| Abstract: | The new mulberry variety chuan 799 was bred through radiation and hybridization. It was flourishing, the tree type was compact, the branch was thick and strong and erect, the leaf was easily plucked and harden late in autumn. The yield of the mulberry leaf was 23272.95kg per hm2 increased by 11.64% compared with the standard variety, He Yebai. The yield of cocoon and cocoon shell weight of 10 thousand larvae increased by 6.84% and 7.88%, the yield of cocoon of 50kg mulberry leaf at fifth instar increased by 9.45%, the yield of cocoon and cocoon shell weight per 667m2 of mulberry field increased by 16.18% and 17.83% respectively compared with He Yebai, It has been approved by Sichuan Grop Variety Evaluation Commission. |
