Abstract
The under consideration research studies, comprising 28 entries, were con-ducted at University of Agriculture, Faisalabad. The primary objective was to find out relationship between yield, yield components and oil content and ultimately the development of new genotypes with more yield and oil content. The correlation coefficient values for all genotypes were greater than that of the phenotypic. The grain yield was positively and highly significantly correlated with other characters except oil content. Number of kernel rows per ear, number of kernels per row and 100-grain weight showed highly significant and positive correlation between each other. The highest correlation co-efficient value "r" (0.91) existed between yield and 100-grain weight. The number of ears per row, number of kernel rows per ear, number of kernels per row, 100-grain weight and grain yield showed positive and highly significant genetic correlations but were non-significant for phenotypic correlations.
