“…It is located on chromosome 1A and distributed in many wheat cultivars. Gene Lr10 is not widely effective on its own but may play a positive role in gene combinations (McIntosh et al 1995). In addition to the above listed cultivars possessing Lr10 in combination with Lr37 (Bakfis, Barryton, Biscay, Caphorn Mulan and Rapsodia) or Lr26 (Clarus, Etela and Rapsodia) gene Lr10 was determined by the molecular marker in cvs.…”

Twenty-seven winter wheat cultivars registered in the Czech Republic were tested by molecular markers for the presence of Lr26 and Lr37, and twenty-eight cultivars for the presence of Lr10. Gene Lr37 was determined in eleven cultivars, gene Lr10 in ten cultivars and gene Lr26 in four cultivars. Eight cultivars had combinations of two Lr genes, one cultivar possessed all the three Lr genes. The results of marker analyses were compared with multipathotype analysis which confirmed the presence of Lr26 but did not enable the verification of the presence of Lr10 and Lr37. Seedling resistance was compared with resistance of the studied cultivars in the field.

“…Studies at Sydney University found that VPM1 harbours three rust resistance genes: the leaf rust resistance gene Lr37, stem rust resistance gene Sr38 and yellow rust resistance gene Yr17. These three genes are closely linked to the wheat chromosome 2AS (Bariana & McIntosh 1993) and have been used all over the world (McIntosh et al 1995). Helguera et al (2003), using RFLP marker cmwg682, positioned Lr37-Yr17-Sr38 linkage group at 10 cM of chromosome 2AS from the telomere or centromere 2AS.…”

Wang J., Li Z., Shi L., Zhu L., Ren Z., Li X., Liu D., Shah S.J.A. (2015): QTL mapping for adult-plant leaf rust resistance genes in Chinese wheat cultivar Weimai 8. Czech J. Genet. Plant Breed., 51: 79-85.The wheat cultivar Weimai 8 is a good source of adult-plant resistance to leaf rust in China. In order to understand the genetic background of the resistance genes, 179 F 2:3 families derived from the cross Weimai 8 and Zhengzhou 5389 (susceptible to leaf rust) were used to construct a linkage map. Results showed that there was a major QTL on chromosome 2AS, temporarily named QLr.hbau-2AS, responsible for the resistance. QLr.hbau-2AS from the resistant parent Weimai 8 was between the SSR markers Xcfd36 and Xbarc1138, with an interval length of 2.58 cM. In the 2010-2011, 2011-2012 and 2012-2013 crop seasons, it explained 25.79, 71.55 and 60.72% of the phenotypic variation, respectively. The location of QLr.hbau-2AS was close to the leaf rust resistance gene Lr37. However, they may not be the same since QLr.hbau-2AS has a different virulence test response from Lr37. This study identified two closely linked flanking molecular markers QLr.hbau-2AS and these molecular markers will help marker-assisted selection in breeding resistant cultivars in the future.

Timopheevii wheats are discussed as donors for improving the disease resistance of common wheat. Attention is paid to the comparison of the morphological and chromosomal characteristics of Triticum timopheevii and T. militinae, their crossability with T. aestivum and their response to fungal diseases. The possible origin of T. militinae from an introgressive hybridization between T. timopheevii and an unknown species is discussed. Major genes for resistance to various fungal diseases, transferred to common wheat from T. timopheevii, are listed.
