Temperate horticulture is a very important component of horticulture as it is only confined to the hilly regions of a country. For fruit crops, it represents a group, which is physiologically diverse from the sub-tropical and tropical fruit crops grown in other regions. For vegetables and floriculture it has immense potential for the keeping the nation well supplied with off-season and exotic vegetables and flowers all the year round. This book, being published to mark the centenary year of the Indian Agricultural Research Institute 1905 u 2005, strives to highlight the status of temperate horticulture in India. Articles on biotechnological and bioinformatics, genetic resources and manipulation, cropping patterns, drip irrigation, hill horticulture and economics of temperate horticulture contributed by scientists from IARI, Dr. YS Parmar University of Horticulture and Forestry, NBPGR, CIPHET, CPRI and various RRS’s of IARI , NBPGR and ICAR Research Complex for Eastern and NEH Regions. The book will prove as a complete handbook of temperate horticulture as it will not only serve as a reference material for research workers in horticulture, but will also play a vital role in combating problems and planning future strategies in the field of horticulture.
