| Özet |
| The aim of this study was to investigate the effects on some genetic parameters of different selection methods for Body Weight (BW) in Japanese quail. For this aim, line M55 was subjected to individual selection for 5 weeks BW while a reciprocal recurrent selection method was applied to lines R33 and S55. Selection lasted 2 generations. In individual lines, the percentage deviation of body weight was an average of 1.41, 1.73 and 2.19% in the 1 st generation males, females and mixed sex, respectively. These parameters reached 5.57, 7.44 and 6.29% in the 2nd generation. In the reciprocal recurrent selection, heterosis of BW in the crossbred birds occurred in the positive direction and was 3.22 and 1.95% for R3S5 and S5R3, respectively in the 1 st generation. In the 2nd generation, heterosis was calculated as 6.50 and 7.31% in R3S5and S5R3, respectively, higher than the 1 st generation. At the end of the 2 generations, R3S5 had higher heterosis than S5R3 BW increase was similar in the 2 selection methods. Hentability of BW in the individual lines was 0.27 and 0.73 in the 1st and 2nd generation, respectively. In the reciprocal selection, heritability of BW was estimated as 0.37 and 0.19 in the 1 st generation and 0.17 and 0.27 in the 2nd generation for R3S5 and S5R3, respectively. As a result, at the end of the 2 generations of selection, an improvement in BW increase was obtained in both selection methods. If selection is continued in these lines, this may be important especially with regards BW. © Medwell Journals, 2009. |
