Subject Sorghum
 
Description 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
