Genetic diversity for malting quality in barley (Hordeum vulgare L.)

Published on

Genetic diversity for malting quality was studied on a set
of 131 barley genotypes of indigenous and exotic origin
representing both two and six row types. Observations
were recorded on seven grain and seven malt traits. The
study revealed that lot of variability exists in material for
all malting quality traits. It was also observed that in
general two-row barleys have better malting quality.
Sources for different quality traits were identified for use
as donors in breeding programme. The clustering analysis
revealed four major clusters amongst the genotypes with
varying standards for quality traits. The non hierarchical
Euclidean cluster analysis indicated that genotypes with
very good malting quality were grouped in one cluster.
Clustering pattern based on Ward’s minimum variance
method also revealed four major discrete clusters among
the genotypes studied.
