Influence of various mulberry genotypes on growth and yield components of seed crop pure Mysore race Multivoltine silkworm (Bombyx mori L.)

Abstract

Nutritional status of the mulberry leaves is very important and largely affects the performance of Bombyx Mori. Therefore, the experiment, conducted at P3/P2 Basic seed farm Nagenahally, comes under NSSO, CSB, Bangalore during 2016-17 to study the Influence of mulberry genotypes on growth and yield components of Pure Mysore race Multivoltine Silkworm. The experimental results revealed significantly lower larval duration (27.35 days) and highest weight of 10 larvae (26.37 g), yield per 100 dfls (39675 and 45.24 kg respectively), number of cocoons per kg (871), single cocoon weight (1.147), single shell weight (0.175 g), SR percentage (15.23%) and pupation percentage (96.79%) recorded with the mulberry genotype Victory-1 compared to Genotypes S36 and Kanva-2 (M-5).
