La Selva to obtain a hybrid with tolerance to the fruit borer Neoleucinodes elegantalis Guenee (Lepidoptera: Crambidae) and to the nematode Meloidogyne incognita (Kofoid & White) (Nematoda: Heteroderidae), to obtain better-adapted plants to the conditions of the Colombian coffee-growing region and with bigger and non-dehiscent fruits. La Selva cultivar is a hybrid developed from the interspecific backcross of Solanum quitoense Lam. × Solanum hirtum Vahl with plants of lulo cv. Castilla Larga Vida. The experiment was conducted in the municipality of Dosquebradas, Risaralda, Colombia, located at 1,465 m a.s.l. F1 plants were obtained from reciprocal crossings. When inoculated with the nematode M. incognita, plants showed susceptibility in their seedling stage; however, when we carried out the evaluation six months after transplantation under field conditions, nematode infestation was less than 1%, which likely indicates the tolerance of these materials to the nematode. When assessing the resistance of the hybrid to the attack of N. elegantalis, we found that the evaluated materials were resistant to this insect. The resulting hybrids showed good agronomic characteristics, such as a good morphological structure and vigor, high productivity, good solar exposure adaptation, large fruits (5.6 cm average diameter) similar to those of cv. Castilla, with yellow peel, green pulp and non-dehiscent fruits with pleasant aroma and flavor. As an undesirable characteristic plants had thorns on leaves and stems.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"19 1","pages":"351-366"},"PeriodicalIF":0.2,"publicationDate":"2018-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21930/RCTA.VOL19_NUM2_ART:520","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42377679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the Hub extension model of the governmental program MasAgro seeks to be a space in which maize farmers, extensionists, suppliers of inputs, government, teaching and research institutions, among others, interact with each other to generate individual and collective well-being through innovation. The objective of this work was to analyze the relational structures within the Hubs. To this effect, direct interviews were applied to 457 actors from 10 agroecological regions that make up the Hubs of the maize system in Mexico. The indicators of density, closeness, transitivity and diversity of relationships were measured in two moments of analysis: baseline and final line, through the methodology of analysis of social networks. A \"t\" test of related samples revealed that for the first three indicators there is a statistically significant difference between moments analyzed (p <0.05), which indicates that the interaction between the actors has been managed in the Hub, placing it as a space in which local structure has been generated and relational capital has been maintained, bases of social capital necessary for the development of innovation processes in the rural sector. These findings may serve program managers and policy makers as a complementary tool for evaluating intervention strategies in the sector.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"19 1","pages":"15-28"},"PeriodicalIF":0.2,"publicationDate":"2017-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21930/RCTA.VOL19_NUM1_ART:609","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49356346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But the implementation of crosses with creole breeds appears as an option to introduce genes that provide adaptability to herd animals. The aim of this study was to compare productive parameters between Holstein and their crosses with the Blanco-Orejinegro creole breed in different proportions of both races. Hundred and twenty-five lactations of 48 cows from a herd in Antioquia were used. Mixed models of repeated measures were adjusted including fixed effects of birth number, genetic group and contemporary group. Linear regression models were used to evaluate the effect of the percentage of the creole race on production parameters. The genetic group had a significant effect on peak production, total production and production at day 150. Pure Holstein showed a higher performance than crossed animals in milk production (=6,853.48 L), in peak production (=34.65 L) and in day 150 production (= 19.97 L). The linear regression analysis showed a slight tendency for productivity to decrease as the proportion of Blanco-Orejinegro increases. Although the use of crossbred animals in specialized dairy systems can reduce productive parameters in the herd, it can also allow the introduction of genes that contribute to adaptation to the environment and to diseases resistance.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"513-527"},"PeriodicalIF":0.2,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41607174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Pareto diagram and a response surface plot were generated in order to know the significant influence that the study variables have on protein production. The results showed that higher biomass production (3.72 g/L for the culture with acetate and 2.17 g/L for the one with carbonate) are directly related to sodium nitrate (1.96 mM) and potassium phosphate (2.11 mM). In addition, the maximum protein values obtained were 60% and 34% for acetate and carbonate cultures, respectively, both with 2.94 mM of sodium nitrate. Finally, the Pareto diagram showed that for the culture based on acetate there was no significant variables that influenced protein production; whereas the culture with carbonate, sodium nitrate and potassium phosphate influenced significantly the production of this metabolite.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"451-461"},"PeriodicalIF":0.2,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42264794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried in the crop year 2013/2014 for a crop that was implanted in the year 2012, where yield components of heart palm and the soil´s physical attributes were analyzed at a depth of -0.10 m, using a grid with 54 georeferenced points. Three multivariate methods were used: hierarchical clustering, non-hierarchical clustering (k-means) and principal components analysis (pca). The k-means analysis showed larger heart palm stem diameter values in the group of points with higher mechanical resistance to penetration values, and lower gravimetric soil moisture values. The PCA showed that the first two principal components (CP1 and CP2) explained 68.29 % of the variations of the original data set, where soil density and total porosity showed the largest discriminatory power in CP1, and only stem diameter showed significant discriminatory power in PC2. Multivariate statistics was efficient in the discrimination of the physical variables of the soil studied that have a greater relationship with the morphological components of the heart palm plant.","PeriodicalId":41142,"journal":{"name":"Revista Corpoica-Ciencia y Tecnologia Agropecuaria","volume":"18 1","pages":"543-554"},"PeriodicalIF":0.2,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46828608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this reason, the aim of this study was to identify through participatory methods, indicators that allow the design of a monitoring and an assessment system to guide the public policy on this issue. In order to identify the indicators, 18 participatory workshops were carried out in the subregions of the department of Antioquia, Colombia. As a result, 39 indicators were identified and later selected to assess the nine criteria established by the legislation; these were also validated and adjusted based on the experiences of the technical assistants who provide the service throughout the municipalities.

In order to evaluate the quality in which the fruit is commercialized, physicochemical parameters as pH and soluble solids concentration (°Bx) were measured. The skin and pulp pesticides analysis in both fruits was performed using gas chromatography with microelectron capture detection (GC-μ-ECD), and employing solid-phase extraction techniques as sample pretreatment. The result of the chromatographic analysis showed the presence of 10 different op and oc pesticides both in the skin as well as in the pulp of both fruits, some of them in higher concentrations than 0.13 ppm for tomatoes and 0.39 ppm for gooseberries. The results found in this study suggest the high residuality of these substances, revealing the disproportionate use of these pesticides in the cultivation of consumer crops as tomatoes and gooseberries.

As a result, the flour was found to be a source of bioactive compounds, showing total phenol concentration (23.40±1.30 mg gallic acid/100 g), antioxidant activity (33.10%±3.20), total carotenoids (59.31±1.61 mg β-carotene/100 g), color a* (4.95±0.58), color b* (3.25±0.57), and luminosity (33.95±3.16). On the other hand, there was a high level of total carotenoids (85%) and phenolic compounds (94%) retention after six months. Additionally, color change showed no significant difference during storage. In conclusion, the flour obtained is a byproduct with properties that can be used as an alternative to agroalimentary substitutes, mainly due to its color and antioxidant activity attributes.
