In the valley of Apatzingán Michoacán, Mexico, the papaya (Carica papaya L.) Maradol Roja is cultivated, however, producers face a latent risk due to having a mono varietal production in relation to the health of the crop and the commercialization in a complex market. Given this, the objective of this research was to agronomically evaluate the development and fruiting of three papaya genotypes in the Ejido El Platanal, municipality of Tumbiscatio Michoacán, Mexico to determine their adaptability as a production alternative. The variables evaluated were: plant height, stem diameter, fruits per plant, elongated hermaphrodite fruits, pentandry fruits, height of the first fruit and leaves per plant. The experimental design used was in randomized blocks, three repetitions per block (one per genotype) and 20 plants per block with three rows. Comparisons between means were made with the Tukey test (p < 0.05). The results indicated that Siluet presented plants with more than 3 m in height, Maradol Roja 2.45 m and Amarela 2.32 m. The total number of fruits per plant differed statistically between the genotypes showing for Siluet 56.93, Maradol Roja 40.82 and Amarela 34.86. The height of the first fruit for Maradol Roja and Amarela were 0.86 and 0.84 m, respectively, which were statistically similar. It is concluded that Maradol Roja, Amarela and Siluet proved to have good potential for adaptability to this region and they constitute alternative materials to the traditional Maradol Roja variety.
