Presented here are modern and classical aspects of cytogenetics as well as biotechnology in relation to improvement of the Festuca-Lolium group of grasses. Festuca and its close relative Lolium are very valuable genera of temperate agriculture. These fascinating genera contain some highly productive, nutritious, and well-adapted grasses widely used for agricultural and recreational purposes world wide. The book is organizedinto 15 chapters devoted to taxonomy and systematics; species evolution and divergence by increase in chromosome number as well as by change in DNA content; genetic control...

The esculent Lycopersicon esculentum, long thought to be poisonous, has become a major U. S. food crop and source of vitamins and minerals, thanks largely to genetic modification and new production technology Rick (1978) Tomato (Lycopersicon esculentum Mill. ) is one of the most important solana ceous vegetable crops grown worldwide under outdoor and indoor conditions. It has become an important commercial crop so far as the area, production, industrial values and its contribution to human nutrition is concerned. During the past few decades tremendous developments have contributed to the...

Because of the great variety of problems which this genus presents to biologists, Oenothera belongs to the best-known genera of plants not used economically. This book summarizes today's knowledge of Oenothera's genetics and related fields like caryology and cytogenetics. It is further of great value for all those whose research topics are based on genetics, such as developmental and evolutionary biology.

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...

In late 1971 we were involved in a study of the interaction of radiation with matter and were trying to use measurements of radiation fluorescence in biological molecules to indicate how radiation affected living cells. It soon became apparent that we were working in the dark; the doses we used to get a significant signal were too large to be of interest for radiation biology and although the DNA molecule appeared to be the most likely target molecule we did not know which sort of events and which sort oflesions were the most important. We decided to alter our approach to see if we could find...

" . . . . . . Nature has something more in view than that its own proper males should fecundate each blossom. " Andrew Knight Philosophical Transactions, 1799 Sterility implicating the male sex solely presents a paradoxical situation in which universality and uniqueness are harmoniously blended. It maintains a built-in outbreeding system but is not an isolating mechanism, as male steriles, the "self-emasculated" plants, outcross with their male fertile sibs normally. Both genes (nuclear and cytoplasmic) and environment, individually as well as conjointly, induce male sterility, the former...

A century of research on heterostylous plants has passed since the publication of Charles Darwin's book "The Different Forms of Flowers on Plants of the Same Species" in 1877 summarizing his extensive observations and experiments on these complex breeding systems involving genetic polymorphisms of floral sex organs. Since then heterostylous plants have provided a rich source of material for evolutionary biologists and today they represent one of the classic research paradigms for approaches to the study of evolution and adaptation. The present book is the first modern and comprehensive...

The present status of rapeseed-mustard crops as the third most important source of edible oils is attributable to the success of plant breeders and associate researchers in developing high yielding varieties with improved quality and resistance to biotic and abiotic stresses. However, the need to maximize the production gains and quality at lower economic costis greater than ever before. "Breeding Oilseed Brassicas" was thus conceived to review the past accomplishments in order to identify research gaps and suggest ways and means to meet the challenge of sustainable productivity upgradation....
