Identification and genetic diversity analysis of specific walnut F1 progeny based on SSR molecular markers: taking heart-shaped walnuts and Jinghong 1 as examples.

ABSTRACT: To gain a deeper understanding of the genetic diversity and authenticity of natural pollinated F1 progeny populations of specific walnuts (heart-shaped walnuts and Jinghong 1), as well as the genetic relationship between F1 offspring and their maternal parent. 32 heart-shaped walnut F1 offspring, 45 Jinghong 1 F1 offspring, and their maternal parent were selected as materials, and 14 pairs of SSR markers were used for genetic diversity and parent-child relationship analysis. The results showed that Jr05, Jr11, Jr29, Jr44, Jr45, Jr52, Jr53, Jr55, and Jr56 could be used as SSR markers for the identification of hybrid offspring in heart-shaped walnuts. Jr35, Jr40, Jr45, Jr50, Jr52, and Jr53 could be used as SSR markers for the identification of hybrid offspring of Jinghong 1. XX21 had the clo
