Lodging affects grain quality and yield in wheat (Triticum aestivum L.) is difficult to breed for because its sporadic incidence laborious protocols measure lodging traits. Thus, developing molecular markers these traits can increase selection efficiency breeding programs. The aim of this article identify quantitative trait loci (QTL) associated with stem/anchorage strength leverage (lodging tr...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...

ABSTRACT- Bromus danthoniae Trin. is an annual grass species which grows mainly on dry grassy rocky mountain slopes and grassy steppe, and is grazed by many herbivores and recognized as a useful pasture plant. The chromosome number, morphological and anatomical traits of 82 genotypes of B. danthoniae belonging to three sub-taxa were investigated. Twenty-seven quantitative and 20 qualitative mor...

African rice gall midge (AfRGM) is one of the most destructive pests of irrigated and lowland African ecologies. This study aimed to identify the quantitative trait loci (QTL) associated with AfRGM pest incidence and resistance in three independent bi-parental rice populations (ITA306xBW348-1, ITA306xTOG7106 and ITA306xTOS14519), and to conduct meta QTL (mQTL) analysis to explore whether any ge...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...

QTL underlying related traits at the late developmental stage under two different nitrogen levels were investigated in rice using a population of chromosome segment substitution lines (CSSL) derived from a cross between Teqing and Lemont. A total of 31 QTLs referring 5 traits, that is, plant height (PH), panicle number per plant (PN), chlorophyll content (CC), shoot dry weight (SDW) and grain y...

drought stress is one of the important problems in arid and semi_arid regions. drought stress take place in plants when available water is lesser than evapotranspiration. in order to evaluate the effect of drought stress on morphological traits and yield of three medicinal plants an experiment was carried out during the 2010 year in research greenhouse of faculity of agriculture, ferdowsi unive...

Type III effectors play a vital role in the establishment of symbiosis. In this study, positive and negative effects NopT on nodulation were detected 30 soybean germplasms. The quantitative trait loci (QTL) related to nodule number identified their responses recombinant inbred lines chromosome segment substitution evaluated. Ten QTL chromosomes 02, 05, 06, 10, 13. One overlapping region 02 was ...
