Abstract

Studies were conducted in an environmental growth chamber to evaluate sixteen sweetpotato genotypes for dwarf characteristics that may be adaptable for advanced life support systems. Plants were grown from vine cuttings (15 cm long) of the selected genotypes and planted in 0.15 χ 0.15 χ 1.2m growth channels using a closed nutrient film technique system. Nutrients were supplied in a modified half strength Hoagland's solution with a 1:2.4 N:K ratio. Plants were grown for 120 days. Upon termination of the study, vine length, yield and biomass data were taken. Results showed significant differences among genotypes for all parameters measured. Storage root yield ranged from 47.25- 531.2g/plant. Generally, genotypes with semi-dwarf morphology showed the highest percentage root dry mass accumulation; however, foliage biomass was lowest for these genotypes. Four genotypes were identified based on height and canopy morphology as possessing semi-dwarf characteristics that will be suitable for advanced life support systems.
