Abstract

A group of 28 tomato genotypes including alc⁺/alc hybrids and alc⁺/alc⁺ lines were grown in a greenhouse, in a completely randomized block design with three replications and ten plants per plot, to study the effect of alc, og^c and hp alleles and heterosis on the following tomato production characteristics: number of bunches per plant, number of fruits per bunch, number of commercial fruit per bunch, early production of commercial fruits, total production of fruits, production of commercial fruits, mean weight of fruits and mean weight of commercial fruits. It was concluded that alc, og^c and hp alleles did not influence these characteristics and that the positive heterosis for number of fruits may compensate the absence or lower heterosis for the mean weight of fruits.
