Book Description
Racism in America has been the subject of serious scholarship for decades. At Harvard University Press, we’ve had the honor of publishing some of the most influential books on the subject. The excerpts in this volume—culled from works of history, law, sociology, medicine, economics, critical theory, philosophy, art, and literature—are an invitation to understand anti-Black racism through the eyes of our most incisive commentators. Readers will find such classic selections as Toni Morrison’s description of the Africanist presence in the White American literary imagination, Walter Johnson’s depiction of the nation’s largest slave market, and Stuart Hall’s theorization of the relationship between race and nationhood. More recent voices include Khalil Gibran Muhammad on the pernicious myth of Black criminality, Elizabeth Hinton on the link between mass incarceration and 1960s social welfare programs, Anthony Abraham Jack on how elite institutions continue to fail first-generation college students, Mehrsa Baradaran on the racial wealth gap, Nicole Fleetwood on carceral art, and Joshua Bennett on the anti-Black bias implicit in how we talk about animals and the environment. Because the experiences of non-White people are integral to the history of racism and often bound up in the story of Black Americans, we have included writers who focus on the struggles of Native Americans, Latinos, and Asians as well. Racism in America is for all curious readers, teachers, and students who wish to discover for themselves the complex and rewarding intellectual work that has sustained our national conversation on race and will continue to guide us in future years.

Book Description
Experiments which in previous years were made with ornamental plants have already afforded evidence that the hybrids, as a rule, are not exactly intermediate between the parental species. With some of the more striking characters, those, for instance, which relate to the form and size of the leaves, the pubescence of the several parts, etc., the intermediate, indeed, is nearly always to be seen; in other cases, however, one of the two parental characters is so preponderant that it is difficult, or quite impossible, to detect the other in the hybrid. from 4. The Forms of the Hybrid One of the most influential and important scientific works ever written, the 1865 paper Experiments in Plant Hybridisation was all but ignored in its day, and its author, Austrian priest and scientist GREGOR JOHANN MENDEL (18221884), died before seeing the dramatic long-term impact of his work, which was rediscovered at the turn of the 20th century and is now considered foundational to modern genetics. A simple, eloquent description of his 18561863 study of the inheritance of traits in pea plantsMendel analyzed 29,000 of themthis is essential reading for biology students and readers of science history. Cosimo presents this compact edition from the 1909 translation by British geneticist WILLIAM BATESON (18611926).

Book Description
Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species. Utilization of wild relatives of a crop depends largely upon its crossability relations with cultivated varieties. Sev eral wild species are not crossable with the commercial cultivars due to various isolation barriers. Furthermore, in a few cases, hybridiza tion is possible only in one direction and reciprocal crosses are not successful, thus depriving the utilization of desired cytoplasm of many species. However, techniques have been developed to over come many barriers and hybrid plants are produced. New crop species have been developed by overcoming the F 1 sterility and producing amphidiploids and such crops are commercially being grown in the field. The segregation pattern ofF 1 hybrids produced by distant hybridization in segregating generations are different from the intervarietal hybrids. In former cases, generally, unidirectional segregation takes place in early generations and accordingly, selec tion procedures are adopted. In most of the cases, backcross or modified backcross methods have been followed to utilize wild species, and thus numerous types of resistance and other economical attributes have been transferred in the recurrent parents. Protoplast fusion has been amply demonstrated in a number of cases where sexual hybridization was not possible and, as a result, hybrids have been produced.

Book Description
This book offers a detailed overview of both conventional and modern approaches to plant breeding. In 25 chapters, it explores various aspects of conventional and modern means of plant breeding, including: history, objective, activities, centres of origin, plant introduction, reproduction, incompatibility, sterility, biometrics, selection, hybridization, methods of breeding both self- and cross- pollinated crops, heterosis, synthetic varieties, induced mutations and polyploidy, distant hybridization, quality breeding, ideotype breeding, resistance breeding, breeding for stress resistance, G x E interactions, tissue culture, genetic engineering, molecular breeding, genomics, gene action and varietal release. The book’s content addresses the needs of students worldwide. Modern methods like molecular breeding and genomics are dealt with extensively so as to provide a firm foundation and equip readers to read further advanced books. Each chapter discusses the respective subject as comprehensively as possible, and includes a section on further reading at the end. Info-boxes highlight the latest advances, and care has been taken to include nearly all topics required under the curricula of MS programs. As such, the book provides a much-needed reference guide for MS students around the globe.
