Do yams (Dioscorea spp.) host endogenous viral sequences ? [PDF]

, 2011
Yams (Dioscoreae sp) are important food commodities in tropical and subtropical areas of Africa, the Caribbean, South America and the Pacific where they play a key role in food security. Yams are vegetatively propagated crops.

Mini tuber production using yam (Dioscorea rotundata) vines

Tropical Science, 2005
AbstractMini tubers were produced from two varieties of Dioscorea rotundata using vine cuttings planted in carbonized rice husk or coco‐peat in a screen house. The cuttings established better and produced more mini tubers in carbonized rice husk than in coco‐peat 100 days after planting.

Characterizing quality traits of boiled yam: texture and taste for enhanced breeding efficiency and impact

Journal of the Science of Food and Agriculture, Volume 104, Issue 8, Page 4626-4634, June 2024.
Abstract BACKGROUND Boiled yam key quality attributes typical for West African consumers are that it is crumbly, easy to break and has a sweet taste. New yam varieties are being developed but high‐ or medium‐throughput tools to assess the required quality traits and their range of acceptance are limited. This study assessed the acceptance thresholds of

Instrumental procedures to assess the extensibility of pounded yam and relationship with sensory stretchability and consumer preferences

Journal of the Science of Food and Agriculture, Volume 104, Issue 8, Page 4738-4745, June 2024.
Abstract Background Stretchability is the most important sensory textural attribute considered by consumers of pounded yam. It is important both for the processor during pounding and for the consumer during consumption to measure this attribute while screening large populations of yam genotypes intended for advanced breeding and eventual adoption ...

Rapid detection of potyviruses from crude plant extracts [PDF]

, 2018
Potyviruses (genus Potyvirus; family Potyviridae) are widely distributed and represent one of the most economically important genera of plant viruses. Therefore, their accurate detection is a key factor in developing efficient control strategies. However,

In situ dynamic rheological analysis of raw yam tubers: a potential phenotyping tool for quality evaluation

Journal of the Science of Food and Agriculture, Volume 104, Issue 8, Page 4746-4757, June 2024.
Abstract Background Most rheological analyses in yam have been done on starch gels, which requires starch extraction from the tubers. In situ rheology bypasses the need of starch extraction and relies on the original cell structure and complex matrix organization under stress or strain.

Identification of candidate flowering and sex genes in white Guinea yam (D. rotundata Poir.) by SuperSAGE transcriptome profiling.

PLoS ONE, 2019
Dioecy (distinct male and female individuals) and scarce to non-flowering are common features of cultivated yam (Dioscorea spp.). However, the molecular mechanisms underlying flowering and sex determination in Dioscorea are largely unknown.

Quantitative trait loci and candidate genes for physico‐chemical traits related to tuber quality in greater yam (Dioscorea alata L.)

Journal of the Science of Food and Agriculture, Volume 104, Issue 8, Page 4872-4879, June 2024.
Abstract BACKGROUND Starch, dry matter content (DMC), proteins, and sugars are among the major influences on yam tuber quality. Genetic improvement programs need simple, rapid, and low‐cost tools to screen large populations. The objectives of this work were, using a quantitative trait loci mapping approach (QTL) on two diploid full‐sib segregating ...

Relative efficiency of positive selection and tissue culture for generating pathogen-free planting materials of yam (Dioscorea spp.) [PDF]

, 2017
Open Access JournalYams are staples in West Africa. They are propagated from tubers in an informal seed system. This encourages a build-up of diseases, and necessitates the rapid development of a formal seed system where certified seeds are functional ...
