CD 154: strong gluten wheat with high yield potential

Abstract

 Wheat breeding programs focus on potential grain yield, industrial quality, low plant height, and disease resistance. Cultivar CD 154 was a result of the search for cultivars with high yield potential and industrial wheat quality. This cultivar was derived from a cross between CD 104 and CDI 200104, by COODETEC, in 1999. Cultivar CD 154 was included in preliminary grain yield trials in 2005 and 2006, and was then tested to determine the Value of Cultivation and Use (VCU) from 2007 to 2012, with the acronym CD 0705. All trials were arranged in an experimental design of randomized blocks with three replications. The yield of cultivar CD 154 was 16 %, 10 % and 4 % higher than the mean yield of the two best controls, respectively, in the wheat-growing regions VCU 2, 3 and 4. The analysis of industrial quality, resulted in a mean gluten strength of 364 and mean stability of 17.1 min, which allows the inclusion cultivar CD 154 in the cultivar group of strong gluten wheat. The cultivar is classified as strong gluten wheat, has a high yield potential and good lodging resistance, and is therefore another promising alternative for wheat farmers of the hottest regions of Brazil.
