Abstract
The present investigation entitled “Exploration of genetic variability in turmeric (Curcuma
longa L.) under low hills of HP” was carried out at Vegetable Research Farm, Department of
Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (HP) during rainy season,
2019. Twenty one genotypes including check variety Palam Pitamber were evaluated in Randomized
Complete Block Design with three replications to ascertain extent of variability, heratibility, genetic
advance and gain, correlation and path coefficient analysis for yield and other horticulture traits
among the genotypes. Analysis of variance showed significant differences among all the genotypes
for all the characters under study. Three genotypes namely LC-T-20-18, LC-T-9-18 and LC-T-12-18
were found to be high yielding as well as better from consumer’s point of view. They could be the
promising parents for utilization in further breeding programmes. Moderate PCV and GCV existed
for weight of mother rhizome length of mother rhizome, girth of mother rhizome, number of
primary fingers per plant, number of secondary fingers per plant, number of leaves per plant,
curcumin content, dry matter content and yield per plot. High heritability estimates were observed
for curcumin content, plant height, weight of mother rhizome, leaf length, dry matter content, leaf
breadth, length of mother rhizome, number of primary fingers per plant, girth of primary rhizome,
number of leaves per plant and girth of mother rhizome while high estimates of genetic gain were
observed for weight of mother rhizome, length of mother rhizome, number of primary fingers per
plant and girth of mother rhizome. The correlation studies at phenotypic and genotypic level
revealed that 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 had positive and direct effects on yield per plot.
