Genetic variability correlation and path analysis in some maize inbred lines

Abstract EN

The study was carried out at the field of College of Agriculture/ University of Duhok during spring and autumn season on 2008 .

Thirteen locally raised inbred lines were used in the study to calculate phenotypic coefficient of variability , genotypic variability, broad sense heritability, correlation and path analysis , the result showed that leaf area had significant genotypic and phenotypic association with ear length, number of kernels per ear and plant yield and also was found that genotypic and phenotypic coefficient had highly significant for plant yield, ear height and leaf area, while the traits (days to 50% silking, plant height, leaf area, and number of kernels per ear) had comparatively higher broad sense heritability in both season.

The number of kernels/ ear and leaf area direct influence on yield and indirectly affected the ear length , this traits could be utilize for kernel yield improvement.

The results of this study can be used of promising inbred lines in a program to produce the hybrid from locally inbred line.
