Abstract
The aim of this research was to examine the yield characters of peanut in drought stress. The experiment was conducted by usingof peanut cv. Kelinci that is sensitive genotype as female parent and US 605 which is tolerant genotype as male parent, including theF2 population F1 off spring from hybrid cv. Kelinci (P1) with US 605 (P2). The number of pods, amount of fi lled pods, dry weightof pods, dry weight of seed, the number of seeds, are measured during harvest. Expression of all yield characters were infl uenced bygenetic factor, except the variable weight of seed. All of yield show the quantitative and qualitative characters. The result analysis ofMendelians genetic yield showed all characters were controlled by 2 until 3 gene with the dominant and resesif epistasis combinationpattern. Result from joint scalling test analysis showed all variable were not only determined by additive and dominant infl uence butalso by genetic interaction. Additive infl uence with the high narrow sense heritability most of all variables together can give opportunityto obtain tolerant peanut line with heigh yield.
