In bread wheat, QTL interval mapping was conducted for nine important drought responsive agronomic traits. For this purpose, a doubled haploid (DH) mapping population derived from Kukri/Excalibur was grown over three years at four separate locations in India, both under irrigated and rain-fed environments. Single locus analysis using composite interval mapping (CIM) allowed detection of 98 QTL,...
A major objective of quantitative trait loci (QTL) studies is to find genes/markers that can be used in breeding programs via marker assisted selection (MAS). From an extensive review, we surveyed the distribution of QTL for yield and yield-related traits on wheat genome. In order to identify the important regions involving in these traits, QTL meta-analysis was performed. As a result, 55 MQTL ...
Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...
In order to study inheritance of traits (Height, Peduncle length, Extrusion peduncle length, Diameter first internode, Diameter secondary internode, Diameter third internode length of secondary internode, length of third internode) associated with height in bread wheat, seven cultivars of bread wheat with their F1 progenies produced through a half diallel mating design were planted in a randomi...

This paper investigates a simplified polarimetric decomposition for soil moisture retrieval over agricultural fields. In order to overcome the coherent superposition of the backscattering contributions from vegetation and underlying soils, a simplification of an existing polarimetric decomposition is proposed in this study. It aims to retrieve the soil moisture by using only the surface scatter...
Digital repeat photography is becoming widely used for near-surface remote sensing of vegetation. Canopy greenness, which has been used extensively for phenological applications, can be readily quantified from camera images. Important questions remain, however, as to whether the observed changes in canopy greenness are directly related to changes in leaf-level traits, changes in canopy structur...
breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...
A factorial experiment with forty one triticale genotypes and two wheat cultivars (‘Kavir’ bread wheat cultivar and ‘Dipper-6’ durum wheat cultivar as salt-tolerant genotypes) as the first factor and six salinity levels of 0, 0.5, 1, 1.5, 2 and 2.5 percent (0, 85, 170, 255, 340 and 425 mM) of NaCl as the second factor was conducted. Results indicated that the increase of salinity level has lead...
In this study, a regional winter wheat yield prediction method was developed by integration of time series of Moderate-Resolution Imaging Spectroradiometer MODIS LAI products (MOD15A2) with WOrld FOod STudies (WOFOST) model through Ensemble Kalman Filter (EnKF) algorithm at the regional scale in the Hengshui District, Hebei province in China. WOFOST model was selected as the crop growth dynamic...
