摘要: 【目的】对应用中的甜菜成对保持系和不育系材料进行细胞质类型鉴定,为甜菜保持系和不育系的选育提供理论依据和技术指导。【方法】结合田间育性性状调查,利用开发出的VNTR特异引物TR1、TR2、TR3和TR4对40份甜菜试验材料进行分子鉴定,根据特异性条带区分细胞质类型。【结果】21份拟入选不育类型的材料中检测出符合Owen型的材料有N9849-17-1、N9865-103-C1、N9857-5-1-TH1-400、MS321-C27-1-80、MS331-N70、MS343-80、MS117-3-6-4-2、MS301-500、MS351-80、MS327-70-80、MS333-70-80、MS335-N70、2068B-2、MS151-1-16-301-400、MS317-1-8-301、MS313-506-600、MS320-7-605-1-84,其中MS329-N70、MS323-503-600分别为N1和N2型细胞质;19份拟入选可育型材料中检测出符合N1型细胞质的材料有960767-201TH-1、960764-1-11-1-1-400、OT322-C7-70-80、OT332-N70、OT352-80、OT328-70-80、BS301-13-9、OT352-80-1、OT342-80、OT152-1-6-301-400,符合N2型细胞质的材料有OT302-500,其中960766-1077-c1、OT344-80、OT118-4-5-4-4、OT324-501-600为Owen型细胞质类型;分子鉴定结果不纯的材料有6份(MS351-80-1、MS341-80、OT152-1-1-C301、OT330-N70、OT334-70-80、OT336-N70)。田间育性调查对应分子鉴定结果表明,960766-1077-c1、OT344-80、OT118-4-5-4-4和OT324-501-600均为半可育型,细胞质类型属于Owen型细胞质;MS329-N70和MS323-503-600属于半不育二型,细胞质类型不属于Owen型细胞质。【结论】已开发的VNTR特异引物的应用可以鉴定甜菜保持系和不育系的细胞质类型,且与田间育性性状调查结果基本匹配。

Abstract: 【Objective】Sugarbeet paired maintainer lines and male sterile lines′ cytoplasmic types were determined in order to provide theoretical basis and technical advice for breeding sugarbeet maintainer lines and male sterile lines.【Methods】40 sugarbeet test materials were identified using the generated VNTR specific primers TR1, TR2, TR3,and TR4, and the cytoplasmic types were separated according to the particular bands, which was combined with the research of fertility features in the field.【Results】Among the 21 materials to be selected for sterility type,the materials conforming to be Owen type were N9849-17-1,N9865-103-C1, N9857-5-1-TH1-400, MS321-C27-1-80, MS331-N70, MS343-80, MS117-3-6-4-2, MS301-500, MS351-80, MS327-70-80, MS333-70-80, MS335-N70, 2068B-2, MS151-1-16-301-400, MS317-1-8-301, MS313-506-600 and MS320-7-605-1-84. MS329-N70 was cytoplasm type N1 and MS323-503-600 was N2. Among the 19 fertile materials to be selected, 960767-201TH-1, 960764-1-11-1-1-400, OT322-C7-70-80, OT332-N70, OT352-80, OT328-70-80, BS301-13-9, OT352-80-1, OT342-80 and OT152-1-6-301-400 were found to be in line with the cytoplasm type N1, and OT302-500 was found to be in line with the cytoplasm type N2. 960766-1077-c1, OT344-80, OT118-4-5-4-4 and OT324-501-600 were Owen type. Six materials with inconsistent molecular identification results were MS351-80-1, MS341-80, OT152-1-1-1-C301, OT330-N70, OT334-70-80, and OT336-N70. The results of field investigation revealed that 960766-1077-c1, OT344-80, OT118-4-5-4-4 and OT324-501-600 were semi-fertile with Owen cytoplasmic types. MS329-N70 and MS323-503-600 were semi-sterile type Ⅱ and were not Owen cytoplasmic type.【Conclusion】The VNTR specific primers developed could be utilized to distinguish the cytoplasmic types of sugarbeet maintainer lines and male sterile lines. The results were consistent with the results of the field fertility feature identification.
