The present invention provides a novel method for producing the rice haploid, i.e., producing the rice haploid by ricemaize hybridization. In this method, rice is used as the female parent, and the rice panicle is emasculated and then pollinated with fresh maize pollens; the emasculated panicle is sprayed with 2, 4-D solution at 50-200 mg/L 24 h after pollination, and after 15-20 days the rice panicle is cut off to collect caryopses; and the haploid embryos are obtained by dissectting caryopses asepticlly, then inoculated and cultured with MS medium, then the haploid embryos directly germinate into rice haploid seedlings. Compared with the existing main methods for producing the rice haploid, such as anther culture and isolated microspore culture, the rice haploid production method of the present invention reduces the dependence on rice genotypes, does not produce mixture of haploid and diploid plants, contains no albino seedling, and is simpler in technical operation.

The rice cultivar designated Addi Jo and its hybrids and derivatives are disclosed.

Male-sterile EGMS rice lines, both conventional and herbicide-tolerant, and their Fi hybrids are disclosed. The EGMS lines can produce Fi hybrids with high yield, desirable agronomic traits, and good milling characteristics.

A rice cultivar designated Taurus is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar Taurus. Further, it provides methods for producing a rice plant by crossing Taurus with itself or another rice variety. The invention also encompasses any rice seeds, plants, and plant parts produced by the methods disclosed herein, including those in which additional traits have been transferred into Taurus through the introduction of a transgene or by breeding Taurus with another rice cultivar.

A rice cultivar designated Ozark is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar Ozark. Further, it provides methods for producing a rice plant by crossing Ozark with itself or another rice variety. The invention also encompasses any rice seeds, plants, and plant parts produced by the methods disclosed herein, including those in which additional traits have been transferred into Ozark through the introduction of a transgene or by breeding Ozark with another rice cultivar.

A method for breeding a new variety of a ratoon rice crop and a cultivation method for the new variety of a ratoon rice crop. The method comprises: breeding a photosensitive variety of a rice crop; growing a ratoon rice crop under conditions of a long photoperiod; and taking corresponding cultivation measures to extend the growth duration of the ratoon rice crop. The invention increases grain yield while also permitting more uniform maturity of a ratoon rice crop. When compared to existing methods for cultivating ratoon rice crops, the invention greatly improves the grain yield and quality of a ratoon rice crop, and has economic and social benefits.

Monocot seeds treated with various cyanobacterium compositions, methods of making the treated seeds, and methods of using the seeds to improve monocot plant growth, biomass, nitrogen uptake, nutrient uptake, lateral root growth, lateral root hair growth, vertical root growth, root branching and/or yield are provided.

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.

Plants, seeds and tissue cultures of the long grain aromatic rice cultivar RT22J502, and methods for producing a rice plant by crossing a rice plant of rice cultivar RT22J502 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.

The present invention discloses mutations in the genes encoding starch synthases and also in starch branching enzymes associated with enhanced dietary fibre and resistant starch levels in the endosperm of a suitable variety of rice. The dietary fiber and resistant starch are enhanced to an extent to significantly reduce the hydrolysis index values of the rice grains to 35%-40%. These rice varieties are in great demand for diabetic population and provide a number of other health benefits such as reduced body weight gain, cardiac health and colon health. As this strategy does not involve the use of genetic manipulation technologies, it can be directly employed in the rice breeding programmers without any restrictions.
