Item Caracterización morfoagronómica de 14 accesiones de trigo duro (Triticum turgidum L. (thell) durum) en la localidad de Laguacoto III, cantón Guaranda, provincia Bolívar(Universidad Estatal de Bolívar . Facultad de Ciencias Agropecuarias . Escuela de Ingeniería Agronómica, 2015) Flores Tacle, Juan José; Monar, CarlosThe hard pea under the different consumption forms is one of the most important cereals in the feeding human, this consumption it has been increased notably due to the population’s quick growth, excellent for its high content of protein and carbohydrates, used in industries. In the Ecuador, they don’t have varieties of hard wheat; the program of investigation and Production of Seeds come carrying out an investigation process with germplasm of hard pea coming from INIAP. The objectives outlined in this investigation were: i) To evaluate the main characteristic morphological and agronomic of 10 accessions of hard pea and a control (Arveja Rosada Chillanes). ii) To select the best accessions of hard pea for the area agroecological in study. iii) To generate a database of characterization and evaluation of 11 promissory lines of hard wheat that serve as base for future commercial varieties of hard pea. The present investigation was carried out in the town of the Laguacoto II canton Guaranda, Province Bolívar; a design of complete blocks was used at random with 11 treatments and three repetitions. They were carried out variance analysis, correlation, lineal regression and test of Tukey to 5% to compare the averages of accessions. The main results obtained in this investigation were: the yield higher average, registered in the accession T8: INIAP-435 Blanquita with 4.778 Kg/ha and dry T11: Arveja Rosada Chillanes with 2.431 Kg/ha. Variables that decreased wheat yield were more delayed and higher incidence of Virus (BYDV) accessions. There was positive correlation between grains / spike, grain weight and quality versus yield. Of the analysis nutritional proximal, the indicators of protein, they are appropriate for the industry of pastas, noodles, semolina and cookies with 12,91% protein and 17,6% of humid gluten. Finally this study allowed to select eight accessions of hard wheat (Annexed No 9) with good characteristic morphological, agronomic and nutritional to continue with the process of investigation participative and to liberate to medium term commercial varieties of hard wheat with a high yield potential and industrial quality, to mitigate climate change and contribute to food security
