To determine-inter relationship between growth and yield at-tributing traits and their relation ship with yield in potato

Genotypic correlation coefficients for most of the traits revealed higher value to their Corresponding phenotypic correlation coefficient values indicating the inherent correlation among the traits. Tuber weight exhibited significantly positive correlation with tuber yield. Whereas, quality traits except ascorbic acid like protein content, specific gravity of tubers, dry matter content, total soluble solids, vitamin A, nitrogen content, phosphorus content and potassium content in tuber showed negative correlation with tuber yield indicated the yield and quality cannot be improved simultaneously rather independent selection for both will be beneficial. Similarly, number of tubers per plant and tuber weight has revealed negative correlation indicated that these two components could not be brought together in population therefore; independent selection should be practiced for these traits.
