菁松、皓月不同地域保育系比对试验初报

Conservation Constract of Jingsong and Haoyue in Different Regions

菁松×皓月从20世纪80年代初进入生产应用,实现了我国多丝量品种的第四次更新换代;持续30余年为全国生产上的主要多丝量品种,为我国茧丝绸行业的发展发挥了重要作用。为了提高菁松、皓月原种繁育性能,解决"菁松×皓月"在生产应用中的问题,经鲁、苏、浙三省蚕种主管部门协商,从2015年开始组织开展了山东、江苏、浙江生产上应用的菁松、皓月原原种的比对试验。通过2年试验表明,由于各地对品种的要求有所差异,在保种过程中有所侧重,不同地域(鲁系、苏系、浙系)菁松、皓月原原种的性状表现出各有所长。

The production and application of Jingsong × Haoyue began from 1980 s, which plays an important role for the development of the silk industry in China. To improve the breeding performance of parent eggs of F1 hybrid of Jingsong × Haoyue and solve the problems in production and application, the conservation constract of grand parent eggs of F1 hybrid of Jingsong × Haoyue in Shandong, Jiangsu and Zhejiang was carried out from 2015. The results showed that the requirements of varieties varied from the three different regions, and the characters of grand parent eggs of F1 hybrid of Jingsong × Haoyue in Shandong, Jiangsu and Zhejiang showed diffrent good points.
