| Abstract: | The statistical data of the performance of 83 races of silkworm (Bombyx mori L.) germplasm resources in China, representing different geographical systems, from 1956 to 1996 were used to study the developing trend of their major characters and draw the graphs demonstrating their variation. The results showed that in the span of 40 years larva-pupa rate, larval survival rate and the rate of dead silkworm larvae in cocoon experienced considerable variation, variation in the performance of cocoon weight and cocoon shell weight was small and the performance in cocoon shell percentage remained stable. |
