Abstract
Tomato (Lycopersicon esculentum Mill.) is the second most important vegetable with one of the biggest producing areas worldwide, and an increasing tendency in Hungary as well. To fulfil the growing demands of the industry the producers must use the most suitable genotypes for the given conditions. In the experiment six genotypes (‘Heinz 1015 F1‘,‘Heinz 9478 F1‘,‘Kecskeméti 407‘,‘NUN254 F1‘,‘Prestomech F1‘ and ‘Rustico F1‘) were evaluated for different quality parameters: fruit shape index (length/diameter), firmness (g cm-2), force needed to tear the skin (kg-1) and consistency of tomato puree (g*sec). According to the results, the ‘Heinz 1015 F1‘ and ‘Heinz 9478 F1‘ were the most suitable genotypes for industrial processing in the mean of fruit quality. Strong positive correlation between consistency of juice and fruit shape index (r=0.891) and firmness of berry (r=0.882) was confirmed. The results have proved the necessity of these quality parameter measurements, which are important for the evaluation of raw material.
Highlights
In Hungary, the industrial tomato is harvested by machine from the beginning of August until the end of September
Among the economic and quality parameters, the yield plays an important role which can determine the profitability of the genotypes
The results show that the leading industrial tomato hybrids, ‘Heinz 1015 F1‘ and ‘Heinz 9478 F1‘ produced the highest yield (> 2500 g/plant) which were significant differences
Summary
In Hungary, the industrial tomato is harvested by machine from the beginning of August until the end of September. Several studies have proved the clear connection between physical properties of variety and suitability for mechanical harvest (Desmet et al, 2002; Devaux et al, 2005; Linden et al, 2006; Zeebroeck et al, 2007; Li et al, 2010a).These parameters include size and weight of berry, shape, colour and density of fruit. These parameters are important for the proper equipment of harvest (Kilickan & Guner, 2008)
