Breeding new mulberry varieties by Artificial Triploid

The breeding of mulberry varieties is generally completed by traditional grafting technology, but the grafting technology is not only labor-intensive, but also high cost Today, the reporter learned from the sericulture Research Institute of Shandong Academy of Agricultural Sciences that the research group of the Institute has successfully selected a new cuttable mulberry variety Lu Zao No.1 with high quality and high yield by applying the artificial triploid breeding technology According to experts in the industry, cutting seedlings instead of grafting seedlings is an important innovation in mulberry seedling raising in China, which significantly improves the efficiency of seedling raising and further reduces the cost of seedling raising China is the largest producer and trading country of cocoon silk in the world, and the output of cocoon silk ranks the first in the world In some areas of China, sericulture has become a pillar industry in local rural areas Mulberry leaves are the feedstuff of silkworm The quality of mulberry leaves has a great influence on silkworm's physical fitness, cocoon quality, Germplasm and even silk quality and yield The new cuttable mulberry variety Lu Zao No 1 has large leaf thickness, good leaf quality and high leaf yield It not only has strong resistance to mulberry yellow dwarf disease, but also has strong cold resistance and strong rooting ability It is especially suitable for hardwood cutting and is easy to cultivate The technical personnel of the sericulture Research Institute of Shandong Academy of Agricultural Sciences also pioneered the technology of ventilating and catalyzing roots under the sun hotbed of mulberry, which greatly improved the survival rate of cuttage seedlings According to Chen Chuanjie, the breeder of the new mulberry variety, Lu Zhan 1, the economic benefit is very significant The variety has been popularized for 700 hectares, with an economic benefit of 12.13 million yuan In the process of breeding and promotion of new varieties, a number of specialized seedling raising households also emerged, which effectively promoted the local seedling propagation and seedling raising ability Because the cost of breeding is relatively low, it stimulates the enthusiasm of sericulture households in large area To improve the quality of cocoon, silk and silk by improving the leaf quality of mulberry varieties has always been the goal of mulberry breeders at home and abroad The emergence of new cuttable mulberry varieties will play an active role in the sustainable development of China's silk industry and the improvement of its international competitiveness On November 17, Shandong Academy of Agricultural Sciences sericulture research institute undertook the project of "high quality and high yield cuttable mulberry new variety Lu Zhan No.1 breeding" which passed the appraisal Experts believe that the project research has reached the international advanced level of similar research, and has important promotion and application value.
