Abstract. Identifi cation of the strongest families in purebreds is highly eff ective in the selection of silk curti silkworms. To demonstrate a high level of heterosis within a breed or in crosses, it is possible to create several expensive, valuable families and obtain new highly productive systems with high genetic potential in terms of cocoon weight and silkiness.

Аннотация. Выявление сильнейших семей у чистопородных высокоэффективно в селекции шелковой курти тутового шелкопряда. Для проявления высокого уровня гетерозиса внутри породы или в помесях можно создать несколько дорогостоящих, ценных семей и получить новые высокопродуктивные системы с высоким генетическим потенциалом по показателям массы кокона и шелковистости.
