Abstract

In some combinations obtained by cyclic hybridization between mutant/recombinant lines and several winter wheat varieties, it was studied the participation of genotypic variance, environment and genotype-environment relationship for characters such as: main stem length, leaf area, number of spikelets/spike, number of grains/spike and weight of 1000 grains.

The prognostic indicators regarding the choice of forms according to the phenotype were determined winter wheat genotypes the participation of genotypic variance, environment and genotype-environment relationship was studied for characters such as: length of main stem, leaf area, indicating the value of the paternal forms able to contribute to the improvement of each studied character. The genotype-environment relationship can be appreciated as a prognostic indicator when establishing limits for the use of agro-technical factors in order to increase production.
