Genetic variability is an essential feature for selection among the genotypes for breeding programs. The current study was conducted in 2019 using a Randomized Complete Block Design with two replications to identify genetic variation among soybean landraces. Data were recorded on a set of 38 genotypes for, days to flowering, days to pod initiation, pods plant^-1, plant height, primary branches plant^-1, days to maturity, 100-seed weight and seed yield plant^-1. Significant differences were observed among all the landraces for all the traits. Among the landraces early flowers initiated (44.0 days) for K2uk54, whereas K2p84 was late in flowering (54.5 days). Early pods were initiated (86.5 days) in K2uk61 and late (101.5) was observed for K2w23. Short stature plants (53.1 cm) were observed in K2p20, while K219 were taller ones (91.5 cm). Line K2p28 was recorded minimum number of pods plant^-1 (31.7), while line K2uk45 had maximum number of pods (67.0). Lines K2p99, K2p28 and K2p84 had minimum primary branches plant^-1 (5.0), while line K2uk54 had maximum primary branches plant^-1 (13.0). Line K2uk44 and K2p87 were earliest in maturity (180.5 days), while line K2p75 was late in maturity (196.5 days). Minimum 100-seed weight (6.0 g) was recorded in K2p75, while maximum (12.8 g) was recorded for K2w30. Minimum seed yield plant^-1 (7.32 g) was observed in K2pa3, while maximum seed yield plant^-1 (14.52 g) was recorded for K2uk45. Analysis revealed low, moderate and high heritability for the studied traits. High heritability was recorded for days to maturity (86%) and 100-seed weight (65%). Moderate heritability was noted for days to flowering (30%), plant height (34%), pods per plant (46%) and seed yield per plant (45%), while low heritability was recorded for days to pod initiation (29%) and primary branches per plant (13%). The current study revealed that the landraces K2uk45, K2p133 and K2uk154 could be used in future breeding programs to produce high yielding soybean cultivars in Peshawar region.
