The goal of many hybridizers is to create a toothed nepenthes that will grow warm. Most of the dagger type peristome species (N. hamata, edwardsiana ,villosa, etc.) are from cooler regions. One must first understand the reasoning for these "dagger" teeth. These exaggerated teeth are measures a plant takes to ensure that every prey that chances the lid are subject to falling into the mouth of the pitcher. This is not a problem for many lowland species which have surplus of insects and a higher chance of falling in, even if by chance alone.
Line breeding a species is a way to get back some of the traits that are recessive to show up in different seedlings. For example if we wanted to see more N. hamata from breeding, we would cross N. Predator (truncata x hamata) x hamata
Then cross back the above back to Predator, then recross the result with N. hamata, and then back to Predator. Using different clones of each would make a stronger more vigorous plant.
