Abstract
Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs), a distant wild relative of common wheat, possesses rich potentially valuable traits, such as disease resistance and more spikelets and kernels per spike, that could be useful for wheat genetic improvement. Development of wheat – P. huashanica translocation lines will facilitate its practical utilization in wheat breeding. In the present study, a wheat – P. huashanica small segmental translocation line, K-13-835-3, was isolated and characterized from the BC1F5 population of a cross between wheat – P. huashanica amphiploid PHW-SA and wheat cultivar CN16. Cytological studies showed that the mean chromosome configuration of K-13-835-3 at meiosis was 2n = 42 = 0.10 I + 19.43 II (ring) + 1.52 II (rod). GISH analyses indicated that chromosome composition of K-13-835-3 included 40 wheat chromosomes and a pair of wheat – P. huashanica translocation chromosomes. FISH results demonstrated that the small segment from an unidentified P. huashanica chromosome was translocated into wheat chromosome arm 5DS, proximal to the centromere region of 5DS. Compared with the cultivar wheat parent CN16, K-13-835-3 was highly resistant to stripe rust pathogens prevalent in China. Furthermore, spikelets and kernels per spike in K-13-835-3 were significantly higher than those of CN16 in two growing seasons. These results suggest that the desirable genes from P. huashanica were successfully transferred into CN16 background. This translocation line could be used as novel germplasm for high-yield and, eventually, resistant cultivar breeding.

Abstract
KEY MESSAGE YrSM139-1B maybe a new gene for effective resistance to stripe rust and useful flanking markers for marker-assisted selection were developed. ABSTRACT Stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important foliar disease of wheat. Two dominant stripe rust resistant genes YrSM139-1B and YrSM139-2D were pyramided in bread wheat cultivar Shaanmai 139; one from wild emmer and the other from Thinopyrum intermedium. Three near-isogenic F7:8 line pairs (contrasting RILs), N122-1013R/S, N122-185R/S, and N122-1812R/S, independently derived from different F2 plants and differing at the YrSM139-1B locus were generated from the cross Shaanmai 139 × Hu 901-19 through marker-assisted selection. A large F2:3 population from cross N122-1013R × N122-1013S tested for stripe rust response and subjected to analysis with markers in the 1BS10-0.5 bin region using SSR expressed sequence tags (EST) and site-specific sequence markers developed from the 90 K Illumina iSelect SNP array. Five EST-STS markers and four allele-specific PCR markers were mapped to the YrSM139-1B region. The 30.5 cM genetic map for YrSM139-1B consisted of nine markers, two of which were closer to YrSM139-1B than Xgwm273, which was used in producing the contrasting RIL pairs. Race response data and allelism tests showed that YrSM139-1B is different from Yr10, Yr15, and Yr24/26/CH42.

Abstract
Puccinia striiformis f. sp. tritici, the causal agent of wheat stripe rust, frequently produces new races overcoming resistance in wheat cultivars. A recently identified race, V26 with virulence to Yr26 and many other stripe rust resistance genes, has a high potential to cause epidemics in China. In this study, teliospores from a single-urediniospore isolate of V26 (Pinglan 17-7) produced on the wheat line 92R137 (Yr26) were used to produce a sexual population through selfing by infecting Berberis shensiana plants under controlled conditions. One hundred and eighteen progeny isolates and the parental isolate were phenotyped for virulence/avirulence on 24 Yr gene lines of wheat. These progeny isolates were all avirulent to Yr5, Yr8, Yr15, and YrTr1 and virulent to Yr1, Yr2, Yr7, Yr9, Yr10, Yr17, Yr24, Yr25, Yr26, YrA, YrExp2, and YrV23, indicating that the parental isolate is homozygous avirulent or homozygous virulent at these loci. The progeny population segregated for avirulence to Yr6, Yr43, and YrSP at one locus (3 avirulent:1 virulent ratio); for virulence to Yr27 and Yr28 at one locus (3 virulent:1 avirulent); and for Yr4, Yr32, and Yr44 at two loci (15 virulent:1 avirulent). Among the eight segregating avirulence/virulence loci, association was found between virulence to Yr4 and Yr32, as well as between virulence to Yr6 and Yr43 based on χ(2) tests. From 82 genotypically different progeny isolates, 24 pathotypes and 82 multilocus genotypes were identified. The results show that a highly diverse population can be produced from a single isolate by selfing on a barberry plant and sexually produced population can be used to genetically characterize virulence of the stripe rust pathogen.
