Abstract
Establishing mulberry sericulture as a potential substitute for
boosting the agro-based economy holds high promise for the rural people in
Sujapur, Malda district of West Bengal, India. The present study was aimed to
assess the commercial rearing traits such as larval duration, larval weight,
cocoon weight, shell weight and larval size in addition to the common barometrical
data viz., ambient temperature
(24℃), relative humidity (49%) and photoperiod (11.20:12.40) of three mostly
reared breeds of silkworms in this area viz.,
nistari, SK6×SK7 and F1 (hybrid obtained by crossing nistari and SK6×SK7) in
the spring season (February to April, 2022). F1 breed showed significantly
greater variation in all parameters studied i.e., larval duration (24.67±0.88),
larval weight (33±3.21), cocoon weight (1.63±0.07), shell weight (0.31±0.0058) and
larval size (6.10±0.06). Pooled data with respect to different breeds were
analyzed statistically resulting in significant variations among the breeds for
all the parameters studied. This study documented the suitability of the F1
variety in Sujapur, Malda location for cultivation in Spring and the
potentiality for a hybrid program also. SK6×SK7 also could be a promising breed
but local unavailability and rearing problems hindered to flourish of the
breed.
