A process is described for producing hybrid seed using male-sterile plants created by employing molecular techniques to manipulate antisense DNA and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing antisense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.

The present invention provides methods of marker assisted selection for high oleic/low linolenic traits in canola and in other oil seed crop species, as well as isolated nucleic acids for use as molecular markers in such methods. In particular, molecular markers and Brassica nucleic acid corresponding to fad2 and fad3 gene mutations are disclosed. The markers of the present invention are highly useful for the direct selection of desirable fad2 and fad3 alleles during marker-assisted trait introgression and breeding. In a one aspect of the embodiment, two single nucleotide polymorphism (SNP) markers are provided which correspond to the alleles. Thus, the present invention advantageously permits one of skill in the art to breed for the molecular markers described herein, or derivatives thereof, rather than breeding for a high oleic/low linolenic phenotype.

A computer-based system for characterizing in real time the nutritional components of one of more ingredients for a ruminant feed ration, including dry matter, NDF, NDFd, lignified NDF ratio, peNDF, percent starch, IVSD, and particle size for a forage material; and IVSD and particle size for a grain material. The system utilizes proprietary NIRS equations based upon prior samplings of a variety of crop species like dual-purpose corn silage, leafy corn silage, brown midrib (“BMR”) corn silage, grass (silage/dry), alfalfa (silage/dry), BMR forage sorghum, normal dent starch grain, floury endosperm starch grain, vitreous endosperm grain, and steam-flaked corn grain, and applies those equations to current samplings of a corresponding crop to predict in real time the characteristics of such forage or grain material. The real-time characterization system may also utilize the predicted data to calculate a “total ration fermentation index” value that takes into account the total NDFd and IVSD characteristics (including RAS and RBS) of the forage and starch ingredients to be used in a feed ration to ensure that the ration will not contribute too much or too little digestibility to the cow. A “flash fermentation index” identifies feed formulations, based upon the real-time characterizations of the ingredients, that are too “hot” to feed to the cows without incurring the risk of lost production and adverse health issues.
