Comparisons are carried out among genotypes for particular regions. For example, for two farming
regions location 3 in France and location 16 in Greece, the total irrigation demand and harvest of 20
genotypes is shown in Fig.6. For location 3, the genotype “Melody” has a distinctly higher harvest and a
slight higher irrigation demand than the others. Therefore it is recommended for this region. For location
16, the biggest harvest genotype is still “Melody”, but it requires substantial irrigation. Searching for a
genotype that has smaller irrigation demand will result in a reduced harvest. The genotype “Heliasol” has
the second largest harvest with a clear decrease of irrigation. This genotype is preferred considering the
drought condition in this area. Comparisons are also made among regions for particular genotypes. For
example, Fig.7 illustrates the irrigation demand and harvest for genotype “Remil” and ‘Melody” in 25
farming region. Irrigation amounts vary widely among regions, whilst harvest levels are sorted in little
various levels. The best farming region for “Melody” is location 19 in Portugal, because it has a low
irrigation demand and a comparably good harvest. Compared with location 16 in Greece, its irrigation
amount is 10 times smaller, and its harvest is bigger. Compared with location 1 in France, its harvest is a
slightly smaller, but its irrigation demand costs 10 times less. Selections require a compromise between
irrigation and harvest, and depend on the project objectives and actual situation, such as the irrigation
capacity.
