SSR Marker Identification and Character Analysis of Perilla F1 Hybrid
The identification of real F1 hybrids is the basis for developing Perilla hybrid breeding and constructing genetic research groups.In this study,hybrid combinations were prepared with"Jizi 1"as the female parent and"Jizi 2"as the male parent.Simple sequence repeat(SSR)markers were used to identify the authenticity of F1 hy-brids.And the agronomic traits and quality traits of the parents and real hybrids were analyzed.The results showed that among the 29 pairs of SSR primers,there was 1 pair of primer ZS-14,which was stable in amplification,clear bands,capable of distinguishing parents and identifying real hybrids.A total of 46 real hybrids were identified us-ing this primer.Hybrid plants integrated the advantages of both parents in traits such as plant height,leaf length,leaf width,leaf weight and soluble sugar.The research results provide guidance for the authenticity identification and cross breeding of Perilla hybrids.
