| Abstract: | The new tussah variety Jiqing is hybridized on the basis of “Xuanda 2”by divisional feeding ,systematic separation and directive breeding .In the meantime ,other economic parameters were taken into consideration to breed the new variety which went through 9 years 18 generations .The selective breeding results are as follows：the whole cocoon weight is 13 .04g ;the weight of 1000 cocoon is 12 .36kg ,larva-pupa rate being 92 .91% .The output of pure breeding has increased by over 5% compared with Xuanda 2 and Jizuo88-2 .Hybrid with Jizha 88-2 and Xuanda 2 ,the output improved by 16 .7% ~22 .5% . |
