in wheat na+ exclusion and k+/na+ have shown to be associated with salinity tolerance, therefore in order to identify qtls with additive effect for na+ and k+ concentration traits in roots and shoots of wheat, 319  bread wheat recombinant inbred lines (ril f7), derived from a cross between roshan cultivar (salt tolerant) and falat cultivar (salt sensitive), along with their parents and 2 checks...

heat stress is a major environmental stress limiting wheat productivity in most cereal growing areas of the world. in order to map and characterize quantitative trait loci controlling heat tolerance, 144 recombinant inbred lines deriving from the cross of kauz and mtrwa116 were assessed in a greenhouse and growth chamber at 35°c. one hundred and sixty six ssr and 3 aflp markers were used to...

Fusarium head blight (FHB) remains a devastating disease in bread wheat (Triticum aestivum L.). Genetic resistance to FHB is complex; aside from active physiological resistance, plant developmental and morphological traits indirectly affect progression provide passive mechanism. Here, the relationship between Type II spike architecture was evaluated recombinant inbred line (RIL) population of f...

Abstract Spike fertility index (SF) is a trait easily measured at maturity and strongly associated with the number of grains per unit area. In order to identify genomic regions involved in SF control, biparental (Baguette 10 × Klein Chaja) population 80 recombinant inbred lines (RIL) was used. Seven field trails were conducted determine BLUP value RIL. RILs genotyped using commercial chip (Axio...

Dough rheological and starch pasting properties play an important role in determining processing quality in bread wheat (Triticum aestivum L.). In the present study, a recombinant inbred line (RIL) population derived from a Gaocheng 8901/Zhoumai 16 cross grown in three environments was used to identify quantitative trait loci (QTLs) for dough rheological and starch pasting properties evaluated ...

Leaf rust and powdery mildew are two important foliar diseases in wheat. A recombinant inbred line (RIL) population, obtained by crossing bread wheat cultivars (‘Victo’ ‘Spada’), was evaluated for resistance to the pathogens at seedling stage. Upon developing a genetic map of 8726 SNP loci, linkage analysis identified three Quantitative Trait Loci (QTLs), with ‘Victo’ contributing resistant all...

Stripe rust (yellow rust) caused by Puccinia striiformis f. sp. tritici, one of the most dangerous diseases wheat. Marker assisted selection methods make it possible to accelerate resistance gene donors improve breeding material through their introduction into hybridization programs. The goal this study was determine presence/absence yellow genes in wheat recombinant inbred lines Almaly/Avocet ...

Journal of Plant Registrations, Vol. 4, No. 2, May 2010 159 ‘USG 3209’/‘Jaypee’ (U/J) (Reg. No. MP-3, NSL 465777 MAP) is a soft red winter wheat (Triticum aestivum L.) recombinant inbred line (RIL) population developed by Virginia Polytechnic Institute and State University and submitted to the USDA–ARS National Small Grains Germplasm Research Facility in Aberdeen, ID, in 2008. This mapping popu...
