Cash Crops

Cash crops are grown and sold for monetary gain and not necessarily for sustenance. They include coffee, tea, coconut, cotton, jute, groundnut, castor, linseed, cocoa, rubber, cassava, soybean, sweet potato, potato, wheat, corn and teff. While some of these crops have been improved for realizing yield potential, breeding of many of them is still in infancy. Crops that underwent rigorous breeding have eventually lost much of the diversity due to extensive cultivation with a few improved varieties and the diversity in less bred species is to be conserved. Over the past years, scholars and policy makers have become increasingly aware of the short and long-run impact of climatic factors on economic, food security, social and political outcomes . Genetic diversity, natural and induced, is much needed for the future generations to sustain food production with more climate resilient crops. In contrast, crop uniformity produced across the farm fields in the form ofimproved varieties is genetically vulnerable to biotic and abiotic stresses. Thus, it is essential and challenging to address the issue of compromising between maximizing crop yield under a given set of conditions and minimizing the risk of crop failure when conditions change. Cash crops are grown in an array of climatic conditions. Many of the world's poor still live in rural areas. Many are subsistence farmers, operating very small farms using very little agricultural inputs for achieving marketable outputs. Conserving the diversity of these crops and addressing all issues of crop culture through modern tools of biotechnology and genomics is a real challenge. We believe the focus of this book is to fill an unmet need of this and other grower communities by providing the necessary knowledge, albeit indirectly via the academics, to manage the risks of cash crops breeding through managing genetic diversity.

Covers the genetic diversity and genetic diversity conservation of cash crops Provides assessment of genetic diversity in relation to climate change Addresses the molecular diversity of cash crops

He is a prominent Hevea *rubber breeder. He began his research career by breeding triticale and wheat while doing M.Phil and PhD degrees at the Chaudhary Charan Singh University, Meerut under the guidance of Prof. P.K. Gupta.. During the 1980s he focused on the *in vitro culture of spices. He joined the Rubber Research Institute of India (Rubber Board, Ministry of Commerce, Govt. of India) as a Plant Breeder in 1990 and specialized in breeding Hevea rubber for sub-optimal environments. He was a visiting scientist at the Hardwood Tree Improvement and Regeneration Centre, Purdue University, U.S.A. In 2009, he became the Institute's Deputy Director, and managed its Central Experiment Station until 2016. He has been involved in breeding cereals, spices and Hevea rubber for 32 years. He is a reviewer of several international journals like Industrial Crops & Products, Tree Genetics and Genomes etc. He has published several research papers and chapters in journals and books of international repute like Advances in Agronomy, Advances in Genetics, and Plant Breeding Reviews. He has edited books on Breeding Plantation Tree Crops (Springer), Breeding Major Food Staples (Blackwell-Wiley), and the Genomics of Tree Crops (Springer). He also authored books on the Biology of Hevea Rubber (Springer) and on Plant Breeding: Classical to Modern (Springer).
