Are papilla characteristics, which determine the market value of sea cucumber, hereditary?

本研究探讨了决定海参市场价值的乳突性状的遗传规律，为海参的选育提供依据。通过对亲本和F1代的比较，结果表明，乳突的数量受遗传因素的影响，利用微卫星DNA标记进行亲子鉴定是可行的。此外，在调查国内8个野生种群的乳突特征时，发现在北海道内浦湾发现的种群具有最多的乳突。在兵库县滨坂发现的海参的乳头长度最长。这些结果为选育具有上级乳突性状的海参提供了重要信息。

In this study, we examined the heredity of papilla characteristics, which determine the market value, for the selective breeding of sea cucumber. The parent and F1groups were compared, and the results suggested that the number of papilla was influenced by a genetic factor, and parent-child identification using microsatellite DNA markerswas possible. Moreover, when the papilla characteristics of domestic 8 wild populations were investigated, it was revealed that the populations of sea cucumbers found in the Uchiura Bay, Hokkaido, had the most number of papilla. The papilla length of the sea cucumbers found in Hamasaka, Hyogo, was the longest. These results yield important information for finding sea cucumbers with superior papilla characteristics foselective breeding.
