Abstract

In a six parent tomato (Lycopersicon esculentum Mill) diallel cross, specific heterosis was more important for marketable yield (PFC) than for its components - average weight (PMFC) and number of marketable fruit (NFC). Correlation coefficients between F1 hybrid means and parental means were larger for PMFC and NFC than for PFC. The product of PMFC by NFC parental means can be used more efficiently as an estimate of F1 hybrid PFC's than PFC parental means themselves.
