Seven multivoltine silkworm (B. mori) breeds (Pure Mysore (PM), Thai, P2D1, Hosa Mysore (HM), Nistari, Kolar Gold (Kg) and Kolega Jawan (KJ)) were crossed with 4 bivoltine breeds (Kalimpong-A (KA), NB4D2, NP18 and NP2) to identify superior hybrids both quantitatively and qualitatively. KJ crossed with bivoltine breeds produced the highest extent of progression to fourth ://   SILKWORM BREEDING AND GENETICS. Scientists: 1. Dr. N. Suresh Kumar, Scientist-D. 2. Dr. A.K Verma, Scientist-D. Mandate: Development of improved multivoltine and bivoltine breeds suitable for the Eastern and Northeastern zone. Identification of season specific hybrids (Multi x Multi, Multi x Bi, Bi x Bi) for Eastern and Northeastern However, the attempts to spread bivoltine silkworm breeds / hybrids throughout the sericulture belt of India resulted in extensive crop loss, especially in the hot and humid climatic conditions of Inbreeding of hybrids to stabilize silkworm breeds which bred true is well documented [12, 16–26]. Similarly, Kovolov [ 27 ] is of the opinion that improvement of silkworm races is possible by outbreeding with exotic races and improvement of cocoon quality by repeated backcrossing [ 28 ].
