| Abstract: | Advances in crop heterosis studies using plant molecular biology techniques were summarized from the following aspects:genetic mechanisms included 1) differences in the quality and quantity of gene expression,2) changes in the primary structures of genes in F 1 and 3) the resultant genetic vibration theory; prediction method aspects contained 1)parent heterozygosity and F 1 heterosis and 2) QTLs associated with heterosis.Suggestions on the forthcoming studies were also made in the present paper. |
