Effects of fertilizer application on stability of yield and yield components of sweet potato clones [Philippines]

Fourteen sweet potato clones were grown in fertilized and unfertilized tests at four locations during two years. Significant effects of genotype environment interaction on yield components of sweet potato were found. Yields were generally higher in fertilized tests. Number of roots was higher in fer...

Summary:Fourteen sweet potato clones were grown in fertilized and unfertilized tests at four locations during two years. Significant effects of genotype environment interaction on yield components of sweet potato were found. Yields were generally higher in fertilized tests. Number of roots was higher in fertilized tests for most grades except for canners and total number of roots. Rank correlations of stability clones in fertilized and unfertilized tests were low for all traits measured. Implications of the results in testing and selection of sweet potato are discussed.
