PATH ANALYSIS FOR QUALITY COMPONENTS IN LINSEED (LINUM USITATISSIMUM L.)

Published on

Path analysis for eight quaIity components was worked out in 22 linseed varieties tested in
two fertility conditions. StatisticaI analysis was done in four ways: (a) oil dependent and
other contributing characters, (b) protein dependent and othercontributing traits, (c) iodine
dependent and other contributing attributes, and (d) linolenic acid dependent and other
contributing fatty acids. In the path analysis of oil content, linolenic acid had a high
positive direct effect on oil content while protein content and iodine value exerted strong
negative direct effects on oil content under nonnaI fertility level. Under low fertility
conditions, all the contributing traits had a direct negative effect on oil. Similar pattern was
also observed in the path analysis of protein content. High positive effect of linolenic acid,
followed by linoleic acid and saponification vaIue, on iodine vaIue was observed. Stearic
and oleic acids affected directly and indirectly via other acids in negative way to the
linolenic acid. Under both the fertility levels, five fatty acids showed similar relationship.
