Abstract: The heterosis and combining ability for the heterosis utilization model of Tangsipingtou population×Reid population were studied with the inbred lines representing two populations.The results showed that the sca effects and heterosis of the yield properties investigated were low in the combinations of the inbred lines from the intra populations,but high in the combinations from the inter populations.The properties studied could be divided into 4 kinds of heterosis reaction models.The characteristics of the T×R heterosis model were high yield per plant,longer ear,more grains,high 1000 grain weight,but low resistance to diseases.Therefore,the inbred lines from the model populations should be improved,advanced and utilized in future breeding.It is also important to open up the new germplasms,identify the new heterosis populations,build more advanced heterosis models.
