its Components and Resistance to Charcoal Rot (Macrophomina phaseolina)]]>MahmoodTalatSyed Sadaqat Mehdi112003211Mean squares from analysis of variance revealed significant differences among S_{1} and
S_{2} progenies evaluated for seed yield, its components and resistance to charcoal rot
disease. Mean, range and coefficient of variation indicated that S_{1} and S_{2} progenies of
"UAF" random mated sunflower population contained larger amounts of variability for
all traits. The estimates of genotypic variance were smaller than their corresponding
phenotypic variances, revealing presence of environmental components. The genotypic
variances among S_{1} and S_{2} progenies were significant for all the traits evaluated by
testing with their respective standard error. The estimates of environmental variances for
indicated traits among S_{1} and S_{2} progenies remained low in value compared to their
respective genotypic and phenotypic variances. The estimates of broad-sense heritability
for all the traits evaluated were comparatively greater among S_{2} progenies. However, the
heritability of all plant traits when tested with their respective standard error when found
to be significant for both S_{1} and S_{2} progenies.]]>Adefris, T., H. Jayaramaiah, S. Ramesh and A. Teklewold,1999Helianthus annuus L.).]]>Andrei, E. and B.
