In this study, the hybrids field characters of 9 inbred lines of corn were analysised, and the sequence of genes BT2 and RbcS was cloned. The expression of heterozygous has been analysised by RT-PCR for looking for heterozygous loci which lead to high expression. For the mechanism of heterosis and utilization basis. The main results are followed:
1. The variances of 5 traits of 35 hybrid combinations were analysed. The results showed that the variances among combinations were very significant. The resul...
