Abstract:
Nine floral characters of 90 soybean materials(including 32 cultivated,19 semi-wild and 39 wild soybean)were determined.The broad-sense heritability and the genetic coefficient of variation were calculated.The results showed that the estimated broad-sense heritability of all the floral characters were high,while the genetic coefficient of variation were relative low except for stigma exertion length.The average length of all nine floral characters showed a tendency that cultivated soybean>semi-wild soybean>wild soybean,while the coefficient of variation showed a tendency that wild soybean>cultivated soybean>semi-wild soybean.The genetic coefficient of variation of the stigma length had little difference among wild soybean,semi-wild soybean and cultivated soybeans,but the value was relatively higher,which suggests that this character has a good selective potential.The genetic coefficient of variation value of styles length of wild soybean was higher than that of cultivated and semi-wild soybean,suggesting that wild soybean has a wider range of variation.Soybean materials derived from different geographical region could be organized into the same cluster,suggesting that geographical difference does not affect floral characters significantly as evolutionary type.
