Grape samples from nine progeny populations totaling 580 individual se
edlings were evaluated organoleptically for the stenospermic character
by four independent judges. These subjective evaluations were correla
ted to a standard objective procedure for evaluating stenospermy, as w
ell as other variables associated with the sinker content of each samp
le. Correlations were diverse between organoleptic evaluations and cal
culated variables. Organoleptic evaluations more closely agreed with t
he objective stenospermic evaluation for seeded grapes. Highest correl
ations were realized between organoleptic evaluation and relative seed
mass. These results indicate that organoleptic evaluations should not
be used in genetic studies to discern between seeded and stenospermic
accessions.
