Observational analysis reveals correlations between grain yield and effective tillers in hulless barley genotypes, suggesting important selection criteria.
Key Points
High heritability and genetic advance were found for number of grains per spike, number of effective tillers, and grain yield.
PCA revealed that the first component explained 31.29% of variance, correlating with key growth traits.
Cluster analysis identified six distinct clusters, with some containing high-yielding hulless barley genotypes.
Significant positive correlations were observed between grain yield and traits like effective tillers and biological yield.
