Abstract:

In order to find out the cytoplasm types of some sterile line and maintainer line materials in the process of sugar beet breeding, it provides a guiding direction for the next breeding work. Molecular marker primer TR1 was used to identify the molecular level of 30 test materials cytoplasm types, and to compare the fertility traits in the field. The results showed that the PCR electrophoresis bands of maintainer line 960767 and sterile line N9848 were 750,500 bp.We named these cytoplasm types as N1 and S,respectively.And 750 bp bands were detected by T152,T328,T334,T306,T360,as N1 cytoplasm.The 500 bp bands detected were T766,T154,N122,I-1,B-3,Z-1,41419,10320,B-3-23,S865,S301,S151,S327,S333,S115,S305,S153,S359,S137,S163,and S313,inferred to be S type cytoplasm.The materials for the bands detected between 500 bp and 750 bp were T302,and T116.Because T302 also had the ability to maintain the sterility of S301 in field investigations,T302 and T116 were classified into another type,N2 cytoplasm type.Some plants with 500, 750 bp of materials were T302, I-1 and B-3, which included both normal and Owen cytoplasm were characteristic materials. The results of field pollen fertility survey T766, T154, N122, I-1, B-3, Z-1, 414191, 10320 and B-3-23 were all fertile, but their cytoplasm type was identified to belong to S type cytoplasm. According to molecular identification and field fertility trait survey, the results of most materials were consistent with the results of fertility trait survey. Some materials had inconsistent molecular identification and fertility trait results, requiring further adjustment of the selection direction.
