L. Škarková, H. Vlachopoulou, K. Haleal
Summary
Problems of the genotype-environment interactions
were studied on the model of a population of three sheep breeds, kept in four
halls with different feeding and housing systems. The influence of the environmental
effects and the subsequent genotype -environment interactions was studied in
the reproductive traits of the ewes, the growth capacity of the lambs and the
production characteristics of the sheep, expressed by live weight and greasy
wool output- The least square method was used for the calculation.
Key words:
external and internal environmental effects, genotype,
interaction, least square method
