GENOTYPIC ASSOCIATION AND PATH COEFFICIENT ANALYSIS IN ASHWAGANDHA (WITHANIA SOMNIFERA)

Published on Nov 02, 2019 03:06 AM

Genotypic and phenotypic correlations and path coefficient for seven characters were
studied in 36 early generation selections in F2 population of wide crosses (WS 20 X Wild
and WS 22 XWild) and seven genotypes of ashwagandha. Results indicated that root yield
was significantly and positively correlated with plant height, stem branches, root length,
root diameter, root branches, and seed yield. All the component characters studied were
significantly and positively associated among themselves, except root branches with seed
yield. Path coefficient analysis showed highest positive direct and indirect effect of plant
heightand stem branches on root yield. Indirect effects ofothercomponent characters were
high through plant height and stem branches on root yield. Selection for high plant-height
and stem branches appeared to be useful for improving root yield.

Keywords: Correlation coefficient, path coefficient, Withania somnifera.
