Selection Indicators of Yield Components and Yield for Improvement of Local Sweet Potato under Water Stress

نویسندگان

چکیده

Genetic diversity is required for crop improvement against environmental stress. Astudy wasconducted to determine characters as selection indicators of water-stress tolerance, and yield components yield. The research method involved a one-factor experiment with 21 sweet potato clones, using Completely Randomized Block design three replicates. Water stress in this study mean that the bottom plants was submerged water at 2 3 months age. Determination conducted by estimating coefficients genetic phenotypic variations, heritabilities, advance correlation test result. number leaves, individual leaf area, area per plant, index, stem length, internode tubers (storage root), tuber weight yieldas tolerance. Selection consisted less small size, short stemsand branches, whereas were weight. became effective efficient when influenced greatly factors.

Combining ability of highland tropic adapted potato for tuber yield and yield components under drought

Recurrent drought and late blight disease are the major factors limiting potato productivity in the northwest Ethiopian highlands. Incorporating drought tolerance and late blight resistance in the same genotypes will enable the development of cultivars with high and stable yield potential under erratic rainfall conditions. The objectives of this study were to assess combining ability effects an...
