    Evaluación del comportamiento agronómico de 4 líneas promisorias de triticale (X Triticosecale Wittmack) generado por el INIAP, bajo condiciones agroecológicas de Querochaca
    (2023-09) Barrera Villena, Mayra Alexandra; Santana Mayorga, Rita Cumandá
    Triticale is a genetically improved cereal obtained by crossing wheat (Triticum) and rye (Secale) and was created for desert locations with poor soils and acidic pH. In Ecuador there are no triticale crops for commercialization due to the varieties released in the 80s that were not accepted, that is why this research has been carried out to identify its productivity and yield to reach the producers and motivate production, the which was carried out at the Technical University of Ambato, on the Querochaca Campus, whose purpose was the evaluation of the agroecological behavior of 4 promising lines of triticale and 1 control released by INIAP, to identify the material with the highest yield and best adaptability in said area, for which a completely random design was used with 3 repetitions for each of the promising lines and the control, generating a total of 15 experimental units with an area of 3m2 per plot. The variables to be evaluated were: plant vigor, growth habit, days to heading, plant height, type of straw, size of spike, number of grains per spike, yield, hectoliter or specific weight, weight of a thousand grains, type and grain color and diseases. The results were analyzed using tables and graphs obtained by the INFOSTAT software. It was shown that the 4 promising lines of Triticale and the control adapted to the agroecological conditions and no significant differences were found in the variables evaluated.

    Evaluación del comportamiento agronómico de cuatro líneas promisorias de cebada desnuda bajo las condiciones agroecológicas del sector Querochaca

    The research proposes the evaluation of the agronomic behavior of four promising lines of naked barley under the agroecological conditions of the sector of Querochaca, a completely random block design was used with 5 treatments and 3 repeats, variables such as days of tasseling, height of the thatch plant type, spike size, number of grains per spike, yield, specific weight, weight of thousand grains, type and color of grain and diseases that occurred were evaluated, for each of these variables the Shapiro Wilks, Homogeneity, ADEVA, 5% Tukey or qualitative test was performed. Concluding that all the promising lines provided by the program of Cereals in research were adapted under the agro-ecological conditions of the sector Querochaca canton Cevallos, in the province of Tungurahua. Obtaining promising lines much more outstanding than others, where CD-19-010 was the line that best adaptability in field presented with 81.67 days to the stem, intermediate stem, yield of 7483.33 kg/ha, specific weight of 78.90 kg hl -1 a coarse, large grain, well-formed, clean white and good looking. As for diseases that occurred were; yellow rust (Puccinia striiformis) had a percentage of 15%, leaf rust (Puccinia hordei) a percentage of 1% and yellow dwarfism virus of barley (Barley Yellow Dwarf Virus). Restricted yellowing of the leaves was found making it the best promising line compared to the remaining three lines (CD-19-007, CD-19-006, CD-19-011) and the control variety INIAP-ATAHUALPA 92

    Evaluación del comportamiento agronómico de cuatro líneas promisorias de avena bajo las condiciones agroecológicas de Querochaca
    (2023-03) Moposita Taipe, Alexandra Magay; Dobronski Arcos, Jorge Enrique
    Oats (Avena sativa) is a very important crop worldwide, in Ecuador this crop has come to have a good adaptation thanks to the geographical characteristics that it presents, the present investigation had the purpose of evaluating the agroecological behavior of 4 promising lines of oats in the sector Querochaca in order to determine which variety of oats has the best agroecological adaptation in the study place, in the Querochaca sector, 4 promising lines of oats and a control were cultivated, which was designed an essay with 3 repetitions for each of the variables, The variables that were taken into account were: Days to spike, plant height, type of straw, spike size, number of grains per spike, yield, hectoliter or specific weight, weight of a thousand grains, type and color of grain, diseases. For the results, they were analyzed using tables and graphs obtained by the INFOSTAT software. The appearance of the panicle in line AS-17- 002 was 109 days for which it was determined with a late promising line. Finally, it was possible to determine that the AS-17-000 lines have a higher yield and a better adaptation to the agroecological conditions of the area.

    Evaluación del comportamiento agronómico de cuatro líneas promisorias de cebada bajo las condiciones agroecológicas del sector Querochaca
    (2023-03) Naranjo Freire, Diego Alejandro; Dobronski Arcos, Jorge Enrique
    The present research work evaluated the agronomic behavior of four promising lines of barley, under the agro ecological conditions of the sector of Querochaca, the promising lines and the improved variety were provided by the INIAP cereals program, a completely random block design was employed with 5 treatments with 3 repetitions, in the research we studied variables such as days of tasseling, plant height, spike size, thatch type, number of grains per spike, yield, thousand grain weight, hectolithic or specific weight, type and color of grain and diseases, for each variable was used the test of Shapiro Wilks, homogeneity, ADEVA and Tukey to 5%, already finished the investigation the promising lines have been adapted to the agro ecological conditions of the field Querochaca in Cevallos canton, province of Tungurahua. Promising lines were obtained that stood out much more than others, the promising line CD-19-004 was the line that was better adapted to agro ecological conditions, presenting 85.33 days to the stem, plant height 125 cm, an intermediate stem, a medium grain, round shape, white color and good appearance, there was presence of diseases yellow leaf rust (Puccinia striiformis) with a severity of 38.8%, leaf rust (Puccinia hordei) present a severity of 6.67% and yellow dwarfism barley virus (BYDV) present traces of yellowing of the tip of few leaves, vigorous looking plant, CD-19-004 was the best promising line compared to the remaining three lines (CD-19-013, CMU-19-002, CMU-19-001) and surpassing the improved variety INIAP-CAÑICAPA 2003.
