GABRIEL, Julio; ANGULO, Ada; VELASCO, José  and  GUZMAN, Ruth. Adaptation of indeterminate tomato hybrids [Solanum lycopersicum L. (Mill.)] under greenhouse conditions. J. Selva Andina Res. Soc. [online]. 2016, vol.7, n.2, pp.47-65. ISSN 2072-9294.

Were evaluated 11 hybrids of indeterminate tomato company by ENZA ZADEN and a witness of the company SEMINIS, under greenhouse and laboratory with the objectives of: i) evaluate and participatory select 11 new hybrids of indeterminate tomato company ENZA ZADEN by adaptation, agronomic and health in the crop cycle, in harvest and post-harvest and ii) implement farmers with entrepreneurial characteristics, business participatory hybrids selected indeterminate tomatoes. The results showed that varieties with higher number of fruits and yield were Shannon and Afamia between type beef (round) and Granadero between pears. The round varieties had a higher average yield of pears. Pears are a number of varieties had higher than average round fruits. There was a high positive correlation between the number of fruits and yield both pears and round. The varieties with higher fruit weight were Bruni (between the round) and Centenario, Granadero and (from pears). Fruit weight in time is reduced linearly for all varieties except Corleone. The round variety with greater firmness fruit was Shannon. There was no difference in firmness between the pears. The firmness of fruit reduced linearly time for Bruni, Elpida, Hechicero, Rally, Centenario, Corleone and varieties and reduces linearly but increases quadratically for Maradona and Shannon varieties. The varieties that reduced fruit firmness were slower Corleone, Centenario and Afamia. The varieties with lower pH were Afamia (between the rounds) and Centenario and Granadero (from pears). The pH increases over time in linear form in all varieties. The varieties with higher content of Brix were Hechicero, Afamia, Granadero, Elpida, Rally, Maradona and Sebatina (between the rounds) and Corleone (from pears). Brix content increases linearly over time in all varieties. There were high and positive significant correlations between Brix and pH; weight and firmness of fruit. Participatory selection of varieties Elpida, Rally (round),  Centenario and Policarpo (Pears), which are now commercially that, are taking place in the greenhouses of El Paso in Cochabamba was achieved.
