This open access book presents simple, robust pre-field screening protocols that allow plant breeders to screen for enhanced tolerance to heat stress in rice. Two critical heat-sensitive stages in the lifecycle of the rice crop are targeted – the seedling and flowering stages – with screening based on simple phenotypic responses. The protocols are based on the use of a hydroponics system and/or pot experiments in a glasshouse in combination with a controlled growth chamber where the heat stress treatment is applied. The protocols are designed to be effective, simple, reproducible and user-friendly. The protocols will enable plant breeders to effectively reduce the number of plants from a few thousands to less than 100 candidate individual mutants or lines in a greenhouse/growth chamber, which can then be used for further testing and validation in the field conditions. The methods can also be used to classify rice genotypes according to their heat tolerance characteristics. Thus, different types of heat stress tolerance mechanisms can be identified, presenting opportunities for pyramiding different (mutant) sources of heat stress tolerance.

Information available for other cereals and the limited or circumstantial evidence available for rice indicate that we can now breed varieties that have improved yield under drought and produce high yields in the good seasons. This manual aims to help plant breeders develop such varieties.

In this manual, we provide detailed protocols for screening rice under the major stresses affecting both rainfed and irrigated rice: submergence, salinity, drought, and the soil problems – excess iron and aluminum. We also include protocols for a new area of abiotic stress research since it is increasingly occurring in farmers’ field due to climate change: combined stresses. Results from these protocols on combined drought + salinity and submergence + salinity indicate that the effects on the rice plant are sometimes different than under individual stresses. The protocols in this manual have been developed and optimized over decades at IRRI. Numerous scientists, technical staff and students have been involved in the development and use of these protocols, and it is often their experiences that have led to improvements, all of which are highly acknowledged. Our objective with this compilation is to provide a resource for researchers around the globe who aim to improve the abiotic stress tolerance of rice as part of the effort to benefit rice farmers in both rainfed and irrigated areas affected by abiotic stresses

This book provides a comprehensive overview of the multiple strategies that plants have developed to cope with drought, one of the most severe environmental stresses. Experts in the field present 17 chapters, each of which focuses on a basic concept as well as the latest findings. The following major aspects are covered in the book: · Morphological and anatomical adaptations · Physiological responses · Biochemical and molecular responses · Ecophysiological responses · Responses to drought under field conditions The contributions will serve as an invaluable source of information for researchers and advanced students in the fields of plant sciences, agriculture, ecophysiology, biochemistry and molecular biology.
