Abstract

Three varieties of mulberry namely 51, TRIO and Kosen were taken for this purpose during 1994–95. Among them Kosen showed better response regarding larval and cocoon traits than TR10 and S1 though the difference among these three varieties was not significant for all the traits studied so far. All the traits viz., larval weight, cocoon weight, shell weight, silk ratio, ERR in number and weight showed positive correlation with cocoon yieId and negative correlation with room temperature and relative humidity.
