Abstract
1. With a view to fix improved pure strains of silkwormBombyx mori Linn. suitable for the univoltine regions of India, two breeding plans were drawn up.
2. Out of eighty sublines isolated only five,viz., S18, S21, S36, S58 and S79 were finally selected on the basis of their peak performances.
These have been christened as Mandakini, Shivalika maid, Himalayan nymph, Doon Crescent and Yamuna respectively.
3. Field trials both at Dehra Dun and Kashmir under village conditions have given encouraging results.
