The study was conducted on 68-year-old Scots pine crops growing in the Voronezh Region (Stupino Field site). Samples from six climatic crops were collected for dendroclimatic analysis of the response of radial growth in pine trees of different origins, growing under uniform conditions, to a limiting factor-drought. The response of radial growth to droughts in 1992, 1995, 2010, and 2014 was studied using the methodology proposed by Lloret et al. (2011): three years before the drought, during the drought year, and for three years after the drought. It was found that, in most cases, drought does not occur suddenly; the resistance index (three years before the drought) decreases. There is no direct connection between the intensity of drought and the response of climatypes, however, in the years of the most severe droughts (1992, 2010), growth was reduced in 5 of 6 climatypes. The most significant negative response to drought was observed for the "Minsk" and "Vladimir" climatypes. The "Voronezh", "Kalach", "Kursk", and "Belgorod" climatypes showed no clear advantage when all three indices were considered.
