| Abstract: | Eight half-sib families and thirty two full-sib families were obtained by a nested design of each male mating with four females. Heritability for shell length and shell height was 0.521±0.104 and 0.307±0.097 on day 1, 0.307±0.074 and 0.311±0.075 on day 10, 0.336±0.079 and 0.314±0.075 on day 20, and 0.318±0.081 and 0.280±0.075 on day 40, 0.383±0.091 and 0.423±0.097 on day 60. Heritability for production traits including shell length, shell height, shell width, and total weight at harvest on day 500 was 0.375±0.096, 0.358±0.094, 0.513±0.116, 0.420±0.103, respectively. Compared with other shellfish, heritability for production traits including shell length, shell height, shell width, and total weight of Patinopecten yessoensis Jay was of medium size. |
