摘要
通过１９９３～１９９６年４年试验调查结果：试验调查的原蚕具有龄期经过短、体质强健、结茧率和虫蛹率高、产下卵量多、克蚁制种和５０ｋｇ桑叶制种成绩优等特性。与贵州省现行用种相比，试验原蚕的四龄蚕结茧率和虫蛹率平均值分别提高２．０１％和２．９０％，羽化率提高２．４３％，平均单蛾产下卵提高７．２５％，克蚁制种和５０ｋｇ桑叶制种量分别提高２９．４１％和２４．７３％。
The results from four years' experiment showed that the experimental original silkworms were of a short age period, strong constitution, higher cocooning and pupation rate, more eggs and higher propagation quantity of newly hatched silkworm per gram or per 50kg mulberry leaf. Compared with the popular silkworm varieties in Guizhou, the cocooning rate, pupation rate, eclosion rate, egg number per moth, the propagation quantity of newly hatched silkworm per gram and per 50kg mulberry leaf increased by 2.01%, 2.90%, 2.43%, 7.25%, 29.41%, and 24.73% respectively.
