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

Table 4

Genetic diversity and differentiation of sugarcane accessions between common and new parents, estimated by POPGENE (version 1.31).

Group	Clones size	Ht	Hs	Dst	Gst	Nm
Common parents	64	0.190	0.158	0.032	0.171	2.429
New parents	51	0.214	0.156	0.058	0.273	1.335
Total	115	0.176	0.159	0.017	0.095	4.762

Mean values of total gene diversity (Ht), gene diversity within populations (Hs), gene diversity between populations (Dst), gene differentiation coefficient (Gst), and estimates of gene flow from Gst (Nm) were obtained by (1 − Gst)/2Gst.
