SANTOS, Fabrício Franco B dos; RIBEIRO, Ailton; SIQUEIRA, Walter José and MELO, Arlete MT de. Agronomic attributes of F1 fresh market tomato hybrids. Hortic. Bras. [online]. 2011, vol.29, n.3, pp.304-310. ISSN 0102-0536. http://dx.doi.org/10.1590/S0102-05362011000300008.
The study aims to obtain and select F1 resistant hybrids of tomato for fresh market and evaluate their agronomic attributes in field conditions. The work was carried out at Nunhems Experimental Station, located in Paulínia, São Paulo State, Brazil, from February to June 2008. The experimental design was completely randomized blocks with 36 treatments, four replications and ten plants per plot. Based on the grouping of means by Scott-Knott test, the performance of hybrids for seven agronomic traits showed great variability among genotypes for fruit length and width with four groups of means. There was good variability for yield per plant, and plant height with three groups of means for each character. The traits fruit number per plant, cluster number per plant, and distance between the first cluster and the ground showed little divergence with two grouping means. HE-38 and HE-14 outperformed the standard Aplauso for fruit yield per plant showing positive heterotic effects.
