Abstract No. 139. Page 91 in: Program Book of the 89th Annual Meeting of the AACC. Interpretive Summary: Technical Abstract: In spite of a lengthy and costly process of 12-13 yr, wheat breeders must continue to develop and release new cultivars, as older cultivars tend to lose disease and pest resistance over 3-5 years. Three broad stages of breeding are the 1st stage (yr 1 & 2) of mating, the 2nd stage (yr 3 to 7) of inbreeding & selection, and the last stage (yr 8 to 12) of evaluation of breeding lines. Both genotype and wheat-growing environment (soil and climate) greatly influence the growth of plant, seed production, and the end-use quality. Breeding selects lines based on genotypic superiority of agronomical and end-use quality as well as the environmental stability on its growth and end-use quality. Additionally, wheat-exporting countries have to provide wheat with quality traits vital to the importing customers' own unique products. Active breeding programs of public and private sectors, or their corporative entities, share the common objectives: to improve agronomic, disease, and pest resistance so that wheat producers can enjoy high yield, wheat users (milling/baking industry) can have milling and end-use quality traits, while ensuring consumer satisfaction in the final products. Thus, 'breeding for quality, tailored for specific products' is the concerted efforts of all sectors, including cereal chemist/food technologists. The type of quality testing or definition of quality differs somewhat among different countries and it will be discussed in this presentation. |
