Variability and association studies for morphological and biochemical traits in potato (Solanum tuberosum L.)

Published on

Potato (Solanum tuberosum L.) is one of the most
important food crops after rice, wheat and maize. This
world-crop has historically contributed to securing the
food and nutrition and avoiding poverty and hunger. In
the emerging global economic order in which agricultural
crop production is witnessing a rapid transition to
agricultural commodity production, potato is appearing
as an important crop, poised to sustain and diversity
food production in this new millennium. The identification
of genotypes with high variability and heritability for agromorphological characters is the pre-requisites of
breeding programme. Partitioning of variance into
various components provides information regarding
breeding value and nature and magnitude of variability
in the expression of a particular trait. The polygenic
characters and its components are highly influenced
by environment and become difficult to know whether
the variability is heritable or environmental. Therefore,
the present investigation is carried out to gather
information on magnitude of variability in potato under
two different environments.
