“…Fruit firmness is usually directly propositional to fruit shelf life, and these mutants have low pectolytic activity (Kopeliovitch et al, 1979). Rodriguez et al (2010) have recorded similar findings in the F 1 cross ca x nor, and Dias et al (2003) have found that the F 1 ('TOM591' x 'Mospomorist') alc + /alc genotype improves the rate of fruit firmness to 8.6128 N/m 2 compared with that in the parents and contributes to an increase in post-harvest shelf life.…”

ABSTRACT.Breeding for better quality fruits is a major focus for tomatoes, which are continuously subjected to post-harvest losses. Several methods have been used to improve the fruit shelf life of tomatoes, including the use of ripening gene mutants of Solanum lycopersicum. We developed extended shelf-life tomato hybrids with better quality fruits using ripening mutants. Nine tomato crosses were developed using 3 fruit ripening gene mutants of S. lycopersicum [alcobaca (alc), non-ripening, and ripening inhibitor] and 3 agronomically superior Indian cultivars ('Sankranti', 'Vaibhav', and 'Pusaruby') with short shelf life. The hybrid progenies developed from alc x 'Vaibhav' had the highest extended shelf life (up to 40 days) compared with that of other varieties and hybrids. Further, the F 2 progenies of alc x 'Vaibhav' were evaluated for fruit quality traits and yield parameters. A wide range of genetic variability was observed in shelf life (5-106 days) and fruit firmness (0.55-10.65 lbs/cm 2 ). The potential polymorphic simple sequence repeat markers underlying shelf life traits were identified in an F 2 mapping population. The marker association with fruit quality traits and yield was confirmed with single-marker analysis and composite ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 12 (1): 506-518 (2013) Development of an extended shelf-life tomato 507 interval mapping. The genetic parameters analyzed in the parents and F 1 and F 2 populations indicated that the cross between the cultivar 'Vaibhav' and ripening gene mutant alc yielded fruit with long shelf life and good quality.

“…We also do not know if LA0716 flowers are sensitive to ethylene, because flower responses were not evaluated in this accession. S. lycopersicum 'OH981067' and 'Seleccion Mallorquin' have mutations in the Nac Nor gene, which confers low ethylene sensitivity and extended shelf life in fruit (Dias et al, 2003;Kopeliovitch et al, 1980). In other studies, fruit from these plants were shown to be less ethylene-sensitive, but leaf evaluations were not reported.…”

The family Solanaceae, which includes both important crop and ornamental species, is generally considered to have high sensitivity to ethylene. Our objectives were to evaluate ethylene sensitivity between accessions with the family Solanaceae and to determine whether similar sensitivity was observed in seedlings and mature plants. For the seedling evaluations, seeds were germinated and grown in the dark on filter paper saturated with 0 or 100 μM 1-aminocyclopropane-1-carboxylic acid (ACC; the immediate precursor to ethylene). The relative hypocotyl length at 100 μM ACC was compared with untreated control (0 μM) seedlings. Mature plants were treated with 0 or 10 μL·L−1 ethylene in the dark for 24 hours. Ethylene responses including flower abscission, flower senescence, and epinasty were observed and quantified. Seedlings and mature plants were classified as having no response, low, medium, or high ethylene sensitivity based on the severity of the ethylene responses observed. Sensitivity differences were observed among seedling, juvenile, and mature plants, and a range of ethylene responses and symptom severity was observed between accessions within a species. The majority of the accessions were classified as medium or high ethylene sensitivity at both the seedling and mature plant stages. Solanum melongena ‘Black Beauty’ (eggplant) had a low response to ethylene at the seedling stage and a high response at the mature plant stage, whereas Petunia ×hybrida ‘Daddy Orchid’ had a high response at the seedling stage and a low response at the mature plant stage. Peppers (Capsicum annum), tomatoes (Solanum lycopersicum), and tomatillos (Physalis ixocarpa) exhibited both floral and vegetative symptoms of ethylene damage, whereas calibrachoas (Calibrachoa ×hybrida), eggplants, nicotianas, and petunias exhibited only floral symptoms. The most common floral response to ethylene treatment was flower abscission, which was observed in almost all of the Solanum, Capsicum, and Nicotiana accessions. We consistently observed ethylene-induced epinasty in the genus Capsicum and in all of the Solanum except eggplant. Our results indicated that developmental stage influenced ethylene sensitivity, and there was not a consistent correlation between seedling and mature plant responses within the Solanaceae accessions that we evaluated.

“…The LSL phenotype has been related to the alc mutation (e.g., Kopeliovitch et al, 1981;Lobo et al, 1984;Mutschler, 1984a;Casals et al, 2012;Conesa et al, 2014), described in the 'Alcobaça' landrace (Almeida, 1961;Leal and Tabim, 1974). First reports for shelf-life in 'Alcobaça' were up to 316 days (Leal and Tabim, 1974), although further reports are considerably shorter (up to 33 days; Kopeliovitch et al, 1980;Mutschler 1984b;Mutschler et al, 1988;Mutschler et al, 1992;Dias et al, 2003). The alc mutation is present in 'de Penjar' from Catalonia and Valencia and 'de Ramellet' from the Balearic Islands (Casals et al, 2012;Bota et al, 2014).…”

Mediterranean Long Shelf-Life Landraces: An Untapped Genetic Resource for Tomato Improvement

et al. 2020

View full text Add to dashboard Cite

The Mediterranean long shelf-life (LSL) tomatoes are a group of landraces with a fruit remaining sound up to 6-12 months after harvest. Most have been selected under semiarid Mediterranean summer conditions with poor irrigation or rain-fed and thus, are drought tolerant. Besides the convergence in the latter traits, local selection criteria have been very variable, leading to a wide variation in fruit morphology and quality traits. The different soil characteristics and agricultural management techniques across the Mediterranean denote also a wide range of plant adaptive traits to different conditions. Despite the notorious traits for fruit quality and environment adaptation, the LSL landraces have been poorly exploited in tomato breeding programs, which rely basically on wild tomato species. In this review, we describe most of the information currently available for Mediterranean LSL landraces in order to highlight the importance of this genetic resource. We focus on the origin and diversity, the main selective traits, and the determinants of the extended fruit shelf-life and the drought tolerance. Altogether, the Mediterranean LSL landraces are a very valuable heritage to be revalued, since constitutes an alternative source to improve fruit quality and shelf-life in tomato, and to breed for more resilient cultivars under the predicted climate change conditions.
