Genetic Diversity Analysis of Sugarcane Parents in Chinese Breeding Programmes Using gSSR Markers

Table 2

The allele detection results of 5 SSR markers used for evaluation of 115 sugarcane accessions.

Primer name	Number of alleles	Number of rare alleles	Range of allele size (bp)	Major allele		PIC
				Size (bp)	Frequency (%)
SMC334BS	19	6	136–169	147	66.10	0.889
SMC336BS	26	15	136–192	168	59.10	0.897
SMC36BUQ	11	8	101–147	122	39.10	0.753
SMC286CS	15	6	123–169	146	46.10	0.865
SMC569CS	17	11	159–238	220	66.10	0.779
Average	17.6	9.2				0.837

Rare allele means that the frequency of the allele is less than 5.0%; the major allele accounts for the highest proportion in all alleles.
