“…Similar effects on fruit color were found by Faria et al (2003) and Cá et al (2006). In fact, the three smallest chromaticity angles (nearest to red) among the studied genotypes were TEX-435 of the genotype og c+ /og c rin + /rin, and TEX-437 and TEX-440 of the genotype og c /og c rin + /rin nor + /nor A .…”

“…Araújo et al (2002) have shown that the alcobaça allele in homozygosity (nor A /nor A ) prolongs the postharvest shelf life by the reduction of weight loss and the increase of firmness, and reduces the lycopene and beta-carotene concentrations, besides increasing the Brix/acidity ratio, mainly in association with the genotypes hp/hp and hp + /hp or with og c /og c ; however, its external color limits its commercial use. Cá et al (2006) in the evaluation of the viability of simultaneous use of mutant genes, for maturity and for color in tomato hybrids, in the loci nor A , rin, og c , or hp, found that these genotypes exhibited better post-harvest shelf life than the normal genotypes, and concluded that the genotypic constitutions nor + /nor A og c+ /og c , together with nor + /nor A og c+ /og c hp + /hp, were considered most promising, both for improving postharvest conservation and for maintaining or improving the internal color of tomato fruit. Faria et al (2006) showed that the use of the mutants og c or hp, in heterozygosity, improves the color and increases the concentrations of beta-carotene and lycopene of fruit in rin + /rin and rin + /rin nor + /nor A long shelf life hybrids.…”

-The objective of this work was to evaluate the effects of the mutant alleles alcobaça (nor A ), ripening inhibitor (rin), and old gold crimson (og c ), in heterozygosity or homozygosity, on the expression of color and on the postharvest quality of fruit of experimental tomato hybrids. Fourteen hybrids with contrasting genotypic constitutions in the nor A , rin, and og c loci were evaluated in a randomized complete block design with four replicates. The following fruit postharvest quality traits were evaluated: firmness in the breaker stage, color, and soluble solids content. The rin + /rin and nor + /nor A genotypes increased firmness of tomato fruit at harvest (breaker stage). The rin + /rin genotypes displayed the worst internal fruit color. There was a positive effect of og c+ /og c in improving the internal color of rin + /rin and nor + /nor A fruit, making the color similar to that of the normal genotypes. The combination of the og c /og c rin + /rin nor + /nor A genes is effective to improve tomato fruit firmness, besides maintaining or improving internal color.

“…Mutant alleles that may act markedly on the postharvest shelf life of fruits are "alcobaça" (nor A ), "ripening inhibitor" (rin) and "non ripening" (nor) (Andrade Junior et al, 2005;Kim et al, 2013;Garg et al, 2014). The color mutant alleles "high pigment" (hp) and "old gold crimson" (og c ) are responsible for increasing the production of carotenoids, especially lycopene, in the fruit, improving the nutritional quality, and can be used together with ripening mutant alleles within the same genotype, allowing simultaneous improvements on both postharvest shelf life and nutritional quality of fruit (Andrade Junior et al, 2005;Cá et al, 2006).…”

Given the growing importance of the saladette fresh tomato market in Brazil, the objective of this paper was to assess the combining abilities of lines potentially useful as parents of hybridsin this class. The experiment consisted of28 genotypes, 18 hybrids from a partial diallel crossobtained from crossing two groups of tomato lines (Group I, with 9 parents, and Group II, with 2 parents), 8 F1 experimental hybrids, and 2 commercial checks. Traits evaluated were total yield, mean fruit mass, fruit shelf life, shape and percentsoluble solids. Additive genetic effects were generally more important than non-additive effects for all traits evaluated. The TOM-542 and TOM-734 lines, from group I, and the TOM-720 line, from group II, presented high general combining ability (GCA) estimates for most of the traits of importance for saladette tomatoes, and were therefore considered suitable parents of hybrids of this class. Higher fruit shelf life of TOM-723 as a parental line compared with TOM-720 (Group II), was mainly attributed to the presence in the former of the nor A allele, which controls longer fruit shelf life. F1 hybrids (TOM-542 x TOM-720), (TOM-580 x TOM-720), (TOM-734 x TOM-720), and (TOM-727 x TOM-720) showed good performance and fruit quality and thus constitute possible commercial varieties.Key words: Solanum lycopersicum, saladette tomatoes, partial diallel. Capacidade combinatória de linhagens de tomateiro em híbridos do tipo italiano ResumoDevido à crescente importância do mercado do tomate tipo italiano no Brasil, objetivou-se conhecer a capacidade combinatória de linhagens de tomateiro potencialmente utilizáveis como genitoras de híbridos voltados a esse segmento. O experimento constituiu-se de 28 genótipos, sendo 18 híbridos oriundos de um dialelo parcial, obtido pelo cruzamento entre dois grupos de linhagens: Grupo I (nove genitores) e Grupo II (dois genitores), oito híbridos adicionais e duas testemunhas comerciais. Foram avaliados produção total, massa média de frutos, firmeza, formato e teor de sólidos solúveis. Houve predominância dos efeitos gênicos aditivos para todas as características avaliadas. As linhagens TOM-542 e TOM-734, pertencentes ao Grupo I, e TOM-720, Grupo II, apresentaram estimativas elevadas de capacidade geral de combinação para a maioria das características de importância para o segmento de tomate italiano, portanto, recomendadas para a obtenção de híbridos desse tipo. A superioridade da linhagem TOM-723 sobre a TOM-720 (Grupo II) quanto à firmeza de frutos foi atribuída, principalmente, à presença, na primeira, do alelo nor A , que condiciona maior conservação pós-colheita. Os híbridos experimentais F1 (TOM-542 x TOM-720), F1 (TOM-580 x TOM-720), F1 (TOM-734 x TOM-720) e F1 (TOM-727 x TOM-720) apresentaram bom desempenho agronômico e qualidade de fruto, constituindo possíveis materiais comerciais.Palavras-chave: Solanum lycopersicum, tomate saladette, dialelo parcial.

