Season, region and silkworm variety specific studies of silkworm Bombyxmori L. are of greater importance in identifying and understanding the adaptability of silkworm genotypes which largely influenced by climatic factors. The present experiment was made to analyze seasonal performance with a comparison shelf verses shoot rearing of bivoltine hybrid varieties viz. (single breed CSR2XCSR4, and double breed CSR6xCSR26XCSR2xCSR27) of Bombyx mori L. to check their adaptability and rearing performance in the climatic conditions of Khammam district. The result shows that the overall performance in three seasons’ i.e. rainy (Aug-Sep), winter (Nov-Dec) and summer (Feb-Mar), double breed shows better adaptation in Khammam district and in rearing Shoot rearing method shows better result in comparison to shelf method of rearing.
