Correlation and path coefficient analysis studies in turmeric (Curcuma longa L.) under low hills of Himachal Pradesh
The research titled “Correlation and path coefficient analysis studies in turmeric
(Curcuma longa L.) under low hills of Himachal Pradesh.” was carried out in Dr. YSP
University of Horticulture and Forestry, Solan (H.P). The experiment was laid out in
randomized block design comprising of 21 diverse genotypes of turmeric, to ascertain the
correlation and path analysis for yield and other horticultural traits among the genotypes. The
correlation coefficient studies showed that yield per plot had positive and significant
association with number of leaves per plant, number of tillers per plant, length of mother
rhizome, weight of mother rhizome, length of primary rhizome, girth of primary rhizome,
length of secondary rhizome and girth of secondary rhizome. Path coefficient showed that the
weight of the mother rhizome, girth of the primary rhizome, girth of mother rhizome, leaf
length, number of leaves per plant, dry matter, number of secondary fingers per plant and
girth of secondary rhizome had a high positive direct effect on yield per plot. Hence, these
characteristics should be given more helpful in the selection program of high-yielding
genotypes in turmeric.
