Evaluación de la adaptabilidad de híbridos de pepino (Cucumis sativus L.) bajo cubierta, en el sector de Sigsipamba de la parroquia Picaihua.

Abstract

The research work was carried out with the objective of evaluating the agronomic adaptability of four cucumber hybrids (Cucumis sativus L.) under cover in the province of Tungurahua, canton Ambato, Sigsipamba sector, the geographical coordinates latitude South 1°15'28,4202''and longitude West 78°33'46,18044''altitude 2598 m.a.s.l. A Randomized Complete Block Design (RCBD) was applied, with four treatments and three replications, the Tukey test at 5% was applied to the significant responses for the treatments, where the results obtained for the variable number of flowers, 45 days after transplanting, there were no significant differences between treatments. Similarly, in the variable yield per plot, 45 days passed from planting to the first harvest, since the hybrids are homogeneous and had the same conditions of management and climate, being a short cycle crop with a duration of two months: plant height, stem diameter, fruit length, fruit diameter, fruit weight, where the best agronomic characteristics were obtained in the Taurus hybrid with a stem diameter of 10.62 mm, plant height 139.80 cm, yield percentage of 96.67%, fruit diameter of 60.72 mm, number of flowers 12.90 flowers, fruit length 23.24 cm, fruit weight 459.75 g. On the other hand, the hybrid with the highest productive potential under greenhouse conditions was Taipan, which presented the highest yield with 39.20 kg. The hybrid with the lowest yield was CU 700417. Keywords: Cucumber, Hybrids, Treatments, Adaptability.
