Description In anticipation of the effects of global warming on potato cultivation in both tropical and subtropical environments. Since 2004, efforts have turned to the development of a new group in Population B with improved adaptation to warm environments, resistance to late blight and virus, mid-season maturity (90 day growing period under short day length conditions), adaptation to mid elevations, low glycoalkaloids content, along with economically important traits such as high tuber yield, quality for table and industry, denominated LBHT (late blight, heat tolerance). In this context, in order to determine the narrow-sense heritability for yield components in the LBHT population, 32 clones were crossed at the Huancayo station in Peru in 2012 under greenhouse conditions using the North Carolina II mating design, The design was comprised of 4 sets, with 4 female and 4 male progenitors producing 16 full-sib progenies per set, for a total of 64 full-sib families. Tuber families of each progeny were generated in 2013 for evaluation under field conditions. And during 2014 –2015, the progenies were evaluated under field conditions, in three contrasting environments in Peru: San Ramon, La Molina, and Majes, where average temperatures at night were between 15.9 to 22.6ºC, and during the day fluctuated between 22.9 to 27.5ºC. The randomized complete block (RCB) design was used, with 4 sets and 3 replications of 50 genotypes per progeny.
