Path-coefficient analysis of seed yield and its components in linseed (Linum usitatissimum L.) - A review

In this article we have reviewed the works on path coefficient analysis of seed (grain) yield and yield contributing characters in linseed under normal sown, late sown and soil stress conditions. The dependent variable was seed yield, and independent variables were yield contributing characters such as days to 50% flowering, days to maturity, plant height, technical height, tiller number, number of primary and secondary branches, number of capsules, number of seeds per capsule or plant, 100 or 1000- seed weight, etc. Under normal sown condition, mostly number of capsules is the trait that has very high or high positive direct effect on seed yield across different sets of plant genetic resources and environments conferring it to be the most important selection criterion for improvement of seed yield. Under late sown condition, basing on different plant materials number of capsules is the most promising selection criterion for improvement of seed yield. Path analysis work under soil stress condition is inadequate.
