This book shows the importance of rice for human consumption. It focuses on the rice panicle, its morphology and characteristics. High genetic diversity of rice has been economically profitable for mankind; the crop provides food calories to half of the human race on earth and because of its adaptability to diversified and unstable ecological conditions, the plant has an asynchronous flowering system in the panicle. The International Rice Research Institute has a collection of panicles with numerous branching phenotypes and lengths varying from 10 to 43 cm. Due to the heterogeneous architecture, grain filling depends on the position of the spikelet within a panicle. Spikelets on apical branches fertilize early and fill faster compared to their basal counterparts and therefore, individual grain weights of panicle vary widely. The discrepancy in grain filling between spikelets changes with panicle architecture but the relationship of variation in individual grain weight with panicle architecture has not been studied. Spikelet number has increased highly in the newly developed rice cultivars, but it has no benefit accrued on grain filling and yield. This book is recommended for students, researchers and teachers working in this field of expertise.

The innovative theme of the International Treatise Series on “Advances in Plant Physiology”, Volume 12 “Physiological and Molecular Interventions for Crop Improvement under Changing Environments” has been especially edited for rational use by planners, scientists, investigators, academicians and postgraduate students. This book is an exceptional assimilation of timely, vital and inclusive twelve worthy reviews of varied significance, especially in view of the changing macro- and micro-climate influencing physiology of plants at all levels, contributed by true commitment of experienced, laudable and well-known scientists/ stalwarts all over the world. This is also strongly realized that there is with time more a need of united effort for the holistic development in the agricultural sciences, which absolutely depends on environmental situations. The threat of changing climate has imposed challenge to world scientists and their efforts in understanding reasons of yield reductions at physiological and molecular levels have been intensified. The consistent outcome are imparted with genetic engineers who have to now under the present circumstances exclusively identify, isolate and purify specific genes from DNA sequences befitting for development of tolerance mechanism in crop plants under changes of different degrees of intensity in environment. That is naturally the step wise long process having several pros and cons to arrive at any conclusion. Hence, the treatise series is the need of the hour and excellent source to disseminate meaningful distilled thoughts emerging out of extensive research which has due relevance for planning consequential basic strategic research besides direct help to the mankind. The intricacies of abiotic and biotic stresses on growth and development of plants have been understood in the last few decades. This book too is an endeavour to make aware the young workers to gain information on researches of basic and applied significance for extending consequential research of physiological and molecular approaches for crop improvement under changing environment. The manifold ideas on basic problems of the present and the future as well as resolutions, in part, have been consolidated which will be accomplished in subsequent volumes.

Rice is a staple food for half of the worlds population mostly in Asia. Productivity of rice has largely been improved since the Green Revolution in 1960s. Further improvement of rice yield is necessary to keep pace with population growth, which is a challenging task for breeders. This book, Rice - Germplasm, Genetics and Improvement, as its name implies, comprehensively reviews current knowledge in germplasm exploration, genetic basis of complex traits, and molecular breeding strategies in rice. In the germplasm part, we highlight the application of wild rice in rice breeding. In the genetics part, most of the complex traits related with yield, disease, quality have been covered. In the improvement part, Chinese experiences in hybrid rice breeding have been summarized together with many molecular breeding practices scattering in different chapters.

Outlining successful breeding techniques to augment the yields of the world's major crops, this reference analyzes the physiological and genetic basis for past and potential future increases in crop yields.;Covering crops with wide differences in morphology, photosynthetic rates, and nitrogen metabolisms, Genetic Improvement of Field Crops: investigates the changes produced by breeders in the physiological attributes affecting wheat grain yield and nitrogen content during the last century; discusses those crop characteristics of oats that have already been altered or might be manipulated through breeding to further increase yield potential; describes several genetic factors responsible for both yield potential and stress resistance in barley; offers insights into the relationship between increases in the yield potential and stress tolerance of corn; examines the evolution of sunflower crop yields and yield stability and estimates the contribution of improved cultivars; evaluates the effects of breeding on tuber characteristics related to the crop growth and yield of the potato; elucidates the possibilities for simultaneous improvement of yield and fiber strength in cotton; and identifies the features to be considered in the development of high yielding varieties of rice for different agricultural systems.;Providing nearly 1600 key literature citations allowing further in-depth study of particular topics, Genetic Improvement of Field Crops is for plant physiologists and breeders, crop and agricultural scientists, agronomists, biochemists, geneticists, biotechnologists, microbiologists, and upper-level undergraduate and graduate students in these disciplines.
