Investigation of the Field Performance of Progenies Obtained by a Non-vernalization-grafting Floral Induction Method in Terms of Application to Cabbage Breeding and Seed Production

Floral induction by grafting without vernalization treatment (NV method) has potential to shorten breeding times and diversify the seed production of cabbage, an important leafy vegetable with a long absolute low temperature exposure requirement for its floral induction. However, it is unknown whether NV method can be actually used cabbage production. This because method’s effect on field performance obtained progenies not been investigated, as opposed conventional treatment. Therefore, in this study we compared effects two different methods agricultural traits progenies. Two clonal lines ‘Watanabe-seiko No.1’ were experiment. In two-year experiment, observed consistent vegetative growth; however, almost no either or reproductive growth observed. was further supported similar expression levels FLOWERING LOCUS C homologs at young seedling stage. Pollen formation confirmed regardless method. conclusion, seeds are likely show same those indicates direct applicability
