the stady and analysis of rice agroclimatology in lenjan
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولIdentifying Novel Resistance Genes in Newly Introduced Blast Resistant Rice Germplasm
Blast, Magnaporthe oryzae B. Couch, and sheath blight, Rhizoctonia solani Kühn, are major fungal diseases of cultivated rice (Oryza sativa L.) in theUSA. Resistance toU.S.M. oryzae races was observed in 91 newly introduced rice accessions, suggesting these accessions are possible sources of novel blast resistance genes (Pi-genes) that could be incorporated into U.S. rice cultivars. The genes Pi...
متن کاملLarge scale germplasm screening for identification of novel rice blast resistance sources
Rice is a major cereal crop that contributes significantly to global food security. Biotic stresses, including the rice blast fungus, cause severe yield losses that significantly impair rice production worldwide. The rapid genetic evolution of the fungus often overcomes the resistance conferred by major genes after a few years of intensive agricultural use. Therefore, resistance breeding requir...
متن کاملDevelopment of Dominant Rice Blast Pi-ta Resistance Gene Markers
genotypes can be easily identified (Huang et al., 1997; Hittalmani et al., 2000). A PCR-based Pi-ta gene marker Incorporation of resistance genes into existing rice (Oryza sativa is useful in marker-assisted selection breeding since it L.) cultivars is a powerful strategy and is commonly applied in breeding rice resistance to blast disease [caused by Pyricularia grisea Sacc. is the part of resi...
متن کاملIntrogression of blast resistance genes into the elite rice variety MR263 through marker-assisted backcrossing.
BACKGROUND Blast caused by the fungus Magnaporthe oryzae is a significant disease threat to rice across the world and is especially prevalent in Malaysia. An elite, early-maturing, high-yielding Malaysian rice variety, MR263, is susceptible to blast and was used as the recurrent parent in this study. To improve MR263 disease resistance, the Pongsu Seribu 1 rice variety was used as donor of the ...
