Abstract

Correlation and path-coefficient analysis were carried out for twelve different quantitativetraitsin a population of forty six genotypes of ashwagandha(W. somnifera). The analysis revealed strong positive association of dry root yield per plant with root diameter, root length, plant height, root branches and days to maturity. The plant height and root branches per plant had positive direct effect on dry root yield per plant. Hence, plant height and root branches per plant may be good for improvingdry root yield per plant through selection in ashwagandha.
