In order to obtain the genetic information on the quantitative characters of black seeded soybeans, which would be needed to improve selection efficiency for breeding high yielding genotype, 45 varieties of black seeded soybeans collected in Chonnam, Korea were grown and variations of several important characters were observed. Heritability of each observed character, phenotypic and genotypic correlations among the characters and contribution of each yield component on grain yield through path coefficient analysis were estimated. Both number of pods per plant and 100-seed weight showed not only high heritability but also highly significant phenotypic and genotypic correlation with seed yield, and hence it was desirable to select plants with more number of pods per plant and higher 100-seed weight than raise seed yield of black seeded soybeans collected in Chonnam. In addition, number of pods per and 100-seed weight were proved to be the most influential variables on the viability of seed yield by path coefficient analysis. Since these showed the high heritability of number of pods per plant, selection of plants with higher 100-seed weight would be more efficient for breeding high yielding genotype.

A total of 135 black seeded soybeans genotypes were collected in 45 island locations from January to May 2001. Seeds of 135 genotypes collected were analyzed for crude protein and fatty acid compositions. The crude protein content was averaged to be 40.75%, and was ranged from 34.70% to 44.20%. The average palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid content were 11.41%, 3.93%, 22.75%, 53.55%, and 8.35%, and the ranges of those were 9.00% to 14.40%, 2.90% to 5.00%, 22.75% to 26.50%, 50.30% to 57.20% and 6.7% to 11.20%, respectively. Heritabilities of palmitic acid, oleic acid, linoleic acid, and crude protein were higher, but that of stearic acid and linolenic acid were relatively lower, Crude protein content was correlated positively with oleic acid content, whereas it was correlated negatively with linoleic acid, palmitic acid, stearic acid, and linolenic acid contents.

There has been known C3G (Cyanidin-3-Glucoside), D3G (Delphinidin-3-Glucoside), and Pt3G (Petunidin-3-Glucoside) were main anthocyanin pigments in black-seeded soybean. Anthocyanin contents of total 1,032 black-seeded soybean germplasms were analyzed by HPLC. Average of total anthocyanin content was 11.67 mg/g on the all materials ranged from 0.54 to 23.45 mg/g. Mean value of C3G, D3G, and Pt3G contents in all black-seeded soybeans were 8.81, 1.78 and 0.79 mg/g, respectively. Environmental conditions influenced anthocyanin contents during seed development. Delayed flowering, especially of later maturing germplasms, has been showed to result in increased anthocyanin content. So, prolonged maturation period germplasm is generally higher than that of shorten genotypes. It may be concluded that the higher levels of anthocyanin content was associated with the late dates of harvest maturity. Also larger seeds showed high anthocyanin contents than smaller. That inclination is similar in C3G's occasion because C3G content contribute highly to total anthocyanin content than other pigments.
