Potato is one of the most important food crops in terms of annual production and food security worldwide. The crop is affected by several types of biotic stresses, e.g. insects, viruses, fungus, nematodes and weeds, which are the prominent limiting factors for its production. The conventional breeding methods in potato have been associated with limitations; none of the present day commercial cultivar has built-in resistance against biotic stresses. There is strong need for the development of new resistant potato varieties to cope against biotic stresses using non-classical approaches in combination with classical methods. The scientific literature suggests the contribution of modern biotechnological techniques for the development of transgenic potato lines resistant against insects and diseases. The present comprehensive review describes different genetic engineering approaches for the development of transgenic potatoes resistant to insects, weeds, nematodes, fungus and viruses by fellow researchers worldwide. It also gives an insight into modern technologies, e.g. RNAi and CRISPR-Cas9, which have emerged recently and can be implemented in the development of biotic stress resistant potato cultivars.

Resistance test strains of transgenic potatoes transformed with RB gene to late blight (Phytophthora infestan) in KP Pasirsarongge, Cianjur.  Potato late blight caused by Phytophthora infestans (P. infestans) (Mönt.) de Barry continues to be one of the most important crop diseases of all time. Genetic engineering of potato using RB gene for resistant plant to this disease is the most effective and environmental friendly to prevent widespread of late blight. This research aims to perform resistance of transgenic potato lines containing RB gene to lateblight (P. infestans) in Pasirsarongge, Cianjur field trial station. The first generation of transgenic lines were planted on polybag containing soil:manures using randomized complete block design. Tested plant inoculation was done naturaly from inoculum source from border row (Granola) that has been planted at one month before. The symptom was observed at one month after planting and damage scoring was done every three days for five times. Twenty two transgenic lines of tested plant showed various resistance respond to late blight (P. infestans) attack. Three transgenic lines showed highly resistance to late blight (P. infestans) were lines 11, 24, and 25, one transgenic line has resistant level was line 6.
