Mulberry seedling varieties for silkworm breeding

Lu mulberry is a major variant of mulberry and is the main cultivated variety in my country's silkworm areas. The characteristics of Lu mulberry are that its leaves are large, up to 30 cm long, and thick and juicy, making it a rare good feed for silkworm breeding. Lu mulberry likes light and has strong adaptability to climate and soil. It is cold-resistant and can withstand low temperatures of -40°C. It is drought-resistant and not resistant to water and humidity. It can also grow in warm and humid environments. It likes deep, loose and fertile soil and can withstand mild salinity (0.2%). It is wind-resistant and resistant to toxic gases. It has a well-developed root system, grows fast, has strong germination ability, is resistant to pruning, and has a long lifespan, which can generally reach hundreds of years, and some can reach thousands of years.

4. How many varieties of mulberry trees are there? Are they all suitable for feeding silkworms?

Do you want to raise silkworms? The best mulberry tree for raising silkworms is: Alsophila mulberry variety has significantly higher cocoon formation rate and pupation rate for silkworms in the process of raising silkworms than other varieties. In the comparison of cocoon layer rate of silkworms, Morus altissima has the highest rate, followed by Alsophila mulberry, and the lowest is Autumn Rain, with cocoon layer rates of 18.82%, 16.54% and 14.90% respectively. There is not much difference in the survival rate of silkworms among the four varieties of mulberry trees throughout the whole age process.

The results of silkworm breeding with Alsophila chinensis and Morus altissima are quite remarkable, while the results of Mulberry chinensis and Morus altissima are relatively poor. Considering the silkworm breeding results and climatic conditions, the planting of Alsophila chinensis and Morus altissima should be further promoted on a large scale.
