• Genotypic correlation
• co-heritability
• heritability
• genetic expression

Selection and evaluation of nineteen potato (Solanum tuberosum L.) genotypes for yield and yield components by calculating genotypic, phenotypic correlation coefficient, heritability and co-heritability was done at Potato Research Sub-Station Muree. The positive genotypic correlation coefficient was observed for different potato grades, number of eyes/tuber and plant height with yield. The amount of co-heritability and broad sense heritability was maximum for traits, plant height, <35 mm potato grade and 35-55 mm potato grade indicated preponderance of strong genetic expression. Therefore, there was a potential for the concurrent genetic improvement of these traits through selection and breeding in the plant material used in present study.
