- Abstract
Peanuts in Indonesia are mostly grown in Java, and other distributed in Sumatera, Kalimantan, and Papua which is dry and acid soil. This land is very diverse and has potential for agricultural production, especially intensification for food crops. Therefore specific varieties for these environments are necessary. Several field experiments were conducted in the dry seasons of 2011-2012 in 8 acid environments sites of Lampung Province, using a randomized block design with 3 replications. The research materials included 18 breeding lines from crosses and local varieties, and 2 checks of improved varieties (Jerapah and Talam 1). Stability analysis for pod yield was performed using regression technique and AMMI methods. Genotype G16 are stable according to regression and AMMI method and relatively stable to environmental changes. Stability analysis based on 3 stability parameters (mean yield, linier regression, and deviation from regression) and biplot graph indicated that the genotype G2, G3, G4, have stability below average followed with pod yield above general mean, and adapted on environment E1, E5 (favorable environments). Among those lines, genotypes G3 and G4 had the highest pod yields potential 4.05 t ha-1 and 3.73 t ha-1, with an average yield 2.5 t ha-1 and 2.6 t ha-1 dry pod, respectively. These lines have been released as new varieties tolerant to acid soils.
