Abstract: The twenty one F1 mulberry hybrids were developed using line x tester mating design using seven females and three male mulberry genotypes were planted in the field in RCBD design with three replications during the year 2019-20 at the Department of Sericulture UAS, GKVK, Bengaluru. The six best performing mulberry crosses along with check variety V1 were selected on the basis of combining ability studies with high sca effects which was found significant for leaf yield and growth parameters were selected and estimated for biochemical constituents of leaves and further bioassay studies of silkworm (Bombyxmori L.) was conducted. Results revealed that the hybrids, M. cathyana? C-776 recorded highest nitrogen content (3.70 %) and crude protein content (23.10 %), MI- 47 ? MI- 66 recorded highest potassium (1.71 %), MI-47 ? V1 recorded highest crude fibre (9.51 %) and ash content (9.79 %) when compared to check variety V1. Whereas, biochemical constituents viz., phosphorous (0.58 %), moisture content (69.65 %), chlorophyll (2.36 mg/g), carbohydrates (17.77 %) and phenol (3.52 %) were recorded highest in the check variety V1. Bioassay studies of silkworm revealed that rearing parameters were significantly more in the silkworms fed with the leaves of MI-47 ? V1 and M. cathyana? C-776 hybrid. MI-47 ? V1 recorded maximum cocoon weight, pupal weight, shell weight and silk productivity when compared to check variety V1. But none of the hybrids out yielded the check variety V1 for maximum larval weight, shell ratio, ERR and minimum larval duration.
