Storage of seeds of agricultural interest in the germplasm bank and agronomic evaluation in the field

Abstract

The research was carried out in the Department of Germplasm of the Technical University of Cotopaxi Extension La Maná, its objective is to evaluate the viability of eight types of seeds of plants of agricultural interest such as Rocha Beans, Concepción Beans, Mirador Wheat, Maize native kanguil, Chimborazo Wheat, Urcuquí Bean, Gema Bean and Rye, which were stored for a period of six years and at 4°C. The samples were extracted and evaluated every two years (2016, 2018 and 2022) counting their germination percentage and moisture content and dry matter at the beginning and at the end of the experiment, the agronomic characteristics of the crop were also evaluated at the end, such as height of plant, number of leaves, pods per plant, weight of 100 seeds (g) and yield per hectare (kg). The experimental design that was used was the completely randomized design (DCA) with eight treatments and four repetitions, with Tukey's multiple range test at 5% error and the data were processed in the Infosthat statistical software. At the end of the experiment, it was obtained that only three varieties of beans were suitable for storage, among them: urcuquí, rocha and gema, which corresponds to 37.5 %, maintaining their germination power for six years in the cold at 4°C.
