Variability and Association of Tuber Yield and Related Traits in Potato (Solanum tuberosum L.).
2005
Baye Berihun and Ravishankat and Harjt-Singh
Thirty genotypes of potato were evaluated to estimate the nature and magnitude of variability and associations among tuber yield and related characteristics. Significant genotypic variability among the test genotypes were observed for plant height, stem number per plant, haulm dry weight, tuber number per plant, and average tuber weight. High heritability coupled with high genetic advance as a per cent of mean were recorded for haulm dry weight, plant height, average tuber weight, tuber protein content and stem number per plant. At genotypic level, average tuber weight and leaf area exerted high magnitude positive direct effects and also exhibited positive association with tuber yield per plant, suggesting their possible utilization to improve tuber yield per plant. Selection to improve tuber yield per plant could be feasible via leaf area and average tuber weight.
