Multivariate analysis of agronomic characteristics in some Egyptian barley landraces: a field-based quantitative study.

ABSTRACT:

Background

Barley is a significant cereal crop in Egypt, with the potential to be used for its endurance against harsh environmental conditions, particularly in arid and semi-arid regions. The current study was conducted to assess the genetic diversity and relationships among agronomic traits of 81 Egyptian barley landraces using multivariate statistical tools like principal component analysis, cluster analysis, path analysis, and correlation analysis. The parameters recorded were days to heading, days to maturity, plant height, grain yield, spikes per square meter, grains per spike, and thousand-grain weight.

Results

The Pearson correlation heatmap showed strong relationships between the agronomic characteristics assessed in 81 barley landraces. The number of spikes per squ
