Seed cotton yield and fiber quality traits are
controlled by many genes and also greatly affected by biotic and abiotic
environmental factors. Hence, selection based on only yield would not be
effective. In order to improve the yield potential of the cotton cultivars,
an understanding of the relationship among various traits is of more
importance. The current research was aimed to determine and record
phenotypic and genotypic variation of elite cotton lines for utilization of
the information in the breeding program to enhance cotton crop productivity
and production in Ethiopia. Thus, 14 genotypes, five rows each, were
evaluated in three replications at Homosha district of Benishangul-Gumz. The
results depicted significant differences (P ≤0.05) among the varieties for
all the studied traits, exhibiting the availability of substantial genetic
variability among the cultivars for studied traits. Hence, these promising
cultivars can further be exploited in various breeding programs to improve
various characters of the cotton genotypes. Furthermore, correlation
analysis showed that sympodial branches plant-1, boll weight and bolls
plant-1 made significant and positive associations with seed cotton yield
plant-1. Thus, selection for these traits will ultimately enhance the
chances of increasing seed cotton yield plant-1. High heritability estimates
were found for all studied traits with the exception of monopodial branches
plant-1, indicating that these traits were inherited together and direct
selection may be proved to be useful for these traits.
