Breeding for Quality . PLS 664 Spring 2007. End Use Quality - what is it?. SRW Wheat - An Example. Typical Quality Evaluation Scheme. F4:6 lines from Preliminary Trials - send 100-200 g to USDA Quality Lab for micro tests F4:7 lines - same
R2 = .44
Where S = selection differential
and h2 = heritability
Where i = selection intensity
and P = phenotypic standard
Given that h2 and P are parameters of
the population we are working with, what
can we do to increase progress?
We must increase selection intensity.
