Abstract Flax Linum usitatissimum L is an seed crops that its oil is used in differentindustries and as edible oil Improvement of the seed and oil yield in flax iseconomically important and the genetic potential of adapted landrace varieties can beused in breeding programs In order to investigate the genetic variability for theagronomic traits in landrace varieties of flax for single plant selection and isolating thebreeding lines this study was conducted at the research farm of Isfahan University ofTechnology in 2005 A randomized complete block design with four replications wasused Six landrace varieties collected from Khorasan Kordestan Shahreza Ahvaz Semirom Chaharmahal Bakhtiary regions and the Flanders cultivar from Canadawere evaluated to assess inter and intra population variation of agronomic traits Therewas a significant difference among the populations for all the studied traits such ascapsules plant seeds capsule and 100 seed weigh The genetic coefficients of variationwas less or the same as the phenotypic coefficients of variation for most of the traitsindicating that most of the variation for those traits was due to the genetic factors Thehighest and lowest coefficient of variation was obtained for yield plant and oil yield respectively The populations also showed a high variation for the studied traits amongthe single plants within the population The highest intra population variation wasobserved for seed yield plant and capsules plant however the lowest variation wasfound for to 100 seed weigh Capsules plant had a significant and positive correlationwith seed yield plant however seed yield plot had a high and significant correlationwith days to maturity capsules plant and seed yield plant Oil yield had high andsignificant correlation with seed yield but it had no correlation with seed oil content The results of stepwise regression indicated that capsules plant and seeds capsule werethe most important component of seed yield and capsules plant seeds capsule and 100 seed weigh could explained 88 of the variation for seed yield plant The stepwiseregression also indicated that capsules plant seeds capsule and 100 seed weigh were themost important components of seed yield plant in most of the populations Based onpath analysis 100 seed weigh and plant height had more direct effect on seed yield plot But capsules plant had the most direct and positive effect on seed yield plant Inconclusion the existing genetic variation for most of the traits including the yieldcomponents indicated that selection can be effective to improve these traits andcapsules plant seeds capsule and 100 seed weigh can be used as selection indices toimprove the seed yield
