Genetic analyses of malting quality characters in barley (Hordeum vulgare L.)

Published on

The present study was undertaken to delineate the nature
of gene effects, epistasis type and estimation of genetic
parameters in barley. Mean hectolitre weight, grain protein
content and malt friability were exhibited as 58.45 kg/hl,
10.27 and 59.25 per cents, respectively. Additive x additive
effects were predominant for all the quality traits, while
dominance x dominance epistasis was also observed for
grain protein content and Kolbach index. Duplicate type
epistasis was observed for malting parameters, except
hectolitre weight and 1000 grain weight in the cross PL 426/
RD 2592. The highest significant positive correlation
coefficient (r=0.62**) was exhibited between hectolitre
weight and 1000 grain weight followed by malt extract and
filtration rate (r=0.55**) etc.
