Inheritance of taste components in tomato

Components of tomato taste can be modeled from a set of instrumentally meas ured parameters. The inheritance was studied of two texture parameters with an effect of mealiness and pleasantness of taste: BFp and EBp. A recombina nt inbred line population (F6) of the cross tomato cv Moneymaker x L. pimpi nellifolium was analyzed for these parameters, and a molecular linkage map was developed for this population. A single QTL region on chromosome 9 was found with an effect on both BFp and EBp. The QTL explained 18.2 and 18.8 % of the population variances, and 19.5 and 39.0 % of the parental differenc es respectively for BFp and EBp.
