摘　　要：永康市全年饲养家蚕天然彩色茧新品种“金秋×初日”,为了解全国现有彩色茧蚕品种在永康的适应性及品种特性,为今后的进一步发展提供品种储备和技术支撑,2019年晚秋对全国比较稳定的天然彩色茧新品种“苏彩2号”、“苏彩3号”、“M日”、“M中”、“广东彩茧”等与目前推广的品种“初日×金秋”进行对比试养,结果发现“金秋×初日”的体质强健性、蚕茧产量和茧丝质量都比较全面,是一对比较好彩色茧蚕品种;“广东彩茧”虽然强健性与“金秋×初日”相当,但蚕茧茧形小,产量低,不适宜在永康市推广;“苏彩3号”虽然茧层率、出丝率等都比“金秋×初日”高,但强健性明显差,在春季饲养条件比较好地区可以考虑,但夏秋季及规模化比较大,饲养比较粗放的条件下应慎重采用;其他几个品种实用性状都比较平衡,但综合性状都没有超过“金秋×初日”,在蚕种布局上可考虑具体情况合理使用。The new silkworm variety“Jinqiu×Churi”with natural color cocoon has been raised in Yongkang City throughout the year.To understand the adaptability and variety characteristics of the existing color cocoon silkworm varieties in Yongkang and provide variety reserve and technical support for further development in the future,the new stable natural color cocoon varieties“sucai 2”,“sucai 3”,“M Ri”,“M Zhong”and“Guangdong Caijian”were introduced for trial rearing in Yongkang rural areas in late autumn of 2019.The results showed that“Jinqiu×Churi”was a better hybrid with natural color cocoon because of its comprehensive physical fitness,cocoon yield and cocoon silk quality;“Guangdong Caijian”was not suitable to be popularized in Yongkang city because of its small cocoon shape and low yield,although its physical fitness was equivalent to“Jinqiu×Churi”.The cocoon shell rate and silk percentage of“Sucai 3”were higher than those of“Jinqiu×Churi”,however its robustness is significantly poor.It could be used in silkworm rearing areas with better rearing facilities and techniques in spring season,and it should be used cautiously in summer and autumn rearing season,large-scale or extensive feeding conditions.The practical characters of other varieties are relatively balanced,but the comprehensive characters are no better than that of“Jinqiu×Churi”,could be considered for reasonable distribution according to practical condition.
