华南地区家蚕资源品种的人工饲料摄食性调查

Ingestive Habit Investigation of Silkworm Race Resources to Artificial Diet in South China

对华南地区保存的167个家蚕资源品种和组配的19个杂交种进行人工饲料摄食性调查发现,摄食率高于91%的品种占调查品种的44%,表明华南地区选育适合人工饲料饲育的家蚕品种有丰富的基础材料。同品种不同蛾区家蚕对人工饲料的摄食性调查发现,摄食率高于97%的品种蛾区间差异不明显,摄食性遗传稳定;摄食率低于90%的品种蛾区间的差异较大,表明可有效选拔提高品系的人工饲料摄食性。

Through investigating 167 races and 19 hybrids, the ingestive rate of 44% races was above 91%, which showed that there were rich basic races for artificial diet breeding selection. Interbatch difference of same race with ingestive rate more than 97% were not significant, which showed that the ingestive habit heredity was stable. Ingestive habit difference was rather remarkable when the ingestive rate of the race was below 90%, which showed that it was possible to improve the ingestive behavior to artificial diet through further selection.
