The nominating institution Chinese Academy of Sciences on the breakthrough:

Exploitation of heterosis is one of the most important applications of genetics in agriculture. Dr. Bin Han used an integrated genomic and forward genetic approach to construct a genome map for elite hybrid rice varieties and revealed the genomic architecture of rice heterosis. He identified that the accumulation of numerous rare superior alleles with positive dominance is an important contributor to the heterotic phenomena, which will be useful information for future crop-improvement program.
