Wheat development in Indonesia still continues to this day are still focused on the highland. But the limitations of location-specific varieties and seasons as well as the strong winds that often occur in the highlands during the rainy season can cause lodging plant, an obstacle for the development of wheat in the country. Then carried out a study to analyze the character of lodging wheat plant in the Karo highlands, North Sumatra. The study was conducted on two location of the Karo highlands and three repetition with uses non-factorial randomized block design with using wheat plant genotype C (LAJ3302 / 2 * MO88) and the treatment used is nitrogen fertilizer ((N1 = 50 g/plot, N2 = 70 g/plot, N3 = 90 g/plot) and potassium fertilizer (K1 = 30 g/plot, K2 = 45 g/plot, K3 = 60 g/plot). This study aims to determine the genotypes of wheat which had fallen through the analysis of the character of lodging. Observation data were tested by analysis of variance and combined. Character of lodging was observed stem diameter, strong of stem, internode number and distance between internode. The results of the study and combined analysis of variance showed that stem diameter, strong of stem and distance between internode showed significant differences for each location. While the internode number not significantly different for each location.
