Description

FIELD OF INVENTION This invention is in the field of wheat (Triticum aestivum L.) breeding, specifically relating to a wheat variety designated 6PTTB30B. BACKGROUND OF INVENTION There are numerous steps involving significant intervention in the development of any novel, desirable plant germplasm. The goal is to combine in a single variety an improved combination of desirable traits from the parental germplasm. These traits may include, but are not limited to, higher seed yield, resistance to diseases and/or insects, tolerance to drought and/or heat, altered milling properties, abiotic stress tolerance, improvements in compositional traits, and better agronomic characteristics. Wheat is grown worldwide and is the most widely adapted cereal. There are five main wheat market classes. They include the four common wheat (Triticum aestivum L.) classes: hard red winter, hard red spring, soft red winter, and white (hard and soft). The fifth class is durum (Triticum turgidum L.). Common wheats are used in a variety of food products such as bread, cookies, cakes, crackers, and noodles. In general, the hard wheat classes are milled into flour used for breads and the soft wheat classes are milled into flour used for pastries and crackers. Wheat starch is also used in the paper industries, as laundry starches, and in other products. SUMMARY OF THE INVENTION Seeds of the wheat variety 6PTTB30B are provided. Also provided are plants produced by growing the seed of the wheat variety 6PTTB30B, as well as the derivatives of such plants. Further provided are plant parts, including cells, plant protoplasts, plant cells of a tissue culture from which wheat plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants, such as leaves, stems, roots, root tips, anthers, pistils, seed, grain, pericarp, embryo, pollen, ovules, cotyledon, hypocotyl, spike, floret, awn, lemma, shoot, tissue, petiole, cells, and meristematic cells, and the like. In a further aspect, a composition comprising a seed of wheat variety 6PTTB30B comprised in plant seed growth media is provided. The plant seed growth media can be, for example, a soil or synthetic cultivation medium. The growth medium may be comprised in a container or may, for example, be soil in a field. Plant seed growth media are well known to those of skill in the art and include, but are in no way limited to, soil or synthetic cultivation medium. Advantageously, plant seed growth media can provide adequate physical support for seeds and can retain moisture and/or nutritional components. Examples of characteristics for soils that may be desirable in certain embodiments can be found, for instance, in U.S. Pat. Nos. 3,932,166 and 4,707,176. Synthetic plant cultivation media include those known in the art and may, for example, comprise polymers or hydrogels. Examples of such compositions are described in U.S. Pat. No. 4,241,537. A tissue culture of regenerable cells of the wheat variety 6PTTB30B is provided, as well as plants and plant parts regenerated therefrom, wherein the regenerated wheat plant is capable of expressing all the physiological and morphological characteristics of a plant grown from the wheat seed designated 6PTTB30B. A wheat plant comprising a locus conversion or single locus conversion of the wheat variety 6PTTB30B, wherein the wheat plant is otherwise capable of expressing all the physiological and morphological, or phenotypic, characteristics of the wheat variety 6PTTB30B is provided. The locus conversion may comprise, for example, a transgenic gene which has been introduced by genetic transformation into the wheat variety 6PTTB30B or a progenitor thereof. The locus conversion may, for example, comprise a dominant or recessive allele or a genetic modification introduced by manipulation of the plant genome. The locus conversion may confer potentially any trait upon the converted plant, including, but not limited to, herbicide resistance, insect resistance, resistance to bacterial, fungal, or viral disease, male fertility or sterility, abiotic stress, altered phosphorus content, altered antioxidants, altered essential amino acids, and altered nutritional quality, such as altered starch, sugars, non-digestible carbohydrate, protein, oil or fatty acids. The altered trait can be compared to a wheat variety 6PTTB30B not comprising the locus conversion. Wheat plants are provided which comprise a transgene or genetic modification and which were produced by transforming or modifying the plant, plant part, seed or cell of wheat variety 6PTTB30B, or which had the transgene or the genetic modification introgressed through back-crossing. Methods for producing a wheat plant are provided in which plant breeding techniques are applied to a wheat plant grown from seed of wheat variety 6PTTB30B comprising a locus conversion, or to a plant grown from seed of a cross of such a wheat plant to a different wheat plant.
