Adaptación de setenta y dos líneas promisorias de cebada maltera (Hordeum vulgare L.) Accesión 02 – 2019 ABE InBev en la granja experimental Tunshi, cantón Riobamba.

Abstract

The aim of this investigation was to evaluate the response to adaptation of the 72 lines of malt barley, using a Randomized Complete Block Design with seventy two treatments and three replications. Parameters, days to emergence were also evaluated and all the lines had an emergency at 10 days. Regarding the parameters of days to heading and days to physiological maturity, the lines 63 and 39 showed the best results with an average of 64 and 61.67 days , and 102.33 and 103.33 days respectively. In the parameters, number of tillers per plant, number of grains per spike, the lines 39 and 8 showed the best results with 4.33 and 6.00 number of tillers per plant and for number of grains per spike it was 28 and 28.33 grains. Regarding the parameters of plant height, spike length, the line 62 showed the best results with an average of 93.17 cm and 11.60 cm respectively, for the case of incidence and severity at disease attack (Roya) lines 8 and 62 showed the best responses, being categorized as resistant and moderately resistant respectively. Lines 39, 8 and 22 showed better values in terms of yield T/ha with an average of 3.2 T / ha corresponding to line 39, whereas lines 8 and 22 had an average of 3.00 T / ha for the 2 lines. It is concluded that lines 39, 8 and 22 showed the best results in terms of adaptation in the Tunshi Experimental Farm. It is recommended to continue validating and evaluating the agronomic characteristics they show in order to determine the best lines based on tolerance and adaptability.
