Comprehensive phenotyping of 1,807 Indian barnyard millet (<i>Echinochloa frumentacea</i> Link) accessions from Indian national genebank: unlocking diversity for core set development.

ABSTRACT:

Introduction

A comprehensive characterization of 1,807 barnyard millet (Echinochloa frumentacea Link.) accessions conserved in the Indian National Genebank (INGB) was conducted to assess genetic variability and develop a representative core set.

Methods

Thirteen qualitative and ten quantitative traits were evaluated. Five core sets were created using Core Hunter 3, utilizing optimization approaches to enhance representativeness and diversity. Comparisons were made between the entire collection and the developed core sets using diversity indices, statistical parameters, correlation analysis, and principal component analysis (PCA).

Results

Significant diversity was revealed across traits. Predominant qualitative traits included pyramidal inflorescence shape (89%)
