“…In soybean, pyramiding of Rpp2, Rpp4, and Rpp5 in a single genotype was shown to provide higher resistance to ASR . Higher resistance of this pyramided line to Brazilian ASR isolates was also confirmed in subsequent experiments (Yamanaka et al 2013b). Maphosa et al (2012) reported a low level of ASR severity and sporulation through Rpp2, Rpp3 and Rpp4 pairwise gene pyramiding.…”

Since Asian soybean rust (ASR) isolates in South America are highly virulent, diverse, and distantly related to Japanese ones, limited numbers of resistance resources are available in soybean breeding in that region. Pyramiding of available ASR resistance genes (Rpp) in a single soybean genotype may provide wider spectrum and higher level of ASR resistance to soybean. However, the desired combinations of genes conferring adequate resistance to highly virulent or distantly related ASR isolates have not yet been studied. In this study, seven pyramided lines carrying multiple Rpp genes have been developed and evaluated for their resistance against one ASR isolate from Japan and two from Brazil. Significantly higher resistance was observed in the pyramided lines, No6-12-B (Rpp4 + Rpp5), Oy49-4 (Rpp2 + Rpp3 + Rpp4), and No6-12-1 (Rpp2+Rpp4+Rpp5) compared to the original resistance sources, PI 230970 (Rpp2), Hyuuga (Rpp3), PI 459025 (Rpp4), and Kinoshita (Rpp5) carrying single Rpp genes. Although infection of the resistance sources with the highly virulent Brazilian ASR isolates resulted in susceptible phenotypes with moderate to abundant sporulation, highly resistant phenotypes with almost no sporulation were observed in the three Rpp-pyramided lines. Therefore, pyramided lines carrying these Rpp gene combinations are useful in soybean breeding for conferring broad spectrum, high resistance to ASR isolates that are virulent to the varieties carrying single resistance genes.

“…Although constraints have limited the use of MAS in plant breeding programs in Brazil (Sakiyama et al 2014), use of molecular markers is effective for some traits, mainly in transfer of major genes (Santana et al 2014, Yamanaka et al 2013, Dimitrijević et al 2017. The use of backcrossing may be the best approach to transfer low linolenic acid and high oleic acid contents to elite cultivars.…”

“…This reaction will inhibit the fungus development. Lesion color is known to be controlled by resistance genes of Rpp2 and Rpp4, thus it should be considered when selecting resistant genotypes (Yamanaka et al 2010;2013). On susceptible lines, lesion was clearer (Tan) and some were mixture between RB and Tan, even though most of the lesion type in this study was RB.…”

Abstract. Inayati A, Yusnawan E. 2016. Characterization of soybean genotypes for Asian soybean rust reaction under screen house condition. . Asian soybean rust (ASR) caused by Phakopsora pachyrhizi is one of the major diseases limiting soybean yield. This disease has widely spread on soybean crops in Indonesia. The use of resistant cultivars is one of the economical approaches to control ASR. The objectives of this study were to assess the resistance of soybean lines derived from crossing two largeseeded cultivars (Baluran and Grobogan) with a broad adaptive cultivar (Kaba) and to identify resistant genotype characteristics under screen house conditions. All genotypes were artificially inoculated with P. pachyrhizi uredospores. Number of pustules per leaf, the development of ASR, and yield components including number of intact pods per plant, number of empty pods, and weight of pods per plant were observed. Thirteen lines of Baluran pedigrees had higher resistant response to ASR compared to Grobogan pedigrees. Fewer numbers of pustules (8 pustules cm -2 ), lower value of area under the disease progress curve (AUDPC), and redish brown (RB) lesion type were observed in resistant lines. In contrast, susceptible lines had more pustules (> 21 pustules cm -2 ), higher AUDPC value, and had mixed lesion type (RB and Tan). ASR reduced seed size and yield. The average weight of 100 seeds of resistant lines was 10.2 g while on susceptible lines, the 100-seed weight ranged from 8.7 to 12.6 g. The average yield per plant varied from 2.7 to 6.1 g. Baluran/Grobogan pedigrees were more susceptible to ASR than Baluran/Kaba pedigrees, however, those pedigrees showed better yield per plant and were supposedly more tolerant to ASR.
