Abstract

Breeding wheat for stem rust resistance caused by Puccinia graminis f.sp. tritici (Pgt) is a priority work worldwide including Ethiopia. Most of the major stem rust resistance genes deployed in commercial durum wheat cultivars and breeding lines succumb to emerging races in Ethiopia. In this study, 156 durum wheat accessions consisted of cultivars, landraces and advanced lines were exposed to the three e stem rust races (TTTTF, TTRTF, and JRCQC) at the seedling and adult plant growth stages. The seedling test was conducted in the greenhouse while the field tests in a single race nursery at Debre Zeit at Debre Zeit research center during 2019 and 2020 seasons. An augmented design with three replicated checks in every 20 entries was used in the field experiments while the seedling test was carried out based on the standard procedures. Of the 156 entries; only 22 (14%) and 25 (16%) exhibited resistance at seedling and adult plant growth stages. Of the tested CIMMYT advanced lines, 89% of the lines were susceptible to the race TTTTF, while 11% of the lines were resistant to this race at seedling stage. Of the total tested entries, 16 and 11% were resistant to all the three races at seedling and field condition, respectively. Six accessions exhibited overall resistance (at seedling and adult plant growth stages), while seven entries (two cultivars, two landraces, and three CIMMYT advanced lines) showed susceptible reaction (high infection types) at seedling stage and low severity (resistance) under field conditions to the three races; these accessions possibly have adult plant resistance to stem rust. Further pre-breeding (and genotyping) research is recommended to identify and characterize the stem rust resistance genes in those wheat germplasm associated to overall and adult plant resistance.

An augmented design with three replicated checks in every 20 entries was used in the field experiments while the seedling test was carried out based on the standard procedures. Of the 156 entries; only 22 (14%) and 25 (16%) exhibited resistance at seedling and adult plant growth stages. Of the tested CIMMYT advanced lines, 89% of the lines were susceptible to the race TTTTF, while 11% of the lines were resistant to this race at seedling stage. Of the total tested entries, 16 and 11% were resistant to all the three races at seedling and field condition, respectively. Six accessions exhibited overall resistance (at seedling and adult plant growth stages), while seven entries (two cultivars, two landraces, and three CIMMYT advanced lines) showed susceptible reaction (high infection types) at seedling stage and low severity (resistance) under field conditions to the three races; these accessions possibly have adult plant resistance to stem rust. Further pre-breeding (and genotyping) research is recommended to identify and characterize the stem rust resistance genes in those wheat germplasm associated to overall and adult plant resistance.
