Transcriptome analysis of a barley breeding program examines gene expression diversity and reveals target genes for malting quality improvement.

ABSTRACT:

Background

Advanced cycle breeding utilizes crosses among elite lines and is a successful method to develop new inbreds. However, it results in a reduction in genetic diversity within the breeding population. The development of malting barley varieties requires the adherence to a narrow malting quality profile and thus the use of advanced cycle breeding strategies. Although attention has been focused on diversity in gene expression and its association with genetic diversity, there are no studies performed in a single breeding program examining the implications that consecutive cycles of breeding have on gene expression variation and identifying the variability still available for future improvement.

Results

Fifteen lines representing the historically important six-rowed malt
