Mulberry Varieties

Breeding is usually done through traditional grafting techniques, but grafting technology is not only laborious and laborious, but also has a high cost of raising seedlings.

Reporters learned from the sericultural Institute of Shandong Academy of agricultural sciences today that the tribe breeding technology of the research group has successfully selected high-quality and high yielding cuttings of mulberry, Lu Ting 1.

Industry experts say that cutting seedlings instead of grafting seedlings is an important innovation in mulberry breeding in China, which has significantly improved the efficiency of seedling raising and further reduced.

Grow seedlings

Cost.

China is the largest cocoon and silk producer and trading country in the world. Cocoon silk production ranks first in the world.

In some areas of China, sericulture has become a pillar industry in local rural areas.

Mulberry leaf is the feed of silkworm. Mulberry leaf quality has great influence on silkworm body's robustness and cocoon quality, germplasm, even silk quality and yield.

A new cuttage of mulberry new variety, Lu Ting No. 1, has thick leaves, excellent leaf quality and high leaf yield. It has not only strong ability to resist mulberry yellow dwarf disease but also strong cold resistance and strong root strength, especially suitable for hardwood cutting and easy cultivation.

The technical personnel of the sericultural Institute of Shandong Academy of Agricultural Sciences also pioneered the technology of ventilating and root pressing under mulberry solar hotbeds, which greatly improved the survival rate of cuttage seedlings.

According to Chen Chuanjie, a variety breeds, the economic benefits of cutting 1 new mulberry varieties are very significant.

The variety has been promoted to 700 hectares, with an economic benefit of 12 million 130 thousand yuan.

In the process of breeding and extension of new varieties, a number of seedling specialized households also came into being, which effectively promoted the local propagation and seedling raising ability.

Because the cost of raising seedlings is relatively low, it has stimulated the enthusiasm of sericulture households to raise silkworms in large areas.

Improving the quality of mulberry varieties leaves to improve the quality of cocoons, silk and silk has always been the goal of mulberry breeding workers at home and abroad.

The advent of new cuttings of mulberry trees will play a positive role in the sustainable development of China's silk industry and the competitiveness of the silk industry in the world.

。

In November 17th, the Sericultural Research Institute of Shandong Academy of Agricultural Sciences assumed the "high quality and high yield cuttings New Mulberry Variety Lu plug 1" breeding project through appraisal. Experts believe that the project has reached the international advanced level of similar research, and has important promotion and application value.
