Genome Mapping and Molecular Breeding in Plants presents the current status of the elucidation and improvement of plant genomes of economic interest. The focus is on genetic and physical mapping, positioning, cloning, monitoring of desirable genes by molecular breeding and the most recent advances in genomics. The series comprises seven volumes: Cereals and Millets; Oilseeds; Pulses, Sugar and Tuber Crops; Fruits and Nuts; Vegetables; Technical Crops; and Forest Trees. Fruits and nuts form the largest group among crop plants. Several constraints such as long life cycle, heterozygosity and large plant size caused comparatively slow research progress in the past. The chapters on 20 fruit and nut crops authored by 56 renowned scientists from 12 countries include for the first time comprehensive reviews on mango, banana, olive, pineapple, pistachio, persimmon and papaya. Other crops covered are apple, grape, cherry, plum, peach, pear, apricot, strawberry, raspberry, blueberry, almond, citrus and avocado.
