Sensory profiling was applied as an effective tool in melon characterization to evaluate twenty-six melon varieties, landraces and commercial hybrids over 3 years of harvesting. The landraces were from Villaconejos, a Madrilean village historically specialized in melon cultivation. These landraces have remarkable morphological and molecular diversity according to previous studies. Individual panel results related to color, firmness, juiciness, sweetness, acidity and fibrosity, and seven different aromas of melon fruits were analyzed using a multivariate analysis. The results of these analyses showed that Villaconejos accessions were highly diverse and distinct from the reference accessions. The comparison of specific and homologous traditional and commercial varieties indicated that genetic improvement programs have had a remarkable effect on some sensorial attributes. Most Villaconejos varieties exhibited noteworthy particularities that the consumer panel considered quality marks, such as the sweetness and acidity of 'Mochuelo Tradicional' or the juiciness of 'Melón Azul'. The most preferred group was composed of seven varieties. The first three preferred varieties were Villaconejos landraces, as was the fifth variety in this group. In conclusion, these results indicate that Villaconejos landraces could provide Inodorus genetic resources with priceless sensorial attributes that are appreciated by consumers and are currently unavailable in the melon market. Therefore, these landraces constitute an irreplaceable resource for farmers, breeders and seed companies. © 2012 Springer-Verlag.

The present article deals with the relation between fruit texture and human perception in a large group of non-climacteric melon genotypes, by measuring several mechanical properties and discussing their relationship with some sensory parameters. Juiciness resulted the main factor in melon consumer acceptance, but firmness, cohesiveness, fibrousness, springiness, and resilience also defined quality groups. Consumers (53.9%) preferred a fruit of medium firmness, outstanding juiciness, and medium-high fibrousness; 24.5% of consumers have chosen a less firm fruit than the majority, while 21.6% of consumers wanted a less fibrous melon. The combination of textural traits could be larger applied in future breeding programs. © Copyright 2015 Taylor & Francis Group, LLC.

Seven typologies of melon belonging to Inodorus and Cantalupensis horticultural groups have been assayed in relation to their sensory and physical-chemical characteristics. Sensory analysis has been performed by means of a descriptive profiling based on objective scales and a trained panel. Multivariate analysis was applied to the individual results associated with the attributes of color, firmness, juiciness, sweetness, acidity, fibrosity and seven different aromas. Accuracy of the panel members and validity of the method were confirmed by the correlation between sensory scores and physical-chemical rates of firmness, juiciness, o Brix and pH. Relationships between sensory parameters and consumer preferences were also identified, resulting in concrete quality marks: high sweetness and juiciness, yellow flesh, moderate acidity and aromas of cucumber, watermelon, pineapple and peach. Additionally, the consumer's internal map of preferences was developed in order to guide future genetic improvement programs. © 2010 Springer-Verlag.

At the mountain area close to the city of Madrid, common beans were one of the main food crops present in everyday diet until 1960. This paper describes the morphological diversity, for forty-six phenological and morphological traits, found in forty-three traditional varieties of common beans collected in this area and seven commercial varieties used as reference. That comparison suggests that common bean breeding programs have led to later varieties with a higher production of straight pods. Quantitative traits showed also similar values when compared to the Iberian common bean collection, except for the phenological and seed size characters. The phenological differences could suggest an ecological adaptation of the studied landraces to the regional environmental conditions. The different seed size averages of both collections might correspond to the scarce presence of smaller seed-type common beans in Madrid collection. All the accessions collected in the Sierra Norte of Madrid belong to any of the groups included in the Spanish core collection. Madrilenian collection is also composed by indeterminate growth habit varieties, while the presence of bush accessions is relatively uncommon. Most of the Madrilenian landraces have a remarkable fitness for green-pod consumption (42 %) and their seeds are mainly white (30 %), ovate-shape (49 %) and medium-large (40 %). The study of seed storage protein allowed to classify the landraces according to their domesticated gene pools. Most of them (72 %), with T and C phaseolin type, seem to belong to Andean germplasm, while the remaining (28 %), with S and B phaseolin type, to Mesoamerican one. The remarkable morphological diversity of common beans found in this small area is a symptom of a broad genetic base despite genetic erosion, what indicates a widespread crop in the past. Therefore, it is advisable to design agro-environmental policies to promote the production and commercialization of common bean landraces in Sierra Norte of Madrid. © 2013 Springer Science+Business Media Dordrecht.
