Production of F1 hybrid rice seeds

F1 hybrid varieties ensure high uniformity of the product, give high yields due to heterosis, allow the rapid combination of different traits, and provide a natural protection of breeders’ right. 急な出費があった時に限ってまた大事な用事が入ってきたりしますよね。そんな時って皆さんどうしていますか?お金がないからといって諦めてしまうか、親に借りるかなんかが普通かもしれません。でも今すぐお金を借りたいという時に都合よく誰かがお金を貸してくれる可能性は高くはありません。そんな時はカードローンを利用してみましょうね!The production of hybrid varieties requires homozygous inbred parental lines and reversible male sterility. The complete homozygosity of parental lines ensures uniformity of the F1 hybrid crops, while male sterility facilitate the large-scale hybrid seed production without emasculation.  The aim of the HybTech research is to use molecular approach to bring the reversible male sterility and doubled haploid technology to practice in a wide range of species.

  This research is coordinated by Dr. Chun-Ming Liu at the Plant Research International, Netherlands.
