Wheat is the most widely grown staple food crop in the world and accounts for dietary needs of more than 35% of the human population. Current status of transgenic wheat development is slow all over the world due to the lack of a suitable transformation system. In the present study, an efficient and reproducible Agrobacterium-mediated transformation system in bread wheat (Triticum aestivum L.) is established. The mature and immature embryos of six recently released high yielding spring bread whea...

Lack of uniformity of plant stand while conducting a field experiment can substantially contribute to errors in the prediction of association between plant phenotype and genotype. Among the several factors that can contribute to experimental errors, inconsistent seed depth and plant spacing often occur due to lack of precision when seeds are sown by hand or seed drills. Hence, we compare three planting methods, novel dibbling, seed drill, and hand sowing, to determine the most efficient method f...

Wheat is a major cereal crop and is grown in a wide range of agroecologies across the world. Abiotic stresses such as heat stress (HS), drought, waterlogging (WL), salinity, ultraviolet radiation B (UVR-B), ozone (O3), mineral deficiency (MD), and heavy metal toxicity (HMT) are the major constraints to wheat cultivation in its present form or in the future amplified version under changing global climate. These stresses alone or in combined form can pose a serious intimidation on the grain qualit...

Supraoptimal temperatures and unpredictable fluctuations in global climate adversely affect plant growth and development resulting in a severe threat to wheat production. Although all the growth stages of wheat are sensitive to supraoptimal temperatures, the reproductive phase is the most sensitive one as it affects both grain setting and grain filling (GF). High temperature can alter biochemical, physiological, and morpho-anatomical behavior in wheat, which in turn affects its growth and develo...

Terminal heat stress (THS) causes abrupt modulation in the expression of stress-related proteins in developing seeds. These differential expressions are thought to enhance thermotolerance. Hence, a field experiment was conducted with three spring wheat genotypes, Raj 4014 (heat sensitive), K 7903 (heat escaper) and WH 730 (heat tolerant), for the identification of THS-associated proteins. To expose the plants to different levels of temperatures at the time of grain filling, the crop was sown dur...

The canopy greenness, a visible indicator of crop nitrogen content, photosynthetic efficiency and overall crop health status is directly influenced by chlorophyll content. A lot of ambiguity exists over use of available chlorophyll meters and proper time of measurement during the day. In order to find differences between chlorophyll meters and the effect of diurnal variation of irradiance on chlorophyll measurements, three different chlorophyll meters (atLEAF+, Opti-sciences CCM200 and SPAD-Mino...
Fusarium head blight (FHB) or head scab is emerging as a destructive disease affecting the quantity and quality of wheat worldwide. Several Fusarium spe-cies have been associated with the disease but their composition varies among geographical regions and years. Climatic factors like temperature, pH and humidity influence the growth, survival and infestation of Fusarium species. In the present study, response of thirty six isolates of three Fusarium spp. viz F. graminearum, F. oxysporum and F. p...

Terminal heat stress has the potential negative impact on wheat production across the world, especially in South Asia. Under the threat of terminal heat stress, wheat genotypes with stay green trait would suffer from high temperature stress during their long grain filling duration (GFD). The genotypes with short GFD would be advantageous. To identify quantitative trait loci (QTL) for heat tolerance, a RIL population of K 7903 (heat tolerant) and RAJ 4014 (heat sensitive) wheat genotypes was inve...
