• No. of explorations in Africa and South America
• Carried out with the cooperation of host countries
• Collected materials shared equally
• Cost borne by MPOB; partly IBPGR

SAMPLINGSAMPLING
• Sampling method devised using rainfall,
soil, density of palm groves;
• 5-10 palms per site (population) sampled;
• Number of sites visited in a country
depends on density of palm groves;
• A bunch harvested from each sampled
palm;
• Seedlings derived from a bunch are
considered as an ‘open-pollinated’ family.
