Zakia: A new Ug99-resistant variety for the heat stressed environments of Sudan

TextPublication details: 2013Description: p. 51Summary: Development of heat-tolerant high-yielding rust resistant common wheat varieties with good end-use quality under the heat stressed environments of Sudan is a daunting challenge. To determine the grain yield performance and stability of 21 new genotypes and three checks (Debeira, Bohaine and Nebta), field trials were conducted during the 2009-2011 cropping seasons at eight locations representing wheat growing areas in Sudan. AMMI (Additive Main Effect and Multiplicative Interaction) analysis showed that grain yield was significantly affected y genotypes, environments, and genotype × environment interaction. AMMI estimates across environments also showed that the grain yield of Zakia was 117, 102 and 96% of Debeira, Bohaine and Nebta, respectively. Zakia was identified as a leading genotype by GGE biplot analysis across a number of test environments. Zakia also had better end-use quality characteristics for HMW-GS composition, protein content, farinograph dough development time and dough stability time than the three checks. Screening with Pgt race Ug99 over four seasons in Kenya confirmed that the adult plant response of Zakia was R-MR. It also has APR to leaf rust and stripe rust. Based on these results, Zakia was officially released for commercial production in Sudan in 2013.

Abstract only
Development of heat-tolerant high-yielding rust resistant common wheat varieties with good end-use quality under the heat stressed environments of Sudan is a daunting challenge. To determine the grain yield performance and stability of 21 new genotypes and three checks (Debeira, Bohaine and Nebta), field trials were conducted during the 2009-2011 cropping seasons at eight locations representing wheat growing areas in Sudan. AMMI (Additive Main Effect and Multiplicative Interaction) analysis showed that grain yield was significantly affected y genotypes, environments, and genotype × environment interaction. AMMI estimates across environments also showed that the grain yield of Zakia was 117, 102 and 96% of Debeira, Bohaine and Nebta, respectively. Zakia was identified as a leading genotype by GGE biplot analysis across a number of test environments. Zakia also had better end-use quality characteristics for HMW-GS composition, protein content, farinograph dough development time and dough stability time than the three checks. Screening with Pgt race Ug99 over four seasons in Kenya confirmed that the adult plant response of Zakia was R-MR. It also has APR to leaf rust and stripe rust. Based on these results, Zakia was officially released for commercial production in Sudan in 2013.
