چکیده

Genetic variability is a fundamental condition for the genetic gain in improvement programs (Ferreira et al. 1995). Regarding recurrent selection, it is expected that in the sequence of the consecutive cycles the mean values of the traits of interest increase in function of the concentration of favorable alleles, although without reduction in the genetic variability (Hallauer 1971). The high genetic variability in the base population associated with methods of genetic improvement that reduce the inbreeding effects is essential for the longevity

Genetic gains in the UENF-14 popcorn population with recurrent selection.

The popcorn breeding program of Universidade Estadual do Norte Fluminense Darcy Ribeiro aims to provide farmers a cultivar with desirable agronomic traits, particularly with respect to grain yield (GY) and popping expansion (PE). We evaluated full-sib families from the seventh cycle of recurrent selection and estimated the genetic progress with respect to GY and PE. Eight traits were evaluated ...

Improvement of a popcorn population using selection indexes from a fourth cycle of recurrent selection program carried out in two different environments.

We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The progenies were evaluated in a randomized block design with two replica...

Snap bean recommendation based on different methods of phenotypic stability.

In order to recommend the best strains of snap beans from the Universidade Estadual do Norte Fluminense (UENF) breeding program, different methods of analysis of phenotypic stability were adopted to evaluate the performance of 14 lines (F(9) and F(10)) of indeterminate growth habit, which were compared with 3 controls, namely, 2 commercial varieties (Feltrin and Top Seed Blue Line) and 1 ...
