Evaluation of different castor genotypes based on rearing performance of ERI silkworm, Samia cynthia ricini in Telangana State

Author(s): D Prasanna, Dr. GY Bhargavi
Abstract: ERI culture has been proven beneficial and gainful employment to the castor farmers, as 30% of defoliation will not affect the seed yield. Seeds of four high oil yielding castor hybrids / varieties viz. DCS-9, 48-1, DCH-519, DCH-177 along with local castor are collected from Directorate of Oil Seeds Research, Hyderabad to study the performance of ERI silkworm. Leaves of the five castor genotypes were fed to the ERI silkworm and studied the performance of ERI silkworm viz. larval traits, cocoon traits, grainage traits. The larval, pupa, and adult characteristics were found better in normal temperature and larval development of ERI silkworm during winter was prolonged than rainy season. This study reveals that of the five castors genotypes DCH-519 cultivation would be more beneficial to the castor farmer for ERI culture as it yields more after local castor variety.
