GENERATION OF BASELINE INFORMATION ON THE FITNESS OF HYBRID POPULATIONS WITH SPECIFIC RESISTANCE TRAITS DURING NATURALIZATION AFTER GENE FLOW FROM IMPROVED POTATO CULTIVARS TO THEIR NATIVE CULTIVARS AND WILD RELATIVES IN PERU
The project will address the contribution of specific (resistance) traits to the survival of hybrids between a hypothetical transgenic potato and native and / or wild relatives in the natural environment. A hypothetical transgenic hybrids will be simulated using modern potato cultivars, hybrids between these and native and wild relatives that are the most abundant and sexually compatible in production areas where hybrid and native / wild potatoes coexist. Different environments, following an east-west transect through the
Andes, will be included to quantify genotype by environment interaction effects. The specific traits considered are among the most important for potato productivity: late blight resistance (Phytophthora infestans), resistance to the Andean Potato weevils (Premnotrypes spp.), and tolerance to drought. The add-on to fitness contributed by the specific trait will derive from ecological studies focusing on sexual and asexual reproductive capacity, including rate of flowering, berry production, tuberization, earliness, among others.
