'Haruwakaba'was bred from 48 plants by one cycle of mass selection from 480 plants of the breeding line 'Tsukikei 2'. The dry matter yield of 'Haruwakaba' was 5% higher than that of a standard cultivar 'Makiwa-kaba' in Hokkaido. Persistency of 'Haruwkaba' was better than that of 'Makiwakaba' and 'H-isawakaba', especially in the 3rd and 4th harvest years. 'Haruwakaba' is resistant to Verticilium wilt and its rate of wilt-resistant plants exceeded 60%. 'Haruwakaba' is similar in resistance to common leaf spot to 'Makiwakaba'. Plant type of 'Haruwakaba was spread type and 'Haruwakaba' was less tolerant to lodging than 'Makiwakaba'. 'Haruwakaba' had better winter hardiness, better sprouting and better plant vigor in spring than'Makiwaka'. 'Haruwakaba' is more dormant than 'Makiwaka' and plant vigor of 'Haruwakaba' in autumn is lower than that of 'Makiwakaba'. 'Haruwakaba' includes plants with variagated flower color and blooms as early as 'Makiwakaba'. It belongs to early maturing group of cultivars. 'Haruwakaba' was similar in seed yield and chemical composition to 'Makiwakaba'. 'Haruwakaba' is recommended for cultivation in the whole region of Hokkaido.},
