Improving wheat stripe rust resistance in Central Asia and the Caucasus

Reduction of Winter Wheat Yield Losses Caused by Stripe Rust through Fungicide Management

“…The study was conducted in Fergana in 2010 using a stripe rust susceptible, widely grown winter wheat variety 'Kroshka' (Ziyaev et al 2011). The experimental design was similar to that explained above for Tajikistan.…”

“…This study was conducted in Karshi and Surkhandarya, Uzbekistan, in 2009-2010(2010) and 2010-2011(2011 scores were recorded in the control plots between growth stages Z69 and Z79. At maturity, plots were individually harvested, threshed and grain yield recorded.…”

Sources and Donors for Soft Wheat Selection by Resistance to Yellow Rust

“…In 2013, the yellow rust affected the most susceptible species in some areas of Afghanistan, Azerbaijan, India, Iran, Iraq, Morocco, Pakistan, Turkey and Uzbekistan [6][7][8] . In recent years, phytosanitary situation is deteriorated in Central and Eastern Asia and North Africa, as well in Kazakhstan, in connection with the spread of yellow rust of wheat 9,10 . Five epiphytoties outbreaks of yellow rust took place in the region over the past 15 years (in 1998, 2000, 2005, 2009 and 2010.).…”

“…Five epiphytoties outbreaks of yellow rust took place in the region over the past 15 years (in 1998, 2000, 2005, 2009 and 2010.). That led to significant losses of wheat crop 10 . The pathogen is found in the territory of Kazakhstan almost every year, except for extremely dry years 11 .…”

Identification of Wheat Stripe Rust Resistance Genes in Iranian Wheat Cultivars Using Molecular Markers

“…This gene is known to show high levels of resistance to stripe rust in China [47,49] and Turkey [50]. Also, in surveys of resistance genes in the Caucasian region and middle Asia [51] and Pakistan [11], Yr5 and Yr15 were identified to be effective against all Pst races. The fact that Yr5 is effective in Iran and its surrounding countries makes it a good candidate for wheat breeding programs.…”
