A method for increasing production of hybrid seed of bee-pollinated crops, such as alfalfa and soybean at predetermined hybridity levels. Hybrid seed is produced using female and pollenizer plants at a selected ratio of female plants to pollenizer plants. The female plants and the pollenizer plants are intermingled in the hybrid seed production field. Prediction of percentage of hybridity at various female to pollenizer ratios allows for selection of a ratio of female plants to pollenizer plants to provide seed at a test percentage of hybridity. The percentage of hybridity may be increased post-harvest by employing techniques using seed properties such as size differential, color or density to remove a higher percentage of non-hybrid seed. The hybrid seed product is maximized at various hybridity levels. Planting according to subrows allows for separate harvesting of intermingled crops. Testing the hybrid seed product provides verification of percentage of hybridity.

Methods for producing a hybrid seed product

An inbred corn line, designated D050212, the plants and seeds of the inbred corn line D050212, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line D050212 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line D050212 with another corn line or plant and to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic corn plants produced by that method. This invention also relates to inbred corn lines derived from inbred corn line D050212, to methods for producing other inbred corn lines derived from inbred corn line D050212 and to the inbred corn lines derived by the use of those methods.

Inbred corn line D050212

Disclosed is the seed of an inbred corn line, designated DS-046358, a sample of which is deposited under ATCC Accession No. PTA-9052. Also disclosed are plants, or parts thereof, grown from the seed of the cultivar, plants having the morphological and physiological characteristics of inbred corn line DS-046358, and methods of using the plant or parts thereof in a corn breeding program.

Plants and seed of inbred corn variety DS-046358

Disclosed is a hybrid alfalfa seed deposited as ATCC Accession Number PTA-2759. Also disclosed is a hybrid alfalfa plant or part thereof derived from the seed deposited as ATCC Accession Number PTA-2759. A method of obtaining commercially acceptable production of alfalfa seed having at least 75% hybridity by planting male sterile and male fertile seed at a ratio of about 4:1 is also disclosed.

Alfalfa hybrids having at least 75% hybridity

An alfalfa product, hybrids and non-hybrids, and a method for synthesizing an alfalfa product having increased uniformity for preselected traits having improved uniformity of one or more selected traits, including flowering dates, flower frequency, maturity rate, growth rate, fall dormancy and winterhardiness. The alfalfa product may also include improved predictability of these traits. A scheduled harvest system may be established using two or more varieties of the alfalfa product having different and predictable mean flowering dates. The scheduled harvest system may be designed to allow for harvesting of alfalfa varieties at maximum relative feeding value. The method may be used to synthesize an alfalfa product having one or more predetermined traits. The method selects germplasm, including a cytoplasmic male sterile line, a genetic male sterile line, a maintainer line, a restorer line and a line having normal cytoplasm, having agronomically desirable traits. Plants grown from the germplasm are classified and grouped for predetermined traits at different stages of testing and seed increase. The method selects genetically desirable plants having the predetermined traits for seed increase.
