Identification of some Valuable Genotypes Based on Correlations between Morpho-productive Elements

Abstract

Every year, breeders create a small number of new varieties, which are cultivated, depending on the
needs of each country and the existing environmental conditions. Plant genetic resources are
represented by any type of reproductive or vegetative propagation of cultivated or newly created
varieties, being used by farmers over time for their own needs and for animal feed. The use of an initial
material with great variability, knowledge of the traits, the correct choice of parents, the use of the best
breeding methods and carrying out a scientific selection, are primary factors in obtaining new,
productive, and superior quality genotypes. A number of 185 genotypes were chosen from the spring
barley germplasm collection of ARDS (Agricultural Research and Development Station) Turda, for the
biometry. Part of the considerations underlying the choice of this material were the appreciation of
some morphological and production traits, of the lines created at Turda and of the older varieties in
relation to the new creations. The main agronomic traits of the production that were analyzed are
represented by: TKW (thousand kernel weight) ear length, number of grains/ear and grains
weight/ear. Experimental data processing was carried out with the ANOVA program.
