Genetic diversity evaluation and selection methods of sweet potato hybrid F₁ population based on SSR markers and phenotypic detection.

ABSTRACT: Sweet potato (Ipomoea batatas (L.) Lam.) is a vital global crop, with breeding focused on both high starch and high yield. Hybrid populations are crucial for genetic improvement, but research on sweet potato hybrid F₁ populations remains limited. To explore the genetic laws of important traits in hybrid progenies, this study investigates the genetic diversity and efficient selection methods of the hybrid F₁ population from crossing between Yushu No.12 (high starch content) and Luoxushu No.9 (high yield) using phenotypic detection and SSR markers. Coefficients of variation, genetic distances, and similarity coefficients results showed that the F₁ population has rich genetic diversity. The parents and F₁ progenies could be clustered into 4 and 6 ca
