Abstract

ABSTRACT The performance of the Bombyx mori L. double hybrid was evaluated on two mulberry mini clones of Morus spp. based on economic characters. The present investigation were reported that significant improvement in larval parameters were observed when fed with mini clonal mulberry leaves to silkworm. Treatment 60DAP-AC (V1) recorded increase in larval weight (3.15g), higher ERR (86.34%) and low larval mortality (13.46%) than check. Silk gland parameters like silk gland weight (648.61mg) and silk productivity (6.24cg/day) and cocoon parameters like shell ratio (21.99%), single cocoon weight (1.62g), shell weight (0.34g), pupal weight (1.28g) and cocoon yield/10000 larvae (20.56kg). The reeling parameters viz., filament length (1249.63m), filament weight (297.10mg), renditta (6.44kg) and denier (2.26) were also found to be superior in mini clones of V1 variety than check. In MR2 also maximum filament length (1235.53m), filament weight (295.71mg), renditta (6.94kg) and denier (2.22) were registered. All the mentioned factors were compared, and it was determined that 60DAP-AC (V1) is the best mulberry mini clone for rearing the mulberry silkworm.
