摘要
用纯系选育方法,以吐平面丝性状为重点,经过连续五个世代的强度选拔,育成ZAU2号(日系).其平面丝的吐丝率达95%以上。经过与中系品种的配合力测定和吐平面丝性状比较,选配了薪杭xZAU2号一代杂交种。经生产试用,表明该品种强健好养,张种产丝量高,且平面丝质量好。另外,一代杂交种试繁成绩表明,制种性能良好。
ZAU No. 2(Japanese strain)was bred by line-selection method through strict selection of the flat-way spinning character for five successive generations. After the test of combining ability by crossed with Chinese bred,the combination of Xinhang × ZAU No. 2 was selected out based the performance of flat-way spinning. Trial rearing showed that the variety of ZAU No. 2 not only have a high quality and quality of silk but the larva easy to rear. Moreover,it have rich amount of hybrid eggs production.
