  Abstract
  Seed traits (Seeds per capsule, thousand seed weight and Seeds-husk ratio) and oil content were influenced by prevailing environmental conditions during maturity and post flowering period. A study was executed to document the influence of capsule position on seed traits and oil contents of linseed. The seeds of linseed (Linum usitatissimum L.) cultivar L-6 were sown during month of October, 2009. Prior to appearance of flowers at terminal node, 300 plants were selected (100 plants in each replication) in three replications. On the appearance of first capsule on terminal node labeling to take capsule samples from different positions of plant was done on the day of emergence. The treatments were twelve (Label-1 to Label-12) and it was based on the appearance of capsules on different dates. Capsules labelled on each position were harvested and thrashed separately. Seed traits like seed per capsule, thousand seed weight, seed-husk ratio and oil content were recorded from harvested capsules separately. The maximum seed per capsule (9.05) was recorded for the first label and it decreased significantly for the last label (6.01).This might be due to strong relationship between first sink with source compared to last where plant might requires more ATP to build source-sink relationship. Similar results were obtained for thousand seed weight, seed-husk ratio and oil accumulation. Therefore, it can be concluded that capsule position has significant effect on seed traits and oil contents of linseed that could be due to differential partitioning of photoassimilate at different points of capsule. In addition consistent decrease in values of above parameters may have been caused due to weaker source-sink link and competition for assimilates.
