Breeding Plantation Tree Crops: Tropical SpeciesShri Mohan Jain, P.M. Priyadarshan Tree species are indispensable to support human life. Due to their long life cycle and environmental sensitivity, breeding trees to suit day-to-day human needs is a formidable challenge. Whether they are edible or industrial crops, improving yield under optimal, sub-optimal and marginal areas calls for uni?ed efforts from the s- entistsaroundtheworld. Whiletheuniquenessofcoconutaskalpavriksha(Sanskr- meaning tree-of-life) marks its presence in every continent from Far East to South America, tree crops like cocoa, oil palm, rubber, apple, peach, grapes and walnut prove their environmental sensitivity towards tropical, sub-tropical and temperate climates. Desert climate is quintessential for date palm. Thus, from soft drinks to breweries to beverages to oil to tyres, the value addition offers a spectrum of pr- ucts to human kind, enriched with nutritional, environmental, ?nancial, social and trade related attributes. Taxonomically, tree crops do not con?ne to a few families, but spread across a section of genera, an attribute so unique that contributes immensely to genetic biodiversity even while cultivated at the commercial scale. Many of these species in?uence other ?ora to nurture in their vicinity, thus ensuring their integrity in p- serving the genetic biodiversity.

Tree crops face an array of agronomic and horticultural problems in propagation, yield, appearance, quality, diseases and pest control, abiotic stresses and poor shelf-life. |
