The herbicide-tolerant rice cultivar designated PVL01 and its hybrids and derivatives are disclosed. The present invention provides a method for producing rice, wherein said rice is tolerant to a quizalofop herbicide or tolerant to a tepraloxdyim herbicide; wherein said rice belongs to any of (a) variety PVL01 or (b) a hybrid, derivative, or progeny of PVL01. Further provided are methods for producing a hybrid or a new variety by crossing the rice variety PVL01 with another rice line, one or more times. In another embodiment, this invention allows for single-gene converted plants of PVL01. In another embodiment, this invention provides regenerable cells for use in tissue culture of rice plant PVL01.

Plants, seeds and tissue cultures of the hybrid rice HR180001, and methods for producing a rice plant by crossing a rice plant of hybrid rice HR180001 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.

Plants, seeds and tissue cultures of the hybrid rice HR180002, and methods for producing a rice plant by crossing a rice plant of hybrid rice HR180002 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.

The herbicide-tolerant rice cultivar designated PVL02 and its hybrids and derivatives are disclosed.

A rice cultivar designated M-210 is disclosed. The invention relates to the seeds of rice cultivar M-210, to the plants of rice M-210 and to methods for producing a rice plant produced by crossing the cultivar M-210 with itself or another rice variety. The invention further relates to methods for producing a rice plant containing in its genetic material one or more transgenes and to the transgenic rice plants and plant parts produced by those methods. This invention also relates to rice cultivars or breeding cultivars and plant parts derived from rice cultivar M-210, to methods for producing other rice cultivars, lines or plant parts derived from rice cultivar M-210 and to the rice plants, varieties, and their parts derived from the use of those methods. The invention further relates to hybrid rice seeds and plants produced by crossing the cultivar M-210 with another rice cultivar.

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 rice cultivar designated M-210 is disclosed. The invention relates to the seeds of rice cultivar M-210, to the plants of rice M-210 and to methods for producing a rice plant produced by crossing the cultivar M-210 with itself or another rice variety. The invention further relates to methods for producing a rice plant containing in its genetic material one or more transgenes and to the transgenic rice plants and plant parts produced by those methods. This invention also relates to rice cultivars or breeding cultivars and plant parts derived from rice cultivar M-210, to methods for producing other rice cultivars, lines or plant parts derived from rice cultivar M-210 and to the rice plants, varieties, and their parts derived from the use of those methods. The invention further relates to hybrid rice seeds and plants produced by crossing the cultivar M-210 with another rice cultivar.

The present disclosure relates to a fertility gene and the use thereof, and relates to the biotechnology field, particularly to a method of plant hybrid breeding including creation of a sterile line and preparation of hybrid seeds, more particularly to a fertility gene FL2, a mutant thereof and use thereof in hybrid breeding.

The present disclosure relates to an expression vector for restoring male sterility in a plant. The expression vector comprises a regulatory region sequence operably linked to a heterologous nucleotide sequence.

A rice cultivar designated Calaroma-201 is disclosed. The invention relates to the seeds of rice cultivar Calaroma-201, to the plants of rice Calaroma-201 and to methods for producing a rice plant produced by crossing the cultivar Calaroma-201 with itself or another rice variety. The invention further relates to methods for producing a rice plant containing in its genetic material one or more transgenes and to the transgenic rice plants and plant parts produced by those methods. This invention also relates to rice cultivars or breeding cultivars and plant parts derived from rice cultivar Calaroma-201, to methods for producing other rice cultivars, lines or plant parts derived from rice cultivar Calaroma-201 and to the rice plants, varieties, and their parts derived from the use of those methods. The invention further relates to hybrid rice seeds and plants produced by crossing the cultivar Calaroma-201 with another rice cultivar.
