Why are there so many phenotypic differences between woody and herbaceous species? To this day, scientists have failed to provide satisfying answers. We have crossed a tall, woody, late flowering cabbage accession (Jersey kale) with a small, rapid flowering cabbage accession (TO1000) and obtained 200 F2 accessions in tissue culture (see picture), allowing multiple experiments of the same genotype over time. Our objective it to find genomic regions associated with the phenotypic differences observed in the F2 generation (QTL experiment). A number of phenotypic differences that interests us are woodiness, drought stress resistance, flowering time, developmental speed, stem elongation, ageing, and plant herbivory.
