Studies on Breeding Sweet Potato Varieyies Adapted to True Se ed Planting. : I.Flowering Habit, Seed-Seting and Adaptability of Natural Flowering Population to True Seed Planting

Crop Physiology of Sweetpotato

“…Sweetpotato cultivars are sensitive to photoperiod and differ in their flowering habit. Compared with vine cutting planting, storage root yield is significantly reduced in true seed planting (Hirosaki and Ono 1970;Yamakawa and Sakamoto 1980a,b, 1981Schultheis and CantHffe 1994). Cultivars that do not flower readily can be stimulated to flower by various techniques (Wang 1975).…”
