基　　金："十五"四川省农作物育种攻关项目(2001-12-02-02)

摘　　要：经多年观察比较,新桑品种“川826”表现出遗传性状稳定、优质、高产、抗性较好等优点,2000年正式列为“十五”省农作物育种攻关项目“优质、高产桑、蚕新品种选育”中桑主攻品种,并进一步进行区域性比较试验。经过2002年至2005年在四川省乐山、三台、蚕研所等三点的比较试验和在四川篷安生产示范点的示范繁殖,“川826”与对照品种“湖32”相比,其产叶量高13.95%,万头产茧量高8.88%,万头产茧层量高8.8%,五龄担桑产茧量高13.51%,667 m2(亩)桑产茧量高28.2%,桑产茧层量高27.6%。特别是用“川826”桑叶养蚕后产卵制种成绩尤为突出,单蛾产卵量比对照高6.87%以上,单蛾正常卵粒数比对照高5.63%以上。2006年4月被四川省农作物品种审定委员会审定为合格品种。The new mulberry variety-Chuan 826 which have stably hereditary, high yielding, high quality and so on was bred by Sericultural Research lntitute of Sichuanis. In 2000, it became the key race of the ＂tenth five years＂ major item breeding high quality and high yielding mulberry and silkworm varieties. From 2002 to 2004, the comparative experiments were carried on in Leshan, Santai and the Sericultural Research Intitute of Sichuan Province, the reproductive test was performed in Pengan of Sichuan Province. Compared to ＂Husang 32＂, the test results show that the yield of mulberry leaves increased by 13.95 % , cocoon weight per 10 000 larvae increased by 8.88 % , cocoon shell weight per 10 000 larvae increased by 8.8 % , cocoon yield of 50 kg mulberry leaves for 5 instars increased by 13.51% , cocoon yield in 667 m^2 increased by 28.2 % , coccon shell weight in 667 m^2 increased by 27.6 %. Especially, raised by the mulberry leaves of Chuan 826, eggs of the signal moth increased by 6.87 % , normal eggs of the signal moth increased by 5.63 %.
