The work was carried out in the environments of the teaching and research workshop on Amazonian medicinal crops, located in the environments of the Faculty of Agronomy of the UNAP, university city Zungarococha. The work corresponded to the explanatory level. The aim was to generate information on aspects of phenotypic variance components and heritability in the broad sense for, weight of 100 seeds, petal length, fruit length, seeds per fruit and number of stamens per flower studied in eight morphotypes of annatto (Bixa orellana L). The unrestrictedly random experimental design was used, three repetitions and eight experimental stimuli. An experimental unit was one tree and sampling unit was three trees/morphotype. In the weight of 100 seeds in grams, a greater contribution of the environmental component than the genetic effects were found. For petal length, fruit length, number of seeds ...
