“…However, as a result of domestication and intensive breeding, the cultivated tomato germplasm has a rather narrow genetic base (Bergougnoux 2014), meaning that only a subset of the genes and alleles available in the wild progenitor gene pool are still present among crop cultivars (Godfray et al 2010;Ladizinsky 1985;Olsen and Wendel 2013). Especially, as breeding efforts have mainly targeted yield at more or less optimal cultivation conditions, it seems likely that abiotic stress tolerance traits have been lost (Ladizinsky 1985;Paran and Van Der Knaap 2007).…”

Exploring the natural variation for reproductive thermotolerance in wild tomato species

Climate change has become a serious threat for crop productivity worldwide. The increased frequency of heat waves strongly affects reproductive success and thus yield for many crop species, implying that breeding for thermotolerant cultivars is critical for food security. Insight into the genetic architecture of reproductive heat tolerance contributes to our fundamental understanding of the stress sensitivity of this process and at the same time may have applied value. In the case of tomato (Solanum lycopersicum), germplasm screenings for thermotolerance have often used yield as the main measured trait. However, due to the complex nature of yield and the relatively narrow genetic variation present in the cultivated germplasm screened, there has been limited progress in understanding the genetic basis of reproductive heat tolerance. Extending the screening to wild accessions of related species that cover a range of climatic conditions might be an effective approach to find novel, more tolerant genetic resources. The purpose of this study was to provide insight into the sensitivity of individual reproductive key traits (i.e. the number of pollen per flower, pollen viability and style protrusion) to heat-wave like long-term mild heat (LTMH), and determine the extent to which genetic variation exists for these traits among wild tomato species. We found that these traits were highly variable among the screened accessions. Although no overall thermotolerant species were identified, several S. pimpinellifolium individuals outperformed the best performing cultivar in terms of pollen viability under LTMH. Furthermore, we reveal that there has been local adaptation of reproductive heat tolerance, as accessions from lower elevations and higher annual temperature are more likely to show high pollen viability under LTMH.

“…portaenxertos resistentes. Dentre as culturas comumente enxertadas, destaca-se o tomateiro, uma das hortaliças mais consumidas no mundo e a sétima cultura mais importante na alimentação mundial (Bergougnoux, 2013). Dados da FAO mostram que a produção brasileira no ano de 2011 foi de aproximadamente 4,4 milhões de toneladas, com área colhida de 71.473 ha, fazendo do Brasil o oitavo maior produtor mundial (FAO, 2013); contudo, a produtividade brasileira ainda é relativamente baixa, comparada à de países com alta tecnologia de produção.…”

RESUMO Visando avaliar a compatibilidade de tomateiros enxertados em diferentes portaenxertos, sob ambiente protegido, foi determinada a atividade das enzimas antioxidantes, peroxidases (POXs), polifenoloxidase (PPO) e superóxido dismutase (SOD). A primeira etapa experimental consistiu na avaliação, aos seis e onze dias após a enxertia, das mudas enxertadas e não enxertadas com três combinações de enxertia (Maxifort, Multifort e autoenxertia), em três regiões de coleta no caule: a) 2 cm acima da região da enxertia; b) na região de enxertia e c) 2 cm abaixo da região da enxertia, além do tratamento adicional, constituído de mudas não enxertadas de 'Alambra' (pé franco). O delineamento experimental foi inteiramente casualizado, em esquema fatorial 3x3+1, com cinco repetições. Na segunda etapa experimental houve o transplantio das mudas para a casa de vegetação, com as combinações de enxertia 'Maxifort', 'Multifort', autoenxertia e pé franco, considerando nas parcelas as combinações da enxertia e nas subparcelas os quatro períodos de coleta 30, 60, 90 e 120 dias após o transplantio. O delineamento experimental foi em blocos ao acaso, em esquema de parcela subdividida, sendo cada parcela experimental constituída de seis plantas, com seis repetições. Os resultados da primeira etapa mostram que houve incremento na atividade das POXs e PPO durante o pegamento das enxertias com os portaenxertos 'Maxifort', 'Multifort' e também na autoenxertia. Na segunda etapa, observou-se maior incremento na atividade de SOD e POXs para o portaenxerto 'Multifort' aos 120 dias após o transplantio. As plantas enxertadas e o pé franco não apresentaram indícios de incompatibilidade, sendo o aumento da atividade enzimática atribuído ao processo de cicatrização e lignificação das mudas enxertadas, tendo mantido esse comportamento ao longo do ciclo de crescimento e desenvolvimento das plantas de tomateiro. A produção por planta não sofreu influência da enxertia.

“…Otherwise, the area dedicated to tomato culture is very small in Northern Europe. It is noteworthy that these countries produce most of their tomatoes under controlled greenhouse conditions (Bergougnoux, 2014). Source: FAO, 2015 When Turkey is compared to EU, tomato production quantity of Turkey increased constantly in analyzed period.…”

Tomato is a native tropical America and considered to have originated in the tropical coastal areas of Ecuador, Peru or Bolivia and portions of Northern Chile. Tomato is one of the most consumed vegetables in the world together with potatoes and onions. Although Turkey is the 4th producer of tomato, it remains 6th exporter of this commodity. Processing tomato production is intensive mainly in Marmara and Aegean Regions, especially in Bursa, Manisa and İzmir provinces. Investigations show that real prices which farmers receive from both tomato paste and fresh tomato constantly decline. Turkey is an exporter of tomato and 60.3% export share of total Fresh and frozen tomato is exported to Russia. In tomato yield, production and consumption, Turkey is above the world average. However, export proportion of total production is insignificantly observed. Export to EU countries should be raised to develop the current status of tomato sector in Turkey.
