Danial D, Nurbani. 2015. Study on promising lines of upland rice in East Kalimantan. Pros Sem Nas Masy Biodiv Indon 1: 910-913. To date, the national rice production is focused on irrigated land, especially in Java. While the contribution of dry or upland rice fields spread across various islands of Indonesia is still very limited. Upland rice farming has a positive value in supporting of national food security, because of the earlier harvest season, when the rice stocks in the market are depleting. The idea that upland rice is less environmentally friendly, can be corrected by the application of sustainable green landscape planting (permanent green landscape) based on upland rice. The aim of this activity was to get candidates promising lines of upland rice that had high yield potential and specific location. The study was conducted in the Village of Bukit Harapan, Samboja, East Kalimantan. The activities were carried out using a Randomized Block Design (RBD) with three replications. The results showed that of the six planted strains were obtained two strains that had higher yields than Towuti and Situ Bagendit as check varieties, i.e. SHS 126 and SHS 125 with an average yield was 2.27 t/ha and 2.03 t/ha, respectively. Based on the empty grains per panicle there was no significant difference. The lowest number of empty grains per panicle was SHS 126 (13.27) and SHS 127 (16.60). Meanwhile, the highest number of filled grain per panicle was SHS 126 (118.33), SHS 125 (113.00) and SHS 127 (105.13). At a weight of 100 grains, SHS 126 has the highest weight (2.59 g) and was not significantly different with SHS 125 (2.58 g) and SHS 126 (2.59 g), but significantly different with Towuti. SHS 126 and SHS 125 had an adaptation that was pretty well with an average yield of 2.27 t/ha and 2.03 t/ha higher than Situ Bagendit and Towuti.
