The discovery of H. pylori has been associated with gastric problems and, in severe cases, gastric cancer. Across the world, millions of people are suffering from peptic ulcer, which may progress to gastric cancer. The pathogen is generally transmitted through contaminated food and water sources or from an infected person to others. The prevalence of H. pylori infections arises chiefly in developing countries, because many of these countries suffer extremely from a test and treatment approach.This...

These studies presence of sufficient exploitable genetic variability for various yield related traits among the rice genotypes. A good number of rice genotypes were screened and identified on the basis of various morphological, physiological and molecular studies, that would be used in the development of F1 hybrid seed. The genotypes CB-17, CB-32 and Basmati-198 were good general combiners for productive tillers per plant, primary branches per panicle and yield per plant, especially under water stress condition and also gave specific cross combinations for good yield and yield related traits....

Adoption of every new technology always involves advantages and risks; Bt cotton is new technology; which in developed countries is well known for many advantages like reduced application of pesticides, better insect pest control and higher lint yield but its success in developing countries still carries a question mark. Global adoption of Bt cotton has risen dramatically from 0.76 million hectares in its introductory period in 1996 to 7.85 million hectares in 2005. This book aims that adoption of Bt cotton may prove to be green revolution in enhancing the cotton yield. Although adoption of...
