Genetic diversity analysis of proso millet (<i>Panicum miliaceum</i> L.) germplasm resources based on phenotypic traits and SSR markers.

ABSTRACT:

Introduction

Germplasm resources are vital for food security and agricultural sustainability, providing the basis for seed industry innovation.

Methods

In the present study, 1,582 proso millet (Panicum miliaceum L.) germplasm resources, comprising landraces, cultivars, wild varieties, and foreign varieties, were sown in early June 2024 at the Yulin Minor Grain Comprehensive Experimental Demonstration Station. Subsequently, the genetic diversity was analyzed according to 14 agronomic, 5 yield, and 3 grain traits.

Results

Significant phenotypic diversity was observed: agronomic trait diversity indices ranged from 0.15 to 2.10, with straw weight per plant showing the highest variation coefficients (60.03%). Yield traits exhibited diversity indices of 1.95-2.08 and
