Genotype x environment interaction for pod yield and yield components of groundnut varieties in warm sub-humid climate and moderately acidic soil

Published on

Groundnut is an important oilseed crop of India. In
Orissa, it is grown in kharif season as rainfed crop and
in rabi season either under residual moisture condition
or under irrigated condition. More than 170 varieties of
groundnut have been developed and released by 2009
but the farmers prefer to grow varieties like AK 12-24
and TMV 2 for both the seasons which are about 70
years old. So it is necessary to identify new variety which
could perform more or less uniformly under both the
seasons. In view of the better expression of certain
characters under specific environmental conditions the
stability analysis helps to isolate genotypes adapted to
particular seasons [1]. Information about phenotypic
stability is useful for selection of crop varieties as well
as for breeding programmes [2-4]. The stability of yield
in different groundnut genotypes are ultimately imparted
through the stability of their different component
characters in additive fashion.[5]. Therefore, this study
was undertaken to evaluate groundnut varieties for
stability of their pod yield and component characters of
yield under both kharif and rabi seasons for two years.
