Abstract: As part of genetic diversity analysis between two varieties of Kuttanad ducks egg quality traits of Chara and Chemballi varieties of Kuttanad ducks under farm conditions was compared and assessed. The egg quality traits recorded at 40 weeks of age were satisfactory for both the groups. Standard procedures were performed to find out the various egg quality measurements. The mean value for shape index, albumen index, yolk index, and Haugh unit score of egg of Chara ducks was 77.22, 0.115, 0.408 and 91.07, respectively whereas the corresponding values of eggs of Chemballi ducks were 77.10, 0.112, 0.410 and 91.79, respectively. These differences in average values between the two varieties were statistically comparable between the two varieties. The shell thickness recorded for both eggs was 0.38 mm. The difference in mean per cent yield for shell, albumen and yolk was statistically significant (p<0.01) between the eggs of Chara and Chemballi ducks.
