Abstract

Com o objetivo de selecionar cultivares de tomate industrial mais produtivas e com melhor qualidade, instalou-se dois ensaios em latossolo no Campo Experimental de Bebedouro em Petrolina-PE, no período de maio a outubro de 1996 e 1997. O delineamento experimental foi de blocos ao acaso com quatro repetições e dezoito cultivares (IPA-5, XPH-5720, XPH-12066, XPH-12045, XPH-12068, XPH-12044, Spectrum-151, Spectrum-153, Spectrum-385, Nema-512, Nema-1435, Hypeel-153, Hypeel-108, PSP-58494, PSP-22210, Latino, Zenith e Condor). A produtividade comercial variou de 70,85 a 96,68 t/ha, destacando-se as cultivares IPA-5, XPH-5720, Spectrum-151, Nema-512, XPH-12044, Spectrum-385, Hypeel-153 e XPH-12066, com rendimentos acima de 86,0 t/ha, sendo o menor desempenho apresentado pela cultivar Spectrum-579 com 70,85 t/ha. Quando se ajustou a produtividade em função do ºBrix, verificou-se resultados similares aos anteriores, incluindo-se as cultivares Zenith e XPH-12045, entre as cultivares mais produtivas. O peso médio de frutos oscilou entre 78,75 e 110,96 g, com especial destaque para as cultivares Nema-1435 (110,96 g/fruto) e Hypeel-108 (101,54 g/fruto). Para o ºBrix, observou-se uma oscilação de 4,3º a 6,0º, onde todas as cultivares híbridas superaram a cultivar de polinização aberta IPA-5, que apresentou o mais baixo ºBrix (4,3), tendo os híbridos 'PSP-22210' (6,0º) e 'Zenith' (5,8º) se destacado dos demais. Os resultados obtidos em termos de produtividade e qualidade de frutos permitem indicar como orientação geral para uso dos produtores as cultivares XPH-5720, Spectrum-151, Nema-512, XPH-12044, Spectrum-385, Hypeel-153, XPH-12066, XPH-12045 e Zenith, além da cultivar tradicionalmente plantada (IPA-5).Two field trials were carried out to evaluate processing tomato cultivars in the Experimental Field of Bebedouro, Petrolina, Brazil, in the periods of May to October 1996 and 1997. The experimental design consisted of randomized blocks with 18 cultivars (IPA-5, XPH-5720, XPH-12066, XPH-12045, XPH-12068, XPH-12044, Spectrum-151, Spectrum-153, Spectrum-385, Nema-512, Nema-1435, Hypeel-153, Hypeel-108, PSP-58494, PSP-22210, Latino, Zenith and Condor), with four replications. The commercial yield ranged from 70.85 to 96.68 t/ha. The cultivars IPA-5, XPH-5720, Spectrum-151, Nema-512, XPH-12044, Spectrum-385, Hypeel-153 and XPH-12066 showed the highest commercial yields above 86.0 t/ha, the lowest yield being shown by the cultivar Spectrum-579, with 70,85 t/ha. When the yield was adjusted in function of ºBrix, similar results were observed, 'Zenith' and 'XPH-12045' being included among the highest yielding cultivars. The cultivars Nema-1435 (110.96g/fruit) and Hypeel-108 (101.54 g /fruit) showed the highest average weight of fruits. The soluble solids (Brix) contents ranged from 4.3% to 6.0%, and all hybrids showed higher contents than the open-pollinated variety IPA-5, which showed the lowest brix (4.3(0)), the highest contents being from 'PSP-22210' (6.0(0)) and 'Zenith' (5.8(0)). The results regarding fruit yield and quality allow us to recommend the cultivars XPH-5720, Spectrum-151, Nema-512, XPH-12044, Spectrum-385, Hypeel-153, XPH-12066, XPH-12045 and Zenith for the farmers, besides the traditional cultivar IPA-5.
