The effect of low temperature treatment on DNA methylation level decrease revealed some variety differences. The DNA methylation level in stem apices of the spring radish cultivar'Duanye 13'was somewhat easy to be decreased by low temperature treatment, but that of the winter radish cultivar'Yidianhong'did not decrease when the germinated seeds were treated at 10℃ for 10 days.

萌动种子低温处理降低DNA甲基化水平的效果在品种间存在一定差异，春性品种'短叶13'其DNA甲基化水平比较容易被降低，而冬性品种'一点红'的萌动种子在10℃下处理10d尚不能降低其DNA甲基化水平。

Mitochondrial cytochrome b sequence were used to study the molecular evolution and phylogeny of Anser cygnoides(15 breed of Chinese goose), Anser anser(2 breed of domestic European goose) and Anser albifrons(the lesser white-fronted goose, Genbank accession number AF363031). Sequence analysis revealed that there were 29 variable sites and 4 haplotypes in 45 sequences, nucleotide diversity and haplotype diversity were 0.0068,0.45 respectively, insertion/deletion or frameshift mutation were not found in Cyt-b gene sequences(1143bp).
