家蚕品种性状综合评判方法研究

Research on Judgement Methods for Comprehensive Characters of Silkworm Varieties

为了正确选择适合生产上推广应用的家蚕新品种,以4龄万蚕产茧量、对4龄蚕健蛹率、解舒丝长、鲜茧出丝率、纤度均方差作为评价指标,分别采用标准化值代数和指数评判法、排队记分评判法、模糊综合评判法,并结合专家经验分配指标权重系数,对7对家蚕品种的综合性状进行了评判比较。结果表明,标准化值代数和指数评判法、模糊综合评判法适宜用于家蚕品种综合性状的评判,尤其是标准化值代数和指数评判法简单而实用。

Cocoon crop per 10000 fourth-instar silkworms, healthy pupa rate of fourth instar silkworms, length of nonbroken cocoon filament, raw silk percentage of fresh cocoons, and size mean square were used as five synthetic judgement indexes, and index weighting coefficient assigned by experience of experts. Seven comprehensive characters of silkworm varieties were judged and compared by algebra sum index of standard value method, lining scoring method, and fuzzy synthetic judgement method. The results demonstrated that algebra sum index of standard value as well as fuzzy synthetic judgement method are suitable for judgement of comprehensive characters of silkworm varieties, and algebra sum index of standard value is especially simple and practical.
