Conclusion on population breeding towards resistance to plant diseases
●Populations created by natural and mass selection sometimes have advantages compared with the mean of the parents
● but plant health is neither optimal nor acceptable.
●Selecting the right parents for CCPs is crucial●The way forward is mixtures of multiple lines,
preselected for resistance to the major plant diseases

Conclusion quality sorting● Never forget that any seed cleaning is also see sorting, including TKW● Protein concentration can be increased in populations by seed sorting● Gravity sorting and colour sorting can be used, but NIT-single seed
sorting is the most effective● Effects can be improved by decreasing environmental effect, and by
improved calibration of the equipment● Protein improved population suffers a yield penalty of about 10% per
protein percent-point. Also total protein yield decreases● Selecting for protein quality would be better that selecting for protein
content, since this most likely can be done without yield loss● Selecting the right parents for CCPs is easier and more efficient than
seed sorting afterwards
