Abstract:

To understand interrelationships among different yield and yield attributing traits in potato (Solanum tuberosum L.) an experiment was conducted using twenty potato genotypes including 2 checks namely Khufri Pukhraj and Kufri Chipsona 1. The observations were recorded on eighteen traits. Correlation coefficient analysis revealed that total tuber yield plot-1 was showed highly and significantly positive correlated with specific gravity, number of shoots plant-1, dry matter content of shoots, unmarketable tuber weight plant-1 and starch content at genotypic level. However, it had exhibited highly significant positive association with number of branches plant-1 at genotypic and phenotypic level respectively. Thus direct selection for above traits will be effective and helpful in improving total tuber yield. Path coefficient analysis unveil that total tuber yield plot-1 was found high positive and direct effect for the traits plant emergence %, number of branches plant-1, number of shoots plant-1, dry matter content of shoots, tuber weight plant-1, marketable tuber weight plant-1, unmarketable tuber weight plant-1, harvest index and specific gravity. So these traits would be most suitable for direct selection and improvement of potato genotypes for tuber yield.
