The present disclosure provides a rice planthopper-sensitivity gene BGIOSGA015651 and the use thereof. The applicant found a gene BGIOSGA015651 for regulating rice planthopper-resistance by studying on rice varieties BG1222 and TN1. The gene expression level of BGIOSGA015651 in the insect-resistant variety is hundreds of times or more different from that of the insect-susceptible variety. The expression of this gene can be reduced or knocked out by molecular breeding methods or genetic engineering methods, resulting in that the insect-susceptible plant can obtain high insect-resistance. The resistance level of the insect-susceptible rice variety TN1 is of level 9 before knock-out, and the resistance level thereof is significantly increased to level 0-1 after the rice planthopper-sensitivity gene BGIOSGA015651 is knocked out. The gene and the encoded protein thereof can be used for plant genetic improvement, and the obtained rice for breeding can be widely promoted in a wide range of rice growing areas, and has high economic values and outstanding ecological benefits.

A method for breeding polyploid two-line hybrid rice includes determining a tetraploid rice photo thermosensitive genic male sterile line with the gene characteristic of PMeS (polyploid meiosis stability) and a tetraploid rice restoring line with the gene characteristic of PMeS; hybridizing and matching by indica sterile/japonica restoring or japonica sterile/indica restoring hybrid combination; preparing a tetraploid rice hybrid by adopting a tetraploid rice photo thermosensitive genic male sterile line and a tetraploid rice restoring line; and breeding a stable tetraploid rice hybrid combination which is determined as the polyploid two-line hybrid rice combination. The breeding method disclosed by the present invention utilizes the strong heterosis of polyploid rice, and transforms the existing diploid heterosis into the heterosis of polyploid two-line hybrid rice; and by adopting the method disclosed by the present invention, a new polyploid two-line hybrid rice variety with large ears, large grains and high yield can be bred.

The present disclosure provides a method for treating rice. The method comprises the steps of: providing a domestic rice crop plant and at least one ACCase-inhibiting aryloxyphenoxypropanoate herbicide selected from the group consisting of quizalofop or an ester thereof, haloxyfop, fluazifop or an ester thereof, clodinafop, clodinafop-propargyl, diclofop, and diclofop-methyl; applying an effective amount (measured in g AI/Ha) of the at least one aryloxyphenoxypropanoate herbicide to the domestic rice crop plant, post-emergence; thereby creating a treated rice plant; and growing the resulting treated rice plant.

This invention describes a new method to generate wheat seed. The process involves the delivery of pollen of the male parent at will, as available either in a preserved pollen bank, or using real-time collection from male plants as they become available. Desired pollen is delivered to fertile females during the period when viable pollen from the females and locally proximal unrelated plants is not being released. The delivered male pollen is in such amounts and fortuitously timed that it preferentially pollinates the females. Such fortuitous timing may involve the intentional application of pollen to females a day or two prior to female parent pollen becoming viable, and/or during several periods wherein female parent pollen and/or other proximal plant pollen is not being shed.
