Conteúdo: 	The study performed on the relationship between yield and eleven metric traits in four tomato varieties and their crosses (Cavicchi and Silvetti, 1976 a) have suggested that heterosis for yield might depend on the sum of contributions from many characters. According to Williams and Gilbert (1960) heterosis for yield is due to specific genetic factors affecting the character and obtained only when yield components (number and wight of berries, flowering time) do not show heterosis. On the contrary, somatic and physiological interactions apper to be the most important factors. On the basic of the results reported in our quoted work (Cavicchi and Silvetti, 1976 a) it appeared to us interesting to provide further evidence for better understanding of these hypothe-sis on the basis of a multivariate definition of yield.
