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.
