Molecular Characterization of Slow Leaf-Rusting Resistance in Wheat
been widely used to characterize foliar disease resistance (Jeger and Viljanen-Rollinson, 2001) because it Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gainreflects both severity and rate of disease development ing acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously (Wilcoxson et al., 1975). IR and I...

15 صفحه اولEvaluation of Advance Wheat Lines for Slow Yellow Rusting (Puccinia striiformis f. sp. Tritici)
Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici is one of the most damaging diseases of wheat in Pakistan. Lack of durable resistance in local wheat varieties is the main reason for stripe rust epidemic which could limit yields. The use of genetically resistant wheat varieties is the most economic way of controlling the disease. Evaluation of 135 advance wheat lines for...
متن کاملDetermination of Rate of Degradation of Iron Plates Due To Rust Using Image Processing -A Review
most of industries and bridges around us make use of iron for manufacturing their products. On the other hand corrosion is a natural process that deteriorates the integrity of iron surface. Therefore, rusting of iron takes place. To avoid unwanted accidents in industries and bridges, it is necessary to detect rusting in earlier stage, so that it can be prevented. Digital image processing for th...
