Abstract

The association of traits that may exist between or
among sorghum characters is essential for breeders. Therefore, the present
study is aimed to analyze and determine the traits having greater association
with yield utilizing the correlation and path analysis for different traits of
early and medium maturing lowland adapted Ethiopian sorghum genotypes. A total
of 110 early and medium maturing sorghum genotypes were used in alpha lattice
design which is replicated twice at two locations in 2016 cropping season.

The
results of correlation analysis suggested that the magnitude of genotypic
correlation coefficients  were  higher 
than  the  corresponding phenotypic correlation
coefficients for most of the traits 
suggesting  that  there 
was inherent relationship 
between  these  traits. 
Grain yield showed significant and positive phenotypic correlation with
number of heads per plot (r=0.34**), panicle weight (r=0.19**) and hundred
grain weight (r=0.21**). The strongest phenotypic association was observed
between days to flowering and days to maturity (r= 0.53**) followed by hundred
grain weight and plant height (r= 0.47**). In addition path  coefficient 
analysis  provides  an 
effective  means  of 
finding  direct  and indirect 
causes  of  association
.
