Morphological features of the Mv9kr1-‘Kriszta’ line ‘179’ and the parental lines S. cereanum ‘Kriszta’ and hexaploid wheat genotype Mv9kr1 in 2015 and 2019. Values are the means ± standard deviations of 10 measurements and were compared to those of the parental wheat line Mv9kr1. TKW: thousand kernel weight, PB: pre-breeding, LI: low-input.
