Adaptación de setenta y dos líneas promisorias de cebada maltera (Hordeum vulgare L.) accesión 01 – 2019 ABE InBev en la granja experimental Tunshi, cantón Riobamba.

Abstract

The aim of this study was to evaluate the adaptation of seventy two promising lines of malt barley (Hordeum vulgare L.) to the agroclimatic conditions of the Tunshi Experimental Farm, Riobamba canton. A Randomized Complete Block Design with seventy two treatments and three replications was used. Lines 14, 34, 11 and 48 showed the best adaptability to the agroclimatic conditions in Tunshi, which was reflected in their agronomic behavior. Line 14 showed the best results in days to heading with an average of 62, 67 days, line 34 got an average of 100.33 days in days to physiological maturity. Line 11 got an average of 837.67 plants in the number of established plants. Line 34 got the highest number of spikes with an average of 255.33 effective spikes. Regarding the plant height, line 14 got the highest height with an average of 94.63 cm. The line 48 got the longest spike length with an average of 10.40 cm. For the number of tillers per plant, line 14 got an average of 11.33 tillers. Regarding the incidence and severity of disease attack (Roya), lines 14 and 48 got the greatest resistance to the attack of this disease. The line 11 showed the highest number of grains per spike with an average of 37.67 grains per spike. The line 48 showed the highest yield with an average of 2.87 t/ha. It is concluded that lines 14, 34, 11 and 48 adapted to the agroclimatic conditions of the Tunshi Experimental Farm. From the identified lines, it is recommended to continue validating and evaluating the agronomic characteristics that they present to determine the best lines based on tolerance and adaptability.
