour was initially submitted to a water-soaking process in order to reduce its high oxalate content. The soaked flour showed a high dietary fiber content The anti-nutritional component analysis showed low levels of oxalate 5.

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

Socioeconomic survey of traditional commercial production of cocoyam and cocoyam leaf. Cocoyam, Xanthosoma sagittifolium , is cultivated in tropical regions for human nutrition, animal feed, and cash income for both farmers and traders [1] , [2] , [3]. Cocoyam is vegetatively propagated using the corms and to a lesser extent the cormels. As food for human consumption, the nutritional value of the various parts of cocoyam is primarily caloric [4]. The underground cormels provide easily digested starch; and the leaves are nutritious spinach-like vegetable, which give a lot of minerals, vitamins and thiamine [5] , [6] , [7].

Cocoyam Xanthosoma sagittifolium L. Schott is an exotic species from tropical America that is widely cultivated in Ethiopia for its edible cormels and leaves. There is a dearth of information on the genetic diversity of Ethiopian cocoyam. In order to evaluate and select cocoyam germplasm for breeding and conservation, genetic diversity of Ethiopian cocoyam accessions 65 green- and 35 purple- cocoyam were analyzed using 29 morphological traits 16 qualitative and 13 quantitative and 12 SSR loci. Two classes of qualitative traits were observed. ANOVA revealed significant variation in 11

Cocoyams Taro and Tannia are important food crop in the tropical world. Beyond their food and nutritious values, they have cultural, religious and social meanings which vary within cultures. As with most tropical underutilized crops, cocoyam is affected by biotic and abiotic stresses resulting to low yield. In addition, limited genetic advancement in post-harvest and organoleptic properties is visible. While significant breeding gains have been made in the past, knowledge gaps exist in respect to flowering, genetics, cytogenetics and options for hybridization that could accelerate crop improvement.

Organic Tuber Production is Promising — Implications of a Decade of Research in India

Alternative soil management practices like organic farming assume significance in the context of climate change for safe food production. Yams white yam, greater yam and lesser yam and edible aroids elephant foot yam EFY , taro and tannia are tuberous vegetables with good taste and nutritive value. Six field experiments were conducted at the ICAR-Central Tuber Crops Research Institute, Thiruvananthapuram, India, over a decade — to compare the varietal response, yield, quality and soil properties under organic vs conventional system and develop a learning system.

Волоча Сьюзан за собой, он использовал ее как живой щит. Преодолев треть ступенек, он почувствовал какое-то движение у подножия лестницы. Стратмор что-то задумал. - И не пытайтесь, коммандер, - прошипел .

 А-а… Зигмунд Шмидт, - с трудом нашелся Беккер. - Кто вам дал наш номер. - La Guia Telefonica - желтые страницы. - Да, сэр, мы внесены туда как агентство сопровождения.  - Да-да, я и ищу спутницу.

 И долго ты собираешься здесь сидеть. - Всю ночь, - безучастно ответила Сьюзан. - Хм-м… - пробурчал Хейл с набитым ртом.  - Милая ночка вдвоем в Детском манеже.

На экране высветилось: СЛЕДОПЫТ ОТПРАВЛЕН Теперь надо ждать. Сьюзан вздохнула. Она чувствовала себя виноватой из-за того, что так резко говорила с коммандером.
