Breeding of A New Silkworm Variety with Higher Resistive Guican 9
摘要
Abstract
[ Objective ] The aim was to breed a new silkworm variety with higher resistive, to provide reference for deeply development of sericulture industry and promoting its economic benefit. [ Method ] 13 silkworm varieties with bivoltine and polyvoltine pedigree were bred by means of 5 times directional breeding under high temperature and humidity circumstances during 2 years and have combined lots of pairs of hybrid combinations and were selected Guican 9 by testing. [ Result] The results showed the cocoon yield per 10000 larvae and the shell yield per 1000 larvae were 4.23％ and 5.45％ higher than liangguang 2. The cocoon weight, the cocoon shell weight and the cocoon shell rate were orderly 4.54％, 5.60％ and 0.24％ higher than CK. The cocooning weight of newly hatched larvae was 5.71％ than CK;The value of newly hatched larvae was 2.97％ than CK. The cocoon filament length was 900 meters,3.75％ longer than CK. The length of non-broken cocoon filament was 759.7 meters, 4.43％ longer than CK. The reelability was 84.5％ , 0.4％ higher than CK. The dtex size and raw silk rate of fresh cocoon were orderly 84.5％ and 44.1％, 0.8％ and 0.9％ higher than CK. The raw silk rate of fresh cocoon was 0.1D lower than CK;The neatness and cleanness were the same as the CK. [ Conclusion] Guican 9 suits high temperature and humidity circumstances in south areas of Guizhou.关键词
