Abstract
A methodology has been developed for identrfyrng relevant quality characteristics that determrne consumer preferences for sorghum The estrmatron results show that a complex mix of evident as well as cryptrc quality characters arelorntly affecting consumer preferences, as reflected in daily market prices Two data sets (a) from one market over 4 years and (b) from four markets in I year were analyzed The estimated coefficients of relevant qualrties can be usedas weights forpredictrng an rndex of consumer preferences for sorghum (SPI) for which the relevant qual~tyc haracters are known It is shown how 25 new sorghum samples are being ranked by SPI based on the two data sets The rankings from both data sets are huhly correlated, mdrcating that for predictive purposes the SPI performs consrstently, regardless of whether it is derlved from time series data or from cross-sectional data The SPI is applicable for large-scde screening. although a few minor issues need to be resolved for increasing confidence and efficiency in rts applrcation
