新型叶用芥菜hau细胞质雄性不育杂种组合的加工模式

Processing pattern of a novel leaf mustard hybrid with hau cytoplasmic male sterility

以新型叶用芥菜细胞质雄性不育hau CMS所获的杂种为主要研究对象,选育获得1个叶用芥菜强优势组合（0912A×X2）,在已经明确杂种优势的基础上,通过正交设计试验研究杂交组合（0912A×X2）腌制加工过程中安全标准的硝酸盐和亚硝酸盐的最优处理模式。结果表明：腌制前期（0~15 d）,低含量硝酸盐的优化组合是腌制温度为30℃,亚硫酸钠添加量为75 mg/kg,食盐质量分数为3%,Vc添加量为0.02 g/kg;低含量的亚硝酸盐优化组合模式为腌制温度为10.7℃,亚硫酸钠添加量为50 mg/kg,食盐质量分数为1%,Vc添加量为0.01 g/kg;腌制后期（16~31 d）低含量硝酸盐的优化组合是腌制温度为25℃,亚硫酸钠添加量为0 mg/kg,食盐质量分数为1%,Vc添加量为0.03 g/kg;低含量的亚硝酸盐优化组合是腌制温度为10.7℃,亚硫酸钠添加量为50mg/kg,食盐质量分数为1%,Vc添加量为0.01 g/kg。利用新型芥菜细胞质雄性不育源选育而成的叶用芥菜杂交组合不仅杂种优势明显,而且腌制加工品质与对照没有明显差异。

A novel leaf mustard hybrid with hau cytoplasmic male sterility was used to breed a leaf mustard cross with strong heterosis （0912A×X2）.The basis of heterosis was studied.The safety stand- ards of nitrate and nitrite in the pickled process of 0912A× X2 were investigated.Results of orthogonal experimental design showed that nitrate content and nitrite content of 0912A×X2 was in the lowest level of optimization marinated process mode.Results of early marinated （ 0-15 d ） showed that the optimal combination of low level of nitrate was under the condition at 30 ℃ of pickled temperature, 75 mg/kg of sodium sulfite dosage,3% salt mass fraction,0.02 g/kg of Vc dosage.Optimized low level of nitrite was at 10.7 ℃ of pickled temperature, 50 mg/kg of sodium sulfite dosage, 1 % salt mass fraction,0.01 g/kg of Vc dosage.Optimal low level of nitrates of late pickled （ 16-31 d ） was at 25 ℃ of pickled temperature, 0.0 mg/kg of sodium sulfite dosage, 1 % salt mass fraction,0.03 g/kg of Vc dosage.Optimized combina- tion of low level of nitrite was at 10.7 ℃ of pickled temperature,50.0 mg/kg of sodium sulfite dosage, 1% salt mass fraction,0.01 g/kg of Vc dosage.It is indicated that the use of new mustard leaf mustard hybrid bred with cytoplasmic male sterility has Obvious heterosis and pickled processing quality. It will provide a theoretical basis for developing sources of material and processing leaf mustard hybrids in the future.
