“…Wheat cereal introduction 2401 (CI2401) from Tajikistan was resistant to the original biotype (RWA1) (Porter et al 1993(Porter et al , 2005. After the appearance of RWA2, Collins et al (2005a) screened 761 germplasm accessions previously determined to be resistant to RWA) and showed that CI2401 also has resistance to RWA2.…”

“…This result reflects the Mediterranean and/or Asian regions as the probable source of RWA resistance in U.S. germplasm. Porter et al (1993) reported that of 12,000 cultivars and introductions screened for RWA response, all the resistant lines identified came from these regions. Sub-cluster Ia consisted of 21 RWA accessions predominantly resistant to both biotypes, and 20 of them came from Iran.…”

“…Most originate in eastern Mediterranean and Asian regions where RWA is endemic, including Turkey, Syria, Iran, Afghanistan, and southern regions of the former Soviet Union (Porter et al 1993;Collins et al 2005). Porter et al (1993) reported that of 12,000 wheat cultivars and plant introductions (PI) screened for RWA, only 29 had moderate to high levels of resistance and all are from Mediterranean and Asian regions. This observation indicates low genetic diversity for wheat breeding for resistance to RWA.…”

“…Since then, it has caused severe economic damage, and losses were estimated to be $1 billion from cumulative yield reductions and insecticide application costs 10 years later (Morrison and Peairs 1998). Improving host-plant resistance is considered the most cost-effective and environmentally safe approach for controlling RWA (Porter et al 1993;Souza 1998;Smith et al 1999;Webster and Kenkel 1999;Collins et al 2005).…”

AFLP genetic diversity analysis in Russian wheat aphid resistant wheat accessions

et al. 2012

View full text Add to dashboard Cite

Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is an important insect pest which causes severe economic losses in wheat (Triticum spp.). Among the various U.S. RWA biotypes, biotype 1 (RWA1) and biotype 2 (RWA2) are the most prevalent and most virulent on cultivated genotypes. Although many sources of resistance to these biotypes are available among landraces, their relatedness should be characterized to permit their more efficient use in breeding programs. In this study, 38 hexaploid accessions resistant to biotype 1 and/or biotype 2 were evaluated for genetic diversity based on amplified fragment length polymorphisms (AFLP). Fifteen AFLP selective primer combinations were used to genotype these accessions, resulting in 893 amplicons. Of these, 274 (30.6%) informative polymorphic bands were used for genetic diversity analysis. Genetic similarity coefficients ranged from 0.47 to 0.87 among the resistant accessions, indicating high genetic diversity among them. Cluster analysis grouped the 38 accessions into two major clusters, I and II, including resistant lines for RWA1 and RWA2. The study indicated that accessions in the National Small Grains Collection conferring RWA1 or RWA2 resistance comprise a diversified population which should support introgression efforts and provide genetic diversity for future breeding for RWA resistance.

“…Therefore, primary screening is necessary to classify the varieties resistant to the aphids through artificial infection of plantlets by aphids in the greenhouse (Porter et al 1993;Tolamy et al 1999). In this study, at the two-to three-leaf stage of development, plants were transported to a growth chamber at a temperature of 20 ± 1°C, 60 ± 5% RH and 14:10 (L:D) h to perform the experiment.…”

Resistance and susceptibility of various wheat varieties to Sitobion avenae (Hemiptera: Aphididae) in Iran

The English grain aphid, Sitobion avenae (Fabricius), is a severe pest of wheat plants in temperate countries. Therefore, we carried out primary screening to assess the resistance or susceptibility of 23 commonly grown wheat varieties to this aphid at greenhouse and laboratory conditions in Iran. Also, population attributes of this aphid were evaluated on six wheat varieties, namely Saysonz, Arta, Moghan3, Zagros, Sardari and Shirodi. The aphids were colonized on the Hirmand wheat variety in a growth chamber at 20 ± 1°C, 60 ± 5% R.H. and a photoperiod of 14:10 (L:D). The tested varieties were grouped into three major classes including A (e.g., Shirodi, Falat and Moghan2), B (e.g., Sardari, Zagros and Tagan) and C (e.g., Arta, Saysonz, Moghan3 and Pishtaz). Also, the results of the life history traits showed that the developmental time of nymphal stage ranged from 7.5 days on Zagros to 10.8 days on Saysonz. The intrinsic rate of increase (r m ) of S. avenae varied from 0.133 (day -1 ) on Saysonz to 0.210 (day -1 ) on Shirodi. Jackknife estimates of other population parameters on these varieties were evaluated. As a result, our findings showed that the varieties Saysonz, Arta and Moghan3 were partially resistant against S. avenae, whereas Shirodi, Zagros and Sardari were relatively susceptible.
