Abstract: | Some good mulberry varieties for leaf and sorosis were selected from a number of introduced varieties aiming at the introduction and breeding of the high-quality, high yield and strong resistance, among which the artificial triploid mulberry varieties, Fengtian 16 was excellent, of which the test results shown that: compared to the standard diploid control cultivar, Heyebai, the annum mulberry leaf yield in the unit acreage increased by 29.8%, silkworm cocoon shell weight per 10000 larvae increased 6.5% and cocoon production of 100 kg mulberry leaves increased 8.1%; compared with the another triploid mulberry variety both for leaf and fruit ,Da 10, the sorosis production in the unit area increased 9.5% and the leaf yield increased 24.7%. The variety Fengtian 16 showed typical mulberry triploid good characteristic with large leaf and fruit, vigorous growth, good quality and strong resistance, it was an excellent leaf-fruit integrated economic traits and high efficient mulberry variety. |
