Genetic Improvement Of Rice For Salt Tolerance

This edited book is a compilation of tangible research findings and actual experiences on various salt tolerant rice breeding programmes, that have been successfully practiced and continuing to do so by research centres in South East Asia, with major emphasis in India, Bangladesh and Philippines. Rice being one of the most important staple crops of the world, its production and productivity have to be kept on increasing so as to feed the burgeoning population. This is a very challenging task in the midst of shrinking resource base and arable lands in the face of climate change. Salt stress is the second major abiotic stress, next only to drought, which greatly affects rice production. To overcome this problem, development of improved salt tolerant rice cultivars coupled with appropriate package of practices, an ecologically sound and socially acceptable strategy should be developed which is well within the reach of marginal farmers. With rapid advances in molecular biology, mechanisms underlying the complexity of the trait are better understood now than before. Selection of appropriate parents, desired mapping populations, precise phenotyping are the key components to underpin the mapping and utilization of reliable QTLs. Understanding genetics of salt tolerance, identifying the robust molecular markers and targeted utilization of available molecular markers form the sound basis to develop the commercial products with more precision and speed. This book covers entire range of topics: starting from biophysical characterization of salt stressed areas in different rice ecologies, conventional and molecular breeding approaches for mapping salt tolerance and subsequent development of improved rice varieties for commercial cultivation and their societal impacts. This book is of interest to scientists, faculty, policy makers and administrators. It also serves as a resource guide to graduate students of agriculture particularly plant breeding, plant physiology, molecular biology and soil science.

This book provides a fresh, updated perspective of the current status and perspectives in genetic improvement of a diverse array of tropical crops. The first part covers aspects which are relevant across crops, namely how to maximize the use of genetic information through modern bioinformatic approaches and how to use statistics as a tool to sustain increased genetic gains and breeding efficiency. The second part of the book provides an updated view of some seed-propagated crops, such as rice, maize and oil palm, as well as crops propagated through vegetative means such as sweet potato, cassava, banana and sugarcane. Each chapter addresses the main breeding objectives, markets served, current breeding approaches, biotechnology, genetic progress observed, and in addition a glimpse into the future for each of these selected and important tropical crops.

Wild Germplasm for Genetic Improvement in Crop Plants addresses the need for an integrated reference on a wide variety of crop plants, facilitating comparison and contrast, as well as providing relevant relationships for future research and development. The book presents the genetic and natural history value of wild relatives, covers what wild relatives exist, explores the existing knowledge regarding specific relatives and the research surrounding them and identifies knowledge gaps. As understanding the role of crop wild relatives in plant breeding expands the genetic pool for abiotic and biotic stress resistance, this is an ideal reference on this important topic. Provides a single-volume resource to important crops for accessible comparison and research Explores both conventional and molecular approaches to breeding for targeted traits and allows for expanded genetic variability Guides the development of hybrids for germplasm with increased tolerance to biotic and abiotic stresses

A comprehensive and groundbreaking collection of ideas for plant improvement Most of the world’s supply of legumes is cultivated under adverse conditions that make this commercially important crop susceptible to the vagaries of nature and damaging stresses. Genetic manipulation has become a proven way for cultivators to battle these problems; but there has been a lack of reliable information on the practical aspects of this promising method. Handbook of New Technologies for Genetic Improvement of Legumes fills this void by providing a vast array of groundbreaking essays from some of the discipline’s most renowned experts. This unique collection is your single source for not only the most up-to-date accounts of genetic manipulation employed today, but also ideas for realistic and practical uses. Comprehensive in its approach, Handbook of New Technologies for Genetic Improvement of Legumes presents the latest research on all aspects of genetically modified legume production.
