Selection and breeding unit: Shaanxi sericulture Research Institute.

Approval: approved by Shaanxi Provincial crop Variety approval Committee in 1987 and recognized by the National crop Variety approval Committee in 1994.

Variety registration number: GSIlop4-1994.

Variety source: (122x795) x (226x796).

Characteristics: high yield, high silk yield, middle line single-limited four-element hybrid, high reproduction coefficient, large silkworm body, large mulberry consumption at 5 years old, large cocoon shape, high cocoon yield and high output value. The average cleanliness is 96 points, the size of cocoon silk is 3.00D, the relaxation rate is 75%, the length of silk is 871.8 meters, and the cocoon shell rate is 25.28%.

Main points of feeding: the more mature seeds should pay attention to the adjustment of the starting point, and it is appropriate to protect the embryos outside the reservoir for 2 days after coming out of the reservoir, and then heat up to promote breeding and do a good job of dark protection to make the embryos develop neatly. It is suitable for mulberry to be ripe and tender for pushing silkworm. 5-year-old 3Mel 7 days should pay special attention to the full food of good mulberry. In the mature silkworm period, the amount of mulberry is still very large, so it is not suitable to suddenly reduce the amount of mulberry.

Suitable scope: trial cultivation in Northwest China.