“…Regarding the use of ripening mutants, the allele rin (ripening inhibitor) is the most used allele in modern cultivars (Cá et al, 2006). These alleles delay ripening and prolong shelf life, interfering mainly on the firmness and carotenoid pigments synthesis, in addition to being useful for a better understanding of the processes which regulate the maturation and the development of new cultivars with longer shelf life (Dias et al, 2003;Faria et al, 2006;Cá et al, 2006).…”

The high temperature of growth environment can affect the postharvest quality of tomato fruits. In this situation, an alternative for the farmers is the use of hybrid cultivars that produce long shelf life fruit with longer postharvest shelf life when compared to normal varieties of fruits. The objective of this research was to compare the postharvest conservation of fruits of structural long shelf life tomato hybrids and with the mutant rin. The fruits evaluated were from fifteen tomato genotypes produced under the edaphoclimatic conditions of the southern State of Tocantins, being four of them long shelf life type hybrids (with rin allele) which were: Tyler, Rebeca, Carmem and AF 13527; nine of them structural long shelf life hybrids: Lumi, Débora Max, Michelli, Tammy, AF 12525, AF 11097, AF 13363, AF 13364 and AF 13525; and two normal fruit cultivars: Santa Clara and Drica. The fruits were harvested at the breaker stage and stored in a controlled environment (20 °C and relative humidity of 60%). The half-life firmness of fruits of genotypes with a structural genotypic long shelf life background ranged from 6.25 to 13.44 days for the genotypes Tammy and AF13525, respectively, not differing from the long shelf life genotypes with rin allele. Despite the fact that daytime temperatures are higher than those recommended for the tomatoes crops, it was observed that if the fruits are stored in appropriate conditions (20 °C and relative humidity of 60%), the color and firmness of the fruits with a long shelf life genotypes with rin allele and structural genotypic background evolve more slowly than the fruits of normal genotypes. Under these conditions, it took the fruits 7 to 8 days to acquire a red color on more than 80% of the surface after being harvested.Index terms: Solanum lycopersicon; hybrids; firmness; color. RESUMOA temperatura elevada do local de cultivo pode afetar a qualidade pós-colheita dos frutos do tomateiro. Nessa situação, uma alternativa para os produtores, é o uso de cultivares híbridas que produzem frutos longa vida com maior tempo de conservação em pós-colheita, quando comparado com cultivares de frutos normais. Neste trabalho, objetivou-se avaliar a conservação em pós-colheita de frutos de híbridos de tomateiro longa vida estrutural e com mutante rin cultivados em duas épocas sobre ambiente protegido na região Sul do estado do Tocantins. Os tratamentos foram constituídos de 15 genótipos, sendo quatro híbridos com frutos tipo longa vida (com alelo rin) que foram: Tyler, Rebeca, Carmem e AF 13527; nove híbridos com frutos tipo longa vida estrutural: Lumi, Débora Max, Michelli, Tammy, AF 12525, AF 11097, AF 13363, AF 13364 e AF 13525 e duas cultivares de frutos normais: Santa Clara e Drica. Os frutos foram colhidos no estádio de breaker e armazenados em ambiente controlado (20 ºC e umidade relativa de 60%). A meia vida da firmeza dos frutos dos genótipos com background genotípico longa-vida estrutural variou de 6,25 a 13,44 dias nos genótipos Tammy e AF13525, respectivamente, não diferind...
