Abstract

Four diploid som genotypes viz., PB003, PB004, PB005, and PB006 along with four polyploid counterparts viz., PB009, PB010, PB011, and PB012 were evaluated through rearing of Muga silkworm from brushing till spinning during spring and autumn seasons under the agro-climatic conditions of Jorhat, Assam. Observations on leaf yield per plant, parameters for rearing performances and biochemical constituents such as crude protein, crude fiber, total carbohydrate, reducing sugar, total soluble sugar and moisture content were made. The results revealed that tetraploid som genotype namely PB012 is comparatively superior than other genotypes.
