“…Many wheat-alien chromosomal translocation lines carrying desirable genes have been reported in recent years [8,54,55], but some have not been fully utilized in wheat breeding due to the incomplete compensation for the replaced wheat chromosomal segments. Only wellcompensating translocations were beneficial in wheat improvement.…”

Agropyron cristatum (L.) Gaertn. (2n = 28, PPPP), a wild relative of common wheat, possesses many potentially valuable traits that can be transferred to common wheat through breeding programs. The wheat-A. cristatum disomic addition and translocation lines can be used as bridge materials to introduce alien chromosomal segments to wheat. Wheat-A. cristatum 2P disomic addition line II-9-3 was highly resistant to powdery mildew and leaf rust, which was reported in our previous study. However, some translocation lines induced from II-9-3 have not been reported. In this study, some translocation lines were induced from II-9-3 by 60 Co-γ irradiation and gametocidal chromosome 2C and then identified by cytological methods. Forty-nine wheat-A. cristatum translocation lines were obtained and various translcoation types were identified by GISH (genomic in situ hybridization), such as whole-arm, segmental and intercalary translocations. Dual-color FISH (fluorescent in situ hybridization) was applied to identify the wheat chromosomes involved in the translocations, and the results showed that A. cristatum 2P chromosome segments were translocated to the different wheat chromosomes, including 1A, 2A, 3A, 4A, 5A, 6A, 7A, 3B, 5B, 7B, 1D, 4D and 6D. Many different types of wheat-A. cristatum alien translocation lines would be valuable for not only identifying and cloning A. cristatum 2P-related genes and understanding the genetics and breeding effects of the translocation between A. cristatum chromosome 2P and wheat chromosomes, but also providing new germplasm resources for the wheat genetic improvement.

“…Dasypyrum villosum (syn. Haynaldia villosum) is an allogamous annual diploid grass that has been found to carry many important agronomic traits, especially those for high resistance to wheat diseases, such as rust (Hyde, 1953;Chen et al, 2002), powdery mildew (Qi et al, 1993;Chen et al, 1995;Li et al, 2005), spindle streak mosaic viruses (Zhang et al, 2005), wheat curl mite Li et al, 2002), and eyespot. Genes for high salt and drought tolerance (Qualset et al, 1981;Blanco et al, 1983;Zhong and Dvorak, 1995), high efficiency of zinc use (Schlegel et al, 1998), and increased grain protein content have also been identified.…”

“…However, these genes have not yet been fine mapped. In order to be able to exploit the genetic resources of D. villosum, many chromosome addition lines, sub-stitution lines and translocation lines have been constructed for use in the transfer of beneficial genes into cultivated wheat (Chen et al, 1995Zhang et al, 2005;Gradzielewska, 2006). Zhao et al (2010) developed two new compensating Robertsonian translocation lines, T1DL•1V#3S and T1DS•1V#3L.…”

ABSTRACT. The transfer of agronomically useful genes from wild wheat species into cultivated wheat is one of the most effective approaches to improvement of wheat varieties. To evaluate the transfer of genes from Dasypyrum villosum into Triticum aestivum, wheat quality and disease resistance was evaluated in two new translocation lines, T1DL•1V#3S and T1DS•1V#3L. We examined the levels of stripe rust resistance and dough quality in the two lines, and identified and located the stripe rust resistant genes and high molecular weight glutenin subunit (HMW-GS) genes Glu-V1 of D. villosum. Compared to the Chinese Spring (CS) variety, T1DL•1V#3S plants showed moderate resistance to moderate susceptibility to the stripe rust races CYR33 and Su11-4. However, T1DS•1V#3L plants showed high resistance or 8077-8083 (2015) immunity to these stripe rusts. The genes for resistance to stripe rust were located on 1VL of D. villosum. In comparison to CS, the dough from T1DS•1V#3L had a significantly shorter developing time (1.45 min) and stable time (1.0 min), a higher weakness in gluten strength (208.5 FU), and a lower farinograph quality index (18). T1DL•1V#3S had a significantly longer developing time (4.2 min) and stable time (5.25 min), a lower weakness in gluten strength (53 FU) and a higher farinograph quality index (78.5). We also found that T1DS•1V#3L had reduced gluten strength and dough quality compared to CS, but T1DL•1V#3S had increased gluten strength and dough quality. The results of SDS-PAGE analysis indicated that Glu-V1 of D. villosum was located on short arm 1VS and long arm 1VL. These results prove that the new translocation lines, T1DS•1V#3L and T1DS•1V#3L, have valuable stripe rust resistance and dough quality traits that will be important for improving wheat quality and resistance in future wheat breeding programs.

“…The species D. villosum has been extensively hybridized with wheat for at least 6 decades. Several disease resistance genes have been successfully transferred to wheat including those effective against powdery mildew ( Pm21 [Chen et al, 1995]; Pm55 ), wheat spindle streak mosaic virus ( Wss1 [Zhang et al, 2005]), and stem rust ( Sr52 ). Cytological and molecular evidence suggested the occurrence of significant genomic diversification between the 2 Dasypyrum species [De Pace et al, 2011;Baum et al, 2014;Li et al, 2016], and research has been conducted with the aim to transfer useful genes from D. breviaristatum into wheat.…”

Dasypyrum breviaristatum (genome V^bV^b) contains potentially important traits for commercial wheat production. Chromosome 2V^b of D. breviaristatum carries several desirable agronomic characters, including long spike length as well as enhanced resistance to stripe rust, which are expressed in a common wheat background. In this study, wheat-D. breviaristatum 2V^b deletion lines were produced and identified by fluorescence in situ hybridization (FISH), and 74 molecular markers specific to D. breviaristatum chromosome 2V^b were physically localized in 4 distinct chromosomal regions. New wheat-D. breviaristatum 2V^b translocation lines were also characterized by FISH. The breakpoint of the translocation T3AS.3AL-2V^bS was determined by physically mapped molecular markers. Field evaluation revealed that genes affecting plant height and spike length are located on fraction length (FL) 0.65-1.00 of 2V^bS, while the stripe rust resistance gene(s) are located on FL 0.40-1.00 of D. breviaristatum chromosome 2V^bL. The newly characterized wheat-Dasypyrum chromosomal introgressions are of potential value for the improvement of the yield and disease resistance of wheat.
