四川省桑树品种区试参试品种产量与质量性状分析

Analysis on Yield and Qualitative Characters of Mulberry Varieties that Joined in Regional Test in Sichuan Province

[目的]为四川省桑树品种的品质改良、品种选育及推广提供参考。[方法]以6个桑树品种川826、川7431、湖桑32号(CK)、桐乡青、川桑98-1、农桑14号为材料,采用对比试验研究各品种桑叶产量和质量的差异。[结果]桑树品种川7431的年均产叶量最高,为33 049.5 kg/hm2,其次为川桑98-1和川826,年均产叶量分别为31 050.03、0 975.0 kg/hm2,CK年均产叶量最低(22 890.0 kg/hm2);桐乡青的每50 kg桑叶产茧量最高,为190.575 kg,其次为川7431(198.550 kg),极显著高于其他桑树品种;川7431的年均产茧量最高,为2 505.825kg/hm2,极显著高于其他桑树品种。[结论]桑树品种川7431的桑叶产量较高、质量较优,适合在四川省内推广。

[Objective] The study was to provide the reference for quality improvement,variety breeding and generalization of mulberry variety.[Method]With 6 mulberry varieties of Chuan 826,Chuan 7431,Husang 32（CK）,Tongxiangqing,Chuansang 98-1,Nongsang 14 as tested materials,the contrast test was taken to study the differences of yield and quality of each mulberry variety.[Result] The annual average leaf yield of mulberry variety Chuan 7431 was the highest,being 33 049.5 kg/hm2,the following were those of Chuansang 98-1 and Chuan 826,being 31 050.0,30 975.0 kg/hm2 resp.,and that of CK was the lowest（22 890.0 kg/hm2）. The cocoon production with each 50 kg mulberry leaf of Tongxiangqing was the highest,being 190.575 kg,the following was that of Chuan 7431（198.550 kg）,being significantly higher than that of other mulberry varieties.The annual average cocoon production with mulberry leaf of Chuan 7431 was the highest,being 2 505.825 kg/hm2 and significantly higher than that of other mulberry varieties.[Conclusion] The mulberry variety Chuan 7431 with high yield and better quality of the leaf was suitable for generalization in Sichuan Province.
