6.1.4. Influence of cultural techniques<br />

6.1.4.1. Variety<br />

The main tomato varieties cultivated for processing in the E.C. are : Perfect Peel (PS<br />

1296), Hypeel 244, Titano M, Rio Grande, Heinz 7151, Heinz 3044, Isola, Guadalete (PS<br />

121), Snob (EXH 98063), Soprano, Rio Fuego, Avalon, Cannery Row.<br />

Abushita et al.(1997) analysed tomato fruit from various poorly known cultivars<br />

cultivated in Hungary and found variations on more than 1 to 3-fold: β-carotene varied from<br />

1.15 to 3.7 mg/kg fresh matter and total carotenoids from 18.5 to 60.7 mg/kg fresh matter.<br />

Data from P. Spigno (Cirio Ricerche, Acerra, Naples; personal communication of<br />

unpublished data 1998, 1999) give fruit lycopene content for 24 varieties analysed from not<br />

replicated samples in 1998 and for 29 varieties (not all the same as the previous year)<br />

cultivated in the same conditions in 1999. The mean value was 86.0 mg/kg fresh matter in<br />

1998 and 87.0 mg/kg fresh matter in 1999. The maximum range of values was 34 to 150<br />

mg/kg fresh matter in 1998 and 45 to 163 mg/kg fresh matter in 1999, i.e. about 1- to 4-fold.<br />

Table 9 gives data extracted from the Degree Thesis ‘Carotenoid content in tomato<br />

and its processing products’ (Zanetti, 1996/97).<br />
