Caracterización morfoagronomica de 299 accesiones de mani (Arachis hypogaea L.) del germoplasma del INIAP - Ecuador en Tumbatú Carchi

Abstract

La presente investigación se llevó a cabo en campo, la caracterización morfoagronómica de la Colección Nacional de maní (Arachis hypogctea L.), se efectuó en Tumbatú Carchi, que entre sus características agroecológicas presenta una longitud de 77°59’882” W, una latitud de 0°29’166” N, está ubicada a 1650 msnm, oscila en una temperatura media anual de 24 °C y una precipitación promedio anual de 714 mm.

The present investigation was carried out in field, the characterization morfoagronómica of the National Collection of peanut (Arachis hypogaea L.), it was made in Tumbatu Carchi that its characteristic agroecológicas enters it presents a longitude of 77°59'882" W, a latitude of 0°29'166" N, it is located to 1650 msnni, it oscillates in an annual half temperature of 24 °C and a precipitation I average yearly of 714 mm. It was characterized 299 peanut agreements that were collected in the three regions of the Country; Costa, Amazonia and something of the Serranía, 32 morphological describers were used as agronomic that were analyzed with the statistical package S.A.S. obtaining a womb of similarity of genetic distances through the alogaritmo of Gower that analyzed with the cluster of Ward a Dendrograma he/she revealed conformed by four groups, nine subgrupos and 42 morfotipos that are inside the mentioned groups determining this way a narrow relationship among each one of the agreements.
