Abstract

This Paddy (Oryza sativa L.) or rice as the main staple food, is very important food crop for the people of Indonesia. Germplasm or genetic resources (GR) is very important biodiversity and the basic capital needed in development agricultural industry including new varieties inventionin order to increase productionto support food security and sustainable agriculture. One type among upland rices in North Sumatra that widely planted by the farmersare the upland red rices. In order to conserve the extinction of these GR and to empower their cultivars, it is necessary to takeaction in more dynamic way of conservation such as in situ conservation (onfarm conservation) and ex situ conservation. The purpose of this study was to obtain information and data; agronomic, morphological, and production characteristics such as: plant height, harvest age, production per ha, weight of 1000 grains, shape, size, and color of unhulled grain and the hulled one (rice). The research was initiated with exploration activities in several districts in North Sumatra from January 2015 to April 2016 which included literature study, interviews and direct visit to farmer fields. Collection and storage for consolidation and characterization of upland red rice was conducted at Experimental Field and Screen House of Faculty of Agriculture UISU Medan. Results obtained; (1) Acquired 12 uplandred rice cultivars and most cultivars were found in areas of medium to high altitude, with flat topography, plateau tohilly;(2). All upland red rice cultivars showed good diversity in terms of agronomy, harvest age and production (2). Grain (lemma/palea) and seed (caryopsis) obtained were found to be variated in the shape, size, and color
