Effects of the alleles alc, ogc and hp on ripening and postharvest shelf-life characteristics of tomato fruits.

 

The experiment was carried out in the plastic greenhouse in Ijaci, Minas Gerais, Brazil, to evaluate tomato hybrids with the following genotypic constitutions with regard to alleles of alc (alcobaca or long shelf life), ogc (old gold crimson) and hp (high pigment): alc+/alc+ ogc+/ogc+ hp+/hp+; alc+/alc ogc+/ogc+ hp+/hp+; alc+/alc ogc+/ogc hp+/hp+ and alc+/alc ogc+/ogc hp+/hp, together with female parental lines (alc+/alc+ ogc+/ogc+ hp+/hp+) and the control cultivar Flora-Dade (alc+/alc+ ogc+/ogc+ hp+/hp+). The experiment was established in a randomized complete block design with 28 treatments, 3 replications and 10 plants per plot. The genotype alcc+/alc promoted an increase in fruit firmness, a reduction in the size of the peduncular scar and a loss of fruit weight, as well as a slight delay in the uptake of red fruit coloration relative to the normal genotype alc+/alc+. The alleles ogc and hp in the heterozygous state did not contribute to increased firmness of alc+/alc fruit. While the allele

 ogc in the heterozygous state did not promote an increase in red coloration of alc+/alc fruit, the hp allele did.
