Nineteen sweetpotato parents selected only for early blooming were reciprocally intercrossed in a modified diallel to generate a population suitable for quantitative genetic studies. In subsequent generation random intercrossing was effected by insects. Although no conscious selection was imposed on the population, selection for flowering was unaboidable. Morphological variability and phenotypic correlations of 32 and 39 characters were studied in Cycles 1 and 3. Very wide variability was recorded for all characters studied. Distributional shifts from Cycle 1 and 3 were noted predominately in flowering and in those characters most subject to selection in the history of the originating plants. Mos correlations could be explained on physiological bases, but thefollowing appear to be due to genetic linkage: high carotene and low root-flesh oxidation (.599**), leaf-vein and root-skin purpling (.311**), leaf-vein purpling and flowering (-.148**), and root-skin purpling and flowering (-.179**). The ranges, distributions and correlations obtained indicate that the population is suitable for quantitative genetic study with little bias expected from previous selection of parentalstocks or from the unavoidable selection for flowering imposed by the breeding procedure. Results are expected to have general application to sweetpotato investigations. |
