Abstract	Artificial breeding bypasses the effect of natural selection and, inevitably, subjects game birds to selection by breeding technology. For this reason, we evaluated whether different breeding technologies, carried out for six generations, were enough to differentiate two grey partridge lines. Two lines of grey partridges, obtained from the same population, were used: the animals of the line “broody” had been hatched directly by their own mothers for six generations; the animals of the line “incubator” had always been hatched in incubators from eggs laid by cage-reared grey partridges. Offspring from the two lines were reared under the same conditions and 2 years of production were monitored. Results showed that grey partridges of the “broody” line had a shorter and delayed laying period and, consequently, a lower egg production than the “incubator” line. In the first year of production, mean length of laying period 58 vs. 75 days, p<0.01; mean start of egg production through photostimulation: 61 vs. 42 days, p<0.01; mean number of eggs laid: 46 vs. 58, p<0.01. In the second year: mean length of laying period, 63 vs. 66 days, p<0.05; mean start of first egg production through photostimulation: 51 vs. 45 days, p<0.05; mean number of eggs laid: 45 vs. 56, p<0.01.
