Relationship of Visual Differences in Greenness with Chlorophyll Content and Seed Yield in Soybeans

Seventeen Korean soybean varieties and 28 introductions from several countries were studied to determine the difference in the amount of chlorophyll and the relationships of visual observation in green pigmentation with chlorophyll content and seed yield. The amount of chlorophyll a, chlorophyll b and total chlorophyll in tested varieties showed considerable variation. The chlorophyll a ranged from 2.44 to 7.32 mgr and the chlorophyll b from 2.88 to 9.16 mgr. In total chlorophyll, the variety Lincoln introdued from U.S.A. had much higher content as 16.22 mgr and the variety P_5 from Vietnam showed much lower content as 5.32 mgr than other varieties, respectively. Highly significant relationships were found for chlorophyll a to chlorophyll b and for chlorphyll a and b to total chlorophyll. However, no relationship between visual differences in greenness and total chlorophyll with seed yield in this experiment suggest that visual observation could not accounted for the significant means to determine the quantitative differences of chlorophyll and seed yield in soybeans.
