“…As previous literature shows, consumers are willing to pay more for foods they perceive as more sustainable and/or of higher quality [29]. This is not only the case for national, regional, or local foods, particularly tasty foods, and organic foods [30][31][32], but also traditional or old vegetable or fruit varieties or animal breeds, as they are typically associated with a particular locality, region or country, cultural heritage and exceptional sensory characteristics [27,[33][34][35][36][37][38][39]. In fact, a recent study by Tyack and Ščasný [40] shows, that consumers are even willing to pay for ex-situ conservation of genetic resources.…”

To increase the diversity in the food system from seed to fork, participatory on-farm breeding schemes have been proposed. For participatory on-farm breeding schemes to be successful, consumers need to be willing to compensate farmers for their efforts in breeding and in diversifying their cultivation. Using vegetables as an example, we investigated whether consumers of four selected European countries liked the idea of having farmers breed their own varieties and whether they would be willing to pay a premium for farmers' as compared to standard varieties in a supermarket setting. The data was collected in an online survey and a willingness to pay was elicited using a contingent valuation approach. After providing respondents with information about the problem (diversity loss), solution (on-farm breeding), and the benefits of farmers' varieties, consumers' acceptance was very high and consumers were willing to pay a small premium. Our findings suggest that farmers' varieties can be appealing to a wide range of consumers if the appropriate information is provided, as they not only address the increasing demand for more sustainable products but also for more food diversity and tasty products. To our knowledge, this is the first study to examine consumer preferences for farmers' varieties for food system diversity.

“…Moreover, small producers of tomato require varieties or new materials not necessarily with high productivity but with high consumption value associated with flavor, aroma and texture of fruit. Until now, farmers developed or selected new varieties or local varieties from the old varieties, new genetic crossings among commercial varieties and local genotypes or by induced crossing among landraces in which the advanced genotype is highly variable in plant and fruit traits (Mazzucato et al, 2010;Cebolla-Cornejo et al, 2013;Rocchi et al, 2016). Therefore, the results suggest that it is feasible to select landraces (I-07, I-18 and I-31) or generate non-conventional F 1 hybrids (H-06, H-06a, H-19, H-64, H-67, H-68 and H-69) with high productivity and healthy plants with similar performance to that of advanced lines such as (LA-108 and LA-113a).…”

“…In different countries, old varieties or heirlooms of tomato are being selected and conserved by farmers, and although these farmer varieties have phenotypic heterogeneity, the fruit quality is highly preferred by consumers. Some examples of such farmer varieties are ' Valenciano', 'Muchamiel' and 'De Penjar' in Spain (Cebolla-Cornejo et al, 2013); 'Pomodoro di Mercatello' (Rocchi et al, 2016), 'A pera Abruzzese' (Mazzucato et al, 2010), 'Pomodoro di Sorrento', 'Belmonte', and 'Canestrino di Lucca' in Italy (Parisi et al, 2016); a dozen heirlooms in Brazil (Vargas et al, 2015); 'Tomataki Santorinis' from Santorini Island of Greece (Koutsika-Sotiriou et al, 2016); and different local varieties from Eritrea in Africa (Asgedom et al, 2011). In México, tomato landraces are commonly found from north to south, in addition to ruderal forms of S. lycopersicum var.…”

“…Farmers know that the varieties, agroecological conditions and crop management determine the flavor, taste and nutritional quality of the tomato fruit (Cebolla-Cornejo et al, 2011). Moreover, the product destination is local or organic markets in which the quality of fruit is more important than the yield per area (Rocchi et al, 2016). Koutsika-Sotiriou et al (2016) compared breeding between farmers and formal plant breeding using tomato heirlooms and concluded that farmers generated populations with low productivity, high fruit homogeneity and broad adaptability, whereas the breeders produced advanced lines or selected populations with high productivity, high selection efficiency and specific adaptations.…”

Tomato is broadly distributed in tropical and subtropical America, where small farmers cultivate commercial and landraces or heirloom genotypes, which exchange genes within them when are planted in the same plot. In this context, three different genetic groups of tomato were evaluated for agromorphological and yield traits under greenhouse to assess the differences in function of the genotypic homogeneity and heterogeneity. Twenty-four non-conventional hybrids (F 1 , population-xadvanced lines), seventeen landraces and six advanced lines (F 8) were evaluated in a randomized complete block design with three repetitions. Significant differences (p ≤ 0.05) were determined among genetic groups for all variables evaluated, except in days to ripening of fruits at the fifth branch, and within genetic groups, significant differences were also detected. Six hybrids, three landraces and two advanced lines presented remarkable agronomic responses in yield per plant. The hybrids and landraces had high phenotypic variability in plant and fruit traits, with flat-rounded or lightly flattened fruit shapes, qualities demanded in the local markets, and a yield of 2 kg per plant. In Oaxaca, Mexico, small-scale farmers readily accept these heterogeneous genetic groups of tomato. High homogeneity characterized the advanced lines, with a fruit shape convenient for national and international markets.

“…All these findings revealed that environmental conditions distributes the better tomato production. Agro-diversity was also influenced on morphological characteristics of tomato fruit [27]. So, climatic conditions and soil contents were influenced on the growth and nutritional values of tomato varieties.…”

This research work was conducted at District Layyah to evaluate the impact of ecoclimatic conditions, soils texture on growth parameters and nutritional values of three tomato varieties. The tested varieties were DT97/162A(R), DT97/215.A, local V1 and local V2. They were assigned randomly into different blocks in the fields as completely randomized block design (RBCD). In present results, physio-chemical properties of soil, nutritional values and morphometric characteristics of three tomato varieties were analyzed and documented. The pH 7.6 was measured. Available Phosphorus was calculated as 7.8 mg/kg. Total Nitrogen appeared in collected samples was 0.6%. Ca 2+ indicated maximum exchangeable cation (2.9 mg/g) as comparison to other cations. In exchangeable acidity, Fe (ppm) indicated highest value (19.4 meg/100g). Maximum (42.55%) protein percentage produced by local variety V2 while highest (41.50%) fat shown by variety DT97/162A(R). Fiber percentage appeared almost similar in all analyzed varieties. Vitamin C (0.37 mg/100g) was measured highest in local variety V2. The highest values of Ca (0.395%), Mg (0.215%), K (0.182%) and P (0.572%) were also observed in tomato local variety V2. However, tomato variety local V2 showed higher plant height. Tomato variety DT97/162A(R) showed highest number of leaves while DT97/215A indicated minimum values. Number of flowers and number of fruits were produced almost similar in all varieties. Hence, local variety V2 showed highest growth, better yield performance and high nutritional values. Therefore, it is concluded that a local variety (V2) suggested as the suitable tomato variety for the environmental conditions of District Layyah, Pakistan.
