Abstract A breeding selection program for improving inner shell color and growth was developed for Hyriopsis cumingii, to enhance purple pearl production. In freshwater pearl culture, adjusting culture water depth and mud substrate supply are routinely carried out to improve pearl quality. To improve selection decisions in different conditions, we estimated heritabilities and genotype by environment (G × E) interactions on inner shell color and growth traits in 1571 17-month-old animals from 8 half sib family of purple selective strain of H. cumingii reared in different water depths (WD1, 32 cm; WD2, 48 cm) and mud substrates (MS, mussel pond mud substrate; SS, shrimp pond mud substrate) were analyzed. With the same mud substrate, H. cumingii reared at WD1 showed increased performance in shell color and growth. Heritability estimates for growth traits (shell length, shell height, shell width, body weight and shell weight) were higher at WD1 and higher at WD2 for inner shell color parameters (L, a, band dE⁎) when rearing in MS, while showed opposite pattern in SS. At the same water depth, H. cumingii reared with MS showed better performance in shell color and growth traits. Heritability estimates for growth traits were higher in SS and higher in MS for inner shell color parameters when rearing at WD1, while showed opposite pattern at WD2. Heritability estimates for L, a and all growth traits were moderate and high (h2 > 0.15), while were low for b and dE⁎ (h2

通过环境相互作用对紫色淡水珍珠贻贝的内壳颜色和生长性状进行基因分型,在不同水深和泥质基质中饲养

摘要 为提高紫珠产量,开发了一种改善内壳颜色和生长的育种选择程序,用于改善三角帆蚌的内壳颜色和生长。在淡水珍珠养殖中,通常会调整养殖水深和补泥,以提高珍珠品质。为了改善不同条件下的选择决策,我们通过环境(G × E)相互作用对来自饲养的 8 个半同胞 H. cumingii 紫色选择性菌株的 1571 只 17 个月大动物的内壳颜色和生长性状的遗传力和基因型进行了估计对不同水深(WD1,32 cm;WD2,48 cm)和泥质基质(MS,贻贝池泥质基质;SS,虾池泥质基质)进行了分析。使用相同的泥质基质,在 WD1 饲养的 H. cumingii 在壳颜色和生长方面表现出更高的表现。在 MS 中饲养时,生长性状(壳长、壳高、壳宽、体重和壳重)的遗传力估计值在 WD1 较高,在 WD2 的内壳颜色参数(L、a、带 dE⁎)较高,而显示SS 中的相反模式。在相同的水深下,用 MS 饲养的瓜果在壳色和生长性状方面表现出更好的表现。在 WD1 饲养时,生长性状的遗传力估计值在 SS 中较高,MS 中的内壳颜色参数较高,而在 WD2 中则显示相反的模式。L、a 和所有生长性状的遗传力估计值中等和高 (h2 > 0.15),而 b 和 dE⁎ (h2 而在 SS 中表现出相反的模式。在相同的水深下,用 MS 饲养的瓜果在壳色和生长性状方面表现出更好的表现。在 WD1 饲养时,生长性状的遗传力估计值在 SS 中较高,MS 中的内壳颜色参数较高,而在 WD2 中则显示相反的模式。L、a 和所有生长性状的遗传力估计值中等和高 (h2 > 0.15),而 b 和 dE⁎ (h2 而在 SS 中表现出相反的模式。在相同的水深下,用 MS 饲养的瓜果在壳色和生长性状方面表现出更好的表现。在 WD1 饲养时,生长性状的遗传力估计值在 SS 中更高,MS 中的内壳颜色参数更高,而在 WD2 时显示出相反的模式。L、a 和所有生长性状的遗传力估计值中等和高 (h2 > 0.15),而 b 和 dE⁎ (h2
