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

Abstract: The aim of the experiment was to determine the correlations between tuber yield and yield components and to measure the direct and indirect effects of yield components on tuber yield of potato genotypes. The experiment was conducted using eleven potato genotypes with one standard check variety (Belete) and a local check at Kulumsa Agricultural Research Center, Bekoji sub-station during 2020-2021. Data were collected for tuber yield, tuber dry matter content (%), plant height (cm), stem number, specific gravity… Show more

“…The data suggests that an increase in positively associated traits contributes to an increase in yield per plant. In line with this, Panigrahi et al [18], Patel et al [19], Shubha, and Singh [11 ], Lavanya et al [20], Singh et al [21], Gebreselassie and Ajema [22], Hunde et al [23], Nigussie et al [24], Sandilya et al [25], Tessema et al [26] and Tsagaye et al [27] also reported a significant correlation between tuber yield and several other traits, including tuber number, tuber weight, plant height, main stem per plant, average tuber weight, and tuber weight per plant. Consequently, improving tuber yield in potatoes is possible by employing an appropriate breeding strategy that selectively targets these positively correlated traits.…”
