Varieties used for comparison: 'Koto' and 'Koban'
Summary: The majority of flowers of 'Koma' are homomorphic while they are mainly heteromorphic in the reference varieties. 'Koma' flowers slightly earlier than 'Koto'. The seed of 'Koma' is slightly shorter than that of 'Koto' and slightly narrower than that of 'Koban'. The seed of 'Koma' is black while it is black and brown in 'Koban'. 'Koma' has a higher seed density than the reference varieties. 'Koma' matures slightly sooner than 'Koban'.
PLANT: diploid, open and self pollinated
LEAF: arrow shaped
FLOWER BUD: absent or very weak intensity of anthocyanin colouration
INFLORESCENCE: semi compact terminal umbels and single axillary racemes
FLOWER: mainly homomorphic
SEED: black, rounded to well filled, wings absent
Origin & Breeding History: 'Koma' originated from the cross made in 1998, under greenhouse conditions, of BM94199 X Fagopyrum homotropicum accession K950818-3 at the Crop Diversification Centre, Agriculture & Agri-Food Canada, Morden, Manitoba. The resultant progeny was backcrossed 5 times to F. esculentum line BM94199 and one time to F. esculentum line BM94364. A single plant, designated BX98-0084-14-1-0-0 was derived from the F4 progeny. Selection criteria included uniform and high seed yield and superior flour functionality characteristics.
Tests & Trials: Tests and trials were conducted during the summers of 2004 and 2005 in Morden, Manitoba. Plots consisted of 6 rows, with a row spacing of 17 cm and a row length of 5 metres. There were more than 500 plants per plot. There were 4 replications arranged in an randomized complete block design.
