Abstract

The existence of high genetic variability in the tropical germplasm popcorn, suggests the possibility of breeding for productivity and popping expansion. It is known that the cerrado area from Tocantins State presents favorable conditions for the exploration of this culture. The aim of this study to evaluate the genetic potential of families of 40 half-sib of popcorn in conditions of the cerrado area from Tocantins State. Thus, there were recombined two brands of popcorn, Produtos Paulista and Yoki. A randomized block design was used with two replications. At harvest time, the traits were measured, mass of grains per ear, grains yield and popping expansion. Those were observed significant genetic variability for all traits. The three traits showed gains with selection. Thus, it was found that the half-sib families of popcorn have genetic potential to be exploited in breeding programs for the conditions of the cerrado area from Tocantins State. However, the future studies need to be conducted to determine which breeding strategy should provide more significant results.
