Abstract: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 correlations 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, <35mm potato grade and 35-55mm 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.
