摘　　要：通过川谷和薏苡杂交，对F1主要性状及过氧化物酶同工酶分析表明，杂种F1在植株高度、单株叶面积、生长势、光合特性等方面具有杂种优势；在不同组织、不同植物类型间过氧化物酶同工酶差异明显，薏苡的酶谱中酶带更多些。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.
