Correlation and path coefficient analyses of tuber yield and yield components among potato (Solanum tuberosum L.) genotypes at Bekoji, Southeastern Ethiopia

The aim of the experiment was to determine correlations between tuber yield and components measure direct indirect effects on potato genotypes. conducted using eleven genotypes with one standard check variety (Belete) a local at Kulumsa Agricultural Research Center, Bekoji sub-station during 2020-2021. Data were collected for yield, dry matter content (%), plant height (cm), stem number, specific gravity, phenological parameters. Since two seasons had heterogeneous error variance, analysis carried out separately. In 2020, correlation indicated that positively significantly associated (0.608), marketable (0.997) content, number per plant, days maturity, while it negatively correlated emergence flowering genotypic level. Total maturity (0.640), (0.791), (0.977) While gravity phenotypic level; level in second season. Results path analyses tubers highest positive effect (+1.059) total followed by (+0.057) (+0.026) 2020 (0.7107), (0.2842), (0.0078), (0.1250) also 2021. addition, most significant positive. Significant tuber, they could be used as criteria improvement breeding programs. Int. J. Agril. Res. Innov. Tech. 12(2): 144-154, December 2022
