| Abstract: | Tartary buckwheat (Fagopyrum tataricum) is a highly nutritious crop that is widely grown in Asia, but the flour contains a large portion of the hull if it is ground
with industrial processing since the hull is very hard to remove as it adheres to the testa layer of the groat. Rice-Tartary,
a particular type of Tartary buckwheat, has seeds with a loose hull and the presence of splits on the sides of the seeds that
make dehulling easily. The present study reports on the first attempt of crop improvement in Tartary buckwheat breeding through
hybridization. Hybrids were obtained by hybridization of crosses between Tartary buckwheat and Rice-Tartary. Additional crosses
were made among selected progenies of these crosses. Based on progeny analysis of the F1, F2, and F3, the character of Rice-Tartary, as exhibited as the presence of splits on the sides of the seeds, is controlled by one gene
which is homozygous recessive. A Tartary buckwheat breeding program has been conducted for 6 years based on these crosses.
Advanced lines with easy dehull and yield potential are at the stage of ready for yield trials. Production of easy dehulling
Tartary buckwheat in the future could boost Canada’s domestic and international markets. |
