The hybrid offspring ♀ × showed heterosis in terms of growth and disease resistance. The mitochondrial genome is 16,629 bp in length and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. The difference of total length is mainly caused by the difference of length in non-coding region. The nucleotide base composition is A = 29.15%, G = 15.62%, T = 26.91%, C = 28.32%, A + T = 56.06%, and C + G = 43.94%. The phylogenetic analysis using neighbour-joining (NJ) method showed that the hybrid offspring has a closer relationship to ×
杂交后代♀×在生长和抗病性方面表现出杂种优势。线粒体基因组长度为16,629 bp,由13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个控制区组成。总长度的差异主要由非编码区长度的差异引起。核苷酸碱基组成为A = 29.15%,G = 15.62%,T = 26.91%,C = 28.32%,A + T = 56.06%,C + G = 43.94%。使用邻接法(NJ)进行的系统发育分析表明,杂交后代与×的关系更密切。
