Abstract

Abstract
More than %90 of natural silk in world is produced by means of mulberry silkworm (Bombyx mori L.). Therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. For this purpose, an experiment was conducted with five mulberry varieties (Kenmochi, Kairyonase, Ichinose, Shinichinose and Local varieties) during two seasons(spring and late autumn) in Iranian silkworm research center. After recording, obtained biological and economical characters, data (such as larval duration, larval nutrition duration, larval mortality, number of cocoon, best cocoon weight, best cocoon shell weight, shell cocoon percentage, etc.) were analyzed using a complete randomized design (CRD) model with factorial arrangement including ten treatments with three replications by means of IRRISTAT statistical software. The ANOVA results showed that type of mulberry varieties and rearing seasons have significant effects on silkworm yield (P
