Book Description
A stagnation of wheat yield was reported in France and other countries worldwide since the 1990's, which incriminated mainly drought and heat stress. Improving the European wheat tolerance to them is of first importance. This study aimed to investigate the genetic determinism of the tolerance to such stresses. Three CIMMYT bread wheat populations combining complementary heat and drought adaptive habits were grown in Northern Mexico under irrigated, drought and heat-irrigated treatments from 2011 to 2013. The trial network comprised 15 trials and both physiological and agronomic traits were scored. First, an environmental characterization methodology was developed and resulted in the identification of six main environmental scenarios in the network. A representative environmental covariate was extracted from each of them. Then, a factorial regression model leaded to the dissection of the genotype-by-environment interaction and highlighted differential stress sensitivity of the germplasm. Finally, a multi-environmental QTL detection resulted in the discovery of genomic regions involved in the control of both physiological and agronomic traits and the study of their sensitivity to the environment. From the environmental characterization to the QTL detection, this study resulted in the development of a tool for breeders which may enable the evaluation of the potential of any genotypes in front of a range of environment, but also the identification of genomic regions involved in the control of the tolerance to drought and heat stress in bread wheat. This may help in improving the tolerance of the European bread wheat germplasm to drought and heat stress.

Book Description
The present investigation was carried out with an aim to studying some physio-morphological characters of wheat associated with yield under different soil moisture stress. The soil moisture stress as a whole reduced the yield and yield contributing characters of wheat. Correlation analysis of grain yield with yield attributing characters indicated a high positive correlation coefficient with total dry matter, crop growth rate, leaf number/plant, harvest index, spikelet number/spike and 1000 kernel weight. Growth analysis showed that both crown root initiation and heading stages were the critical and care is needed at these stages for better crop yield. However, heading stage was more critical. Stress study clearly showed that the varieties differed from one another in their tolerance to stress and among the varieties studied, Gaurab was comparatively least susceptible one while Aghrani was the highest highest susceptible. Phenotypic regression analysis also showed that Gaurab had unit regression slope with low stability value for grain yield/plant, fertile tiller number and 1000 kernel weight indicating its stability to varying soil moisture treatments.

Book Description
Wheat Blast provides systematic and practical information on wheat blast pathology, summarises research progress and discusses future perspectives based on current understanding of the existing issues. The book explores advance technologies that may help in deciding the path for future research and development for better strategies and techniques to manage the wheat blast disease. It equips readers with basic and applied understanding on the identification of disease, its distribution and chances of further spread in new areas, its potential to cause yield losses to wheat, the conditions that favour disease development, disease prediction modelling, resistance breeding methods and management strategies against wheat blast. Features: Provides comprehensive information on wheat blast pathogen and its management under a single umbrella Covers disease identification and diagnostics which will be helpful to check introduction in new areas Discusses methods and protocol to study the different aspects of the disease such as diagnostics, variability, resistance screening, epiphytotic creation etc. Gives deep insight on the past, present and future outlook of wheat blast research progress This book’s chapters are contributed by experts and pioneers in their respective fields and it provides comprehensive insight with updated findings on wheat blast research. It serves as a valuable reference for researchers, policy makers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat.
