Abstract

Bangka Belitung is dominated by marginal lands, such as dry land, which can affect the productivity of groundnut by reducing groundnut yield. Increased groundnut yield in Bangka Belitung could be done by using drought tolerance genotypes. The objective of this study is to obtain groundnut genotypes tolerant to drought stress. This research was conducted at Experimental and Research Garden, University of Bangka Belitung, from January to March 2018. This research used experimental method with Split Plot Complete Randomized Design. It consisted of 2 main plot and 8 subplot levels. The main plot consists of 100% and 40% of field capacity used in drought stress assessment. Subplot consist of eight groundnut genotypes. These genotypes were Bangka local groundnuts (Belimbing, Arung Dalam, Air Ketimbai 1, Bedeng Akeh, and Lubuk Kelik accession), and national varieties (Tuban, Hypoma and Kancil varieties). Research result showed Bangka local groundnut genotypes tolerant to drought stress was Belimbing accession for 100 seeds weight character. National varieties tolerant to drought stress were Tuban and Hypoma varieties. Tuban variety showed drought tolerance through the following characters: root length, number of seeds per pod, root dry weight, and seed weight per plant. Hypoma variety showed drought tolerance on root length and number of seeds per pod characters. Tuban, Hypoma and Belimbing could be recommended for groundnut cultivation on dry land.
