Two horticultural crops, the ornamental liriopogon and the sweetpotato [Ipomoea batatas (L.)
Lam.], were analyzed for morphological, quantitative and molecular marker variation using
Amplified Fragment Length Polymorphism (AFLP) and various multivariate statistical
techniques. Ornamental cultivars in genera Liriope and Ophiopogon were analyzed for
relatedness using AFLP marker data and statistical clustering methods. Marker data did not
substantiate the separation of these two genera. Greater than 95 % of the total genetic variability present was attributed to within group variation
