Biometrical analysis of pure races and crosses of silkworm raised in Umbria


, : Biometrical analysis of pure races and crosses of silkworm raised in Umbria. Riv. Biol, 22: 402-426

WITH a view to supplying the silkworm industry with data for the selection of the most suitable races under conditions prevailing in Umbria, the author has taken measurements of 17 characters of economic value, e.g. length, width, and volume of the cocoon, variability, rearing losses, weight of fresh cocoons produced per oz. of eggs, in 6 pure races and 9 crosses. The results are summarised in tables and graphically in profiles.
