[Proteolytic enzymes as markers of productivity and heterosis of silkworm].
A positive correlation between the activity level of cysteine proteinases in developing eggs of common silkworm moth (Bombyx mori L.), on the one hand, and a set of commercial characteristics, on the other, was found. This allows the determination of cysteine proteinase activities (pH optima of 3.0, 3.6, and 8.6) to be recommended as a biochemical test for an early prediction of potential productivity of silkworm breeds. A positive correlation between the activity level of acid cysteine proteinases in eggs of parental breeds and a set of commercial characteristics of their hybrids was detected, indicating a principal possibility of predicting the degree of heterosis.
