Performance of Korean native black soybean lines in Korea and Taiwan

Exact estimates of genotype×location interaction are of major concern to the plant breeder in developing improved varieties. This study were conducted to compare the growth characters of Korean native black soybean lines grown in Korea and Taiwan, and to examine the selectable growth characters regardless of locations. One hundred and forty Korean native black soybean genotypes were evaluated in two different locations(Taiwan and Korea) for growth and yield characters. Average DPM(days from planting to maturity) was larger in Korea(141 days) than in Taiwan(102 days), and DPF(days from planting to flowering, 24 days) was shortened more than DFM(days from flowering to maturity, 15days) in Taiwan. One hundred seed weight was not different from two locations, and seed yield was 245, 192㎏ per 10 are in Korea and Taiwan, respectively. All the growth characters were closely related to the flowering and maturity responses in Korea, whereas plant height and pod number/plant were not in Taiwan. Significant correlation between DPF and DPM was present in Korea. But in Taiwan DPF was negatively correlated with DFM. Selectable characters regardless of locations were suggested to be DFM, plant height, and 100-seed weight in which significant correlation were found between Korea and Taiwan.
