Characteristic Performance of F_1 Hybrid of Jobstears (Coix lacryma-jobi) and C.lacryma-jobi var.friamentacea and Inheritance of Stigma Colour / 中草药

The main characters and peroxidase isozymes of Coix lacryma-jobi L. and C.lacryma-jobi var.friumentacea Makino and their F1 hybrid were analyzed. Results showed that the plant height, area of leaves per plant, growth performance, and photosynthetic characteristic of F1 hybrid all exceedcd its parents. Bands of iso-peroxidase were different between F1 hybrid and itsparents. There were more band s of isoperoxid ase in the C.lacryma-jobi var. friumentacea Makino than in C.lacryma-jobi L..This is the first report to show the inheritance regularity of stigma colour which was controlled by two complementation genes.
