Abstract

Realizing the need of bivoltine silk, as a substitute for the import, that suit to power looms and export oriented units in the country, the Government of India promoting bivoltine sericulture by implementing a number of programmes. Introduction of productive bivoltine single and double hybrids revolutionised the sericulture industry during 12th plan (2012-13 to 2016-17).  Towards this, systematic breed maintenance is the primary requisite to maintain the genetic compositions of the parents and combine well to express full potentiality in their hybrids. Thus, In the present study, hybrid vigour in terms of heterosis for different crossing pattern involving four oval (CSR2, CSR17, CSR27 and S8) and four dumb-bell (CSR4, CSR6, CSR16 and CSR26) type cocoons of bivoltine parental breeds was investigated considering important economic traits. All the parental breeds and their hybrids of different crossing pattern (single cross, foundation cross and double cross) were reared employing one way system of breed maintenance and standard rearing technique of bivoltine rearing, respectively at P4 Basic Seed Farm, Hassan. The analysed data indicates that the parental breeds were not only confirming the original breed characteristics but also expressed relative heterosis positively in their crosses for all the nine economic traits studied. Thus, we suppose that breed maintenance is mandatory not only to maintain the purity and stability of breeds but also to express their hybrid vigour in their crosses, which facilitate to exploit full potentiality of the hybrids in the field.
