图2 4个紧密连锁标记对聚合DH系基因型鉴定结果 a: 与cqDTFA7a连锁标记G1803鉴定结果; b: 与cqDTFA7a连锁标记IA7-4鉴定结果; c: 与cqDTFC8连锁标记S035鉴定结果; d: 与cqDTFC8连锁标记SNP11鉴定结果。M为marker, 4512为早花亲本, No.5246为晚花亲本, 两者基因型为标准, 与4512带型相同则认为含有早花位点, 与5246带型相同则不含。箭头所指的是7个聚合DH系在4个标记下都与4512带型一致。

Fig. 2 Identification result of the polymerized DH lines genotype used four closely linked markers a: identification results of G1803 linkage mark with cqDTFA7a; b: identification results of IA7-4 linkage mark with cqDTFA7a; c: identification results of S035 linkage mark with cqDTFC8; d: identification results of SNP11 linkage mark with cqDTFC8. M is marker, 4512 is the parent of early flowering, and 5246 is the parent of late flowering. Both genotypes are considered as standard, and the same as No.4512 band type is considered to contain early flowering locus, while the same as 5246 band type is not considered to contain early flowering locus. The arrow points to seven polymerized DH lines that are consistent with the 4512 band type under four markers.
