Dendrocalamus brandisii is an essential species of bamboo in Yunnan Province., China, with a wide range of uses and high economic and ecological value. Understanding its genetic diversity and genetic structure characteristics provides a theoretical basis for the conservation, utilization, and genetic improvement of D. brandisii resources. The genetic diversity and population structure of 70 samples from 7 geographical populations in Yunnan Province were studied by simplified genome sequencing technology. The results showed that 514 318 SLAF tags were obtained through sequence comparison and screening, among which 234 305 were polymorphic SLAF tags, 1 651 130 population SNPS were obtained, and 375 389 SNPS with high consistency were obtained. The average completeness and heterozygosity of SNPs were 54.91% and 18.78%, respectively, with a homozygosity rate of 81.22%. |
