      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.},
