Flowering characteristics and grain yields in Korean landraces of buckwheat(fagopyrum esculentum moench)

Buckwheat(Fagopyrum esculentum Moench) has been a popular favorite food crop in Korea for a long time. Ninety five Korean landrace populations were planted on July 29, 1988 and August 3, 1989 and evaluated their flowering characteristics and kernel productivity in Suwon. The initial flowering date was August 25 with mean flowering date of August 30, and mean maturing date was October 6, 1988. The range of the landrace populations was 12 to 14 days for flowering date, and only four days for maturing date. The mean perccntage of pin type flower plant was 49.3% being reached near the theoretical percentage. For kernel productivity, the pin type produced 12.3g per plant and the thrum type 13.3g per plant. The mean kernel yield of the populations was 12.8g per plant. The best landrace population produced 28g per plant being 1,800kg per hectare. The coefficient of variation was 0.3%, 0.5% for flowering and maturing dates respectively, 21.6% for pin type plant percentage, and 52.6-54.9% for kernel yield per plant. Thus it would be expected to develop superior cultivars with higher kernel productivity.
