Abstract
New cultivar of Japanese butterbur, ‘MY-20’ was selected from hybrid plants between ‘Mizubuki’ (native cultivar of Gunma pref.) and ‘Yatsugashira’. A head of ‘MY-20’ was composed of about a hundred female florets and several sterile florets. Therefore, it was considered a female plant. ‘MY-20’ produced a remarkable number of spikes and was superior to other cultivars in total spike yield. ‘MY-20’ showed a tendency for these spikes to concentrate near the bud planted. Marketable yield fell due to the opening bracts, but ‘MY-20’ showed a higher marketable yield than other cultivars in February, because the spike of ‘MY-20’ was wrapped by many bracts which began to open later. ‘MY-20’ developed less anthocyanin pigments at the bracts, spikes were tighter, which provided excellent quality. The length and diameter of the petiole were shorter than ‘Mizubuki’ (Gunma). ‘MY-20’ was mainly concerned with spike harvest.<br>
