Plant breeders take this further by cross-pollinating plants (manually placing pollen from one plant on the stigma of another) that have desirable characteristics, harvesting the resulting seed, and selecting new individuals that have combined desirable traits from both parents. Acclimatization 3. World's largest germplasm collection of coconut (comprising 401accessions 269 indigenous and 132 exotic) is being maintained in the Institute.
