| Abstract: | A new mulberry variety with forward leaf maturity in spring, Nongsang-10,wasbred through breeding processess of hybridization,selection and regional test.Its annual and spring leaf yield per hectare was 17. 08% and 23. 11 % higher than the control varlety "Heyebai" respectively. The cocoon shell weight of 10000 silkworms reared with the bred mulberry was 2. 79% higher than the control. cocoon shells produced from per hectare mulberry was 24. 21 % higher than the control. The number of good eggs per 100 silkworms reared with Nongsang- 10 was similar to that reared with heyebai.It is highly resistant to yellow dwarf disease and black bacterial withering disease.It is also luxuriant and vigorous in growth, fairly resistant to drought, tolerant to poorsoil and with wide adaptability. |
