The contributions of plant genetics to the production of higher yielding crops of superior quality are well documented. These successes have been realized through the application of plant breeding techniques to a diverse array of genetically controlled traits. Such highly effective breeding procedures will continue to be the primary method employed for the development of new crop cultivars; however, new techniques in cell and molecular biology will provide additional approaches for genetic modification. There has been considerable speculation recently concerning the potential impact of new...

Plant hormone research is the favorite topic of physiologists. Past three decades have witnessed that this subject has received much attention. The inquisitive nature of human mind has pumped much in literature on this subject and this volume is the product of such minds. In the following pages various hormonal-controlled physiological processes like, flowering, seed dormancy and germination, enzyme secretion, senes cence, ion transport, fruit ripening, root growth and development, thig momorphogenesis and tendril thigmonasty have been included. The volume also contains a review paper on...

Rhizobium species involved in root nodule formation on legume plants are one of the best known groups of micro- organisms. The Rhizobium legume symbiosis continues to be of strategic importance particularly in the context of food production. As the world population grows, it is also neces- sary to have new developments taking place in crop improve- ment. The development and application of new technologies in biological sciences over the past number of years have made the entire area of plant-microbial interaction an exciting and challenging research area to be involved in. In view of the...

'lbe rescue of immature embryos from wide crosses (Il) was one of the first applications of culture techniques in the cereals. Success with embryo culture has improved with increased knowledge of embryo development, differen tia tion pa ttems and nu tri tional and hormonal require men ts * lfowever, success in these procedures is still sporadic and often genotype or species specific. A review of embryo development is lacKing in recent literature on cereals. We shall first describe these processes, and follow this by a section on factors influencing embryo culture success. The rescue of...

Unlike the situation in the major cereals, the yields of Vicia faba have not been markedly increased during the last half century. There is no single cause for this but among those that have been important is the lack of cytogenetic understanding in relation to breeding performance. Since as a consequence, little genetic variation has been available to agronomists conclusions, probably unwarranted, have been drawn about the limited prospects for the faba bean. Against such a background it has been difficult to justify the investment of research resources in the crop. The central theme of this...

China was the first country to use cytoplasmic male sterility to develop hybrid rice for commercial use in 1973. In 1986 more than 8 million hectares of hybrid rice were planted in China, which is one fourth of the total rice area and produces one third of the total rice in the country. Hybrids usually out yield the leading commercial varieties by -20-30%, giving an average yield advantage of 1 to 1. 5 t/ha, because of their better morphological traits, higher physiological efficiency, better resistance to major diseases and insects, and wide adaptability to various agro-ecological stresses....

Adequate nitrogen fertilization is needed to obtain maximum crop yields. Without sufficient nitrogen available to the plant, other inputs are wasted. There are great differences between developed and develop ing areas of the world with regard to nitrogen-fertilizer production and application, resulting in serious food deficits in some of the most needy areas. Although nitrogen fertilizer is an inexpensive input in comparison to the resulting yield increases, chemical fertilizers must be purchased and do represent a direct cash outlay, sometimes the only cash require ment for the peasant...
