Abstract:
To find out genetic variability,
heritability, and trait association among yield
and yield-related traits among bread wheat
genotypes, an alpha lattice design was used in
triplicate manner where 50 wheat genotypes
were evaluated at the University of
Agriculture Peshawar during rabbi growing
season 2021-22 along with a regional check
genotype. Data were taken on ten parameters.
All the genotypes showed significant
variation among them, signifying the
possibility of enhancing genetic improvement
through breeding programs. Highly significant
differences were found in days to heading,
days to maturity, plant height, spike length,
grain filling duration, number of grains per
spike, biological yield and grain yield these
traits indicating diversity in yield potential.
Moderate to low heritability values were noted
for most of the traits. The study exhibits
positive correlations for plant height with
grain yield, spike length with biological yield
and harvest index with grain yield. On the basis
of high heritability and positive correlation of
grain yield with other traits, it is recommended
that G-41, G-3, G-12, G-37, G-34 and G-14
genotypes which have the potential to be
incorporate in further breeding programs.
