The application of unmanned aerial vehicle (UAV) remote sensing technology for high-throughput acquisition phenotypic values field plant height is great significance in monitoring wheat varieties (lines). Based on the UAV, mounted with high-resolution digital cameras, a low-altitude platform was built to obtain images Berkut/Worrakatta recombinant inbred lines (RIL) population (297 lines). opti...

The bread-making quality of wheat is strongly influenced by multiple low molecular weight glutenin subunit (LMW-GS) proteins expressed in the seeds. However, the organization, recombination and expression of LMW-GS genes and their functional mechanism in bread-making are not well understood. Here we report a systematic molecular analysis of LMW-GS genes located at the orthologous Glu-3 loci (Gl...

Recombinant inbred lines (RIL) derived from multiple inbred strains can serve as a powerful resource for the genetic dissection of complex traits. The use of such multiple-strain RIL requires a detailed knowledge of the haplotype structure in such lines. Broman (2005) derived the two- and three-point haplotype probabilities for 2(n)-way RIL; the former required hefty computation to infer the sy...

Calreticulin (CRT), an endoplasmic reticulum (ER)-localized Ca2+-binding/buffering protein, is highly conserved and extensively expressed in animal and plant cells. To understand the function of CRTs in wheat (Triticum aestivum L.), particularly their roles in stress tolerance, we cloned the full-length genomic sequence of the TaCRT-D isoform from D genome of common hexaploid wheat, and charact...

Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces w...

Gray leaf spot (GLS) caused by Cercospora zeae-maydis or zeina is one of the devastating maize foliar diseases worldwide. Identification GLS-resistant quantitative trait loci (QTL)/genes plays an urgent role in improving GLS resistance breeding practice. Two groups recombinant inbred line (RIL) populations derived from CML373 × Ye107 and Chang7-2 were generated subjected to genotyping-by-sequen...

Recombinant inbred lines (RIL) population (F7) of two A-genome progenitors i.e. T. monococcum and T. boeoticum were evaluated for various yield affecting parameters. For all the traits under study enlisting components of variance, genetic advance and heritability were observed to be showing highly significant differences (P ≤ 0.01). Trend of high phenotypic coefficients of variation (PCV) estim...

We consider fixed recombinant inbred lines (RILs) derived either by selfing or by full-sib mating; when applicable, we also consider intermated recombinant inbreds (IRIs). First, we show that the usual estimate of recombination fraction based on RIL data is biased, and we provide an estimate where the major part of that bias is removed. Second, we derive simple formulas to compute the frequenci...

Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
