The tussah silkworm landraces of excellent healthiness and greenish yellow silkworm blood and “Xuandayihao”with larger cocoons were selected as parent materials ,a new tussah silkworm variety “Gaoxinyihao” with high ratio of feed conversion and disease -resistance was successfully bred by means of hybrid innovation and systematic breeding tech-nology after 11 years and 22 generations .The NPV disease resistance capability of the new variety was 6 .6 times of“Xuandayihao”variety ,with 47 .9d whole larval duration ,the whole cocoon weight of 11 .36g and a cocoon shell weight of 1 .30g .The weight of 1000 cocoons was 11 .35 kg ;the survival ratio of larva -pupa was 97 .50% ;the ratio of cocoon weight conversion during fifth instars was 23 .00% ;the ratio of cocoon shell weight conversion during fifth instars was 2 . 64% ;the ratio of cocoon harvest to biginning rearing was 33 .92% ;the cocoon yield per moth was 118 .Compared with the control ,the new variety has a significant difference (P<0 .05) .
